Ten Reasons to use EPI Air in your Barn

If you are a swine or poultry producer who wants to improve your production rates, it is time to learn about Electrostatic Particle Ionization (EPI) by Baumgartner Environics. EPI is a patented air-cleaning system, specially designed for reducing dust particles from agricultural settings and other confined spaces. Read more about how it works here.

Why use EPI to Improve your In-Barn Air Quality?

  1. Proven Dust Removal – USDA Studies and other test data show that EPI Air can help remove 50-80% of dust particles and aerosols from the air.
  2. Improve Animal Production – EPI Air has been shown to dramatically improve animal production and livability (See Murphy-Brown’s production gains).
  3. Employee Work Environment & Morale – Cleaner air makes it easier for employees to breathe inside the animal production area, creating a better work environment.
  4. Quick Return on Investment – Murphy-Brown calculated less than 34 weeks to get a ROI based on their own 99.9% statistically significant tests.
  5. Reduce Odors for Neighbors– EPI Air catches dust particles inside the barn, so gases and pathogens can’t “hitch a ride” on dust particles being emitted outside. Visitors and neighbors will appreciate reduced barn odors.
  6. Encourage Growth – Cleaner air can also relieve stress on animals, creating an environment that improves the rate of swine and poultry growth.
  7. Reduce Mortalities – EPI Air has been shown to reduce mortality rates (Mortalities reduced by 26.1% for Murphy-Brown).
  8. Innovative Combinations – EPI Air can be combined with other clean-air methods such as filtration for promising results.
  9. Fight PRRS – EPI Air may help PRRS infected pigs to fight secondary complications. 
  10. Worldwide Recognition– EPI Air is installed in barns across the globe. In fact, EPI complies with European standards for dust reduction with Certification in the Netherlands, and also has been invested in by the Canadian government in support of the Manitoba Pork Council.

Swine Quarantine Combines EPI Air and Filtration

A recent Quarantine Project in Canada is studying new ways that a bio-containment system could be adapted for a swine barn. The preliminary results of the study were presented by Francis Pouliot, Eng M.B.A of the CDPQ,  at the Annual Canadian Swine Health Forum. The objective of the project was to quarantine infected gilts and prevent the spread of viruses into the atmosphere. In addition to making sure the viruses stay inside the quarantine room, they also studied how a new ventilation system could reduce the rate of clogging and maintenance of the filters, cutting cost to an affordable rate. Clogging and maintenance of the filters is the main problem with the concept of installing filtration equipment over the exhaust fan of a swine quarantine building. This innovative quarantine project used a combination of EPI Air® and filtration to achieve promising results (Read the project summary here).

One of the key challenges of this quarantine system is reducing the clogging rate of the filters at the exhaust fans, in an affordable, maintenance-reducing way. This is where the EPI (Electrostatic Particulate Ionization) Air System is used.

The Ionization System:

  • The EPI Air System is used inside the building to reduce the concentration of dust in the ambient air.
  • EPI Air’s effect significantly reduced the clogging rate and maintenance needs of filters.

The Filtration System:

  • Cyclonic pre-filters and antimicrobial filters are installed in front of exhaust fans to prevent viruses from escaping quarantine. Additional filters are installed over air inlets to prevent PRRS virus or other airborne diseases from entering the quarantine room.
  • The efficiency of the cyclonic pre-filters and the antimicrobial filters at blocking dust and microbial load are measured with and without using EPI Air.

The preliminary results of the quarantine project are very promising. Take a look at the charts below from Francis Pouliot’s CDPQ Presentation, to  to see how EPI Air made a significant difference reducing the overall dust concentration in the room and how EPI Air extended the useful life of the filter box. We look forward to seeing the final results of this study.

A portion of this project funding was provided by the sector councils of Quebec, Ontario, Manitoba, and Saskatchewan who administer the Canadian Agricultural Adaption Program (CAAP) for Agriculture and Agri-Food Canada.

Reducing Secondary Complications in PRRS Infected Pigs

There is no doubt that the PRRS virus is a vital health concern for swine producers. PRRS (porcine reproductive and respiratory syndrome) is a highly infectious and deadly virus. It is reported that PRRS is the most economically significant disease to affect US swine production since the eradication of classical swine fever (CSF). But EPI Air may help.

EPI Air may help PRRS infected pigs fight secondary infections. USDA-ARS tests have shown ionization to reduce pathogens in the air. Also, cleaner air leads to fewer challenges of the pigs’ respiratory systems. These two factors may help PRRS-infected pigs avoid secondary complications.

Dr. Gary Bradley, Research Center Coordinator at Murphy-Brown LLC directed trials of the EPI Technology in their nursery facilities. At a recent Pork Expo, he was asked if EPI technology could possibly reduce the movement of the PRRS Virus, Bradley only ventured, “That might be a possibility. I don’t think the negative ions could eliminate the virus from the barn. However, combined with the overhead positioning of EPI units perhaps a portable unit used at floor level could be ‘zapping’ viruses after the wash down.” He speculates there likely will be additional technology that branches off from the current EPI system. As a research scientist he’s more than willing and ready to further explore new ideas. “Preliminary results were phenomenal in our nursery units so we’re totally open to stretching our minds about a further spin off of EPI technology.”

The Canadian government also sees potential with the EPI Air and improving the productivity of hog herds while boosting the bottom line for those in the hog industry. The government of Canada, in support of the Manitoba Pork Council, is investing over $150,000 to help improve the air quality in swine barns with the EPI Air System. PRRS is reported to cost the Canadian industry an estimated $130 million per year; so using the EPI Air system to reduce and prevent the airborne transmission of PRRS is a sound investment.

EPI Air has been proven to increase average daily gain, increase average weights, and decrease mortalities. Knowing that the EPI Air makes such a significant impact on overall swine performance provides a positive outlook towards the possibilities that EPI Air also holds for PRRS.

National Environmental Winner is Minnesota pork producer

By Dick Hagen, Hagen and Associates

Being honored as a National Environmental Winner in pork production is indeed a big deal. Only four such honorees nationwide each year. And in the 18 years since the program was initiated by the National Pork Producers Council, Minnesota has claimed 12 winners.

But winning awards is the least concern of Wayne and Laura Dahl, LacQuiParle County, MN pork producers and 2012 honorees in this illustrious event. More important, much more important is presenting their 240-acre farm, hog production facilities, and neatly landscaped and artistically decorated farmstead as an entity of rural pride.

“Stewardship is a commitment that comes along with farming,” commented Wayne adding, “The public holds us accountable to be good stewards, especially in this day and age of anti-livestock activists, hidden cameras, etc. We don’t want to be just another name on that abstract. For us it is a blessing and privilege to have a farm like this. We want to leave a legacy.”

The background of Wayne and Laura dates back to 1976 when Wayne bought the farm. “I fell in love with this farm the minute I drove up the driveway 36 years ago when we were married,” says Laura referring to the country charm of the old farmstead nestled amongst a shelterbelt of aged cottonwoods and other assorted trees.

Wayne raised hogs in his Dad’s older hog sheds initially but 1979 marked the building of their first farrowing/nursery facility and a finishing setup. “I helped my Dad with his hog operation which at that time was on dirt. Even my first farrowing of our own sow herd was at my Dad’s place but now everything is produced on slats. And it has been a major transformation,” he reflected.

“You may think that pigs on dirt have all that freedom and life is good. But the actuality is that it’s much harder to control flies, rodents, mud and just the weather in general. So as we could afford it we gradually moved more of our total hog operation inside on slats. We started on partial slats in our 1979 finishing house and could see immediate benefits.

“When 2003 rolled along and we got into our major expansion, we decided to go all slats. We’ve been pleased with the comfort of the pigs, the cleanliness of the pigs, the ability to take care of individual pigs as needed and of course the much greater efficiency and ease of our daily chores also,” said Wayne.

Their expanded operation now includes a 4,400-head nursery and four 1,100-head finishing barns. Pigs are grown on contract for Mill Farm, a 5,000-sow operation owned by Greg and Paul Boerboom, Marshall, MN. The Dahls receive six groups (about 4,400 pigs per group) of 21-day-old ‘freshly weaned’ nursery pigs a year from Mill Farm. Care taker of the nursery pigs is very much the responsibility of Laura. She is well qualified.

She has a medical lab technician and also worked as a hospital physical therapy aide so getting these ‘baby’ pigs off to a good start is her special challenge. “I love it,” she said. “These little rascals are always fun to watch. I carefully note their weights. Every batch has a few tail-enders so I sort them into their own pen and even provide a special mat, about 4’ x 6’, that I place over the slats close by their tube feeders. Three times a day I put some of the same starter ration on this mat so if they’re not yet ready to nibble at the tube feeders they can feed off this mat.”

She sorts and groups by size and makes certain they find the nipple waterers. Pigs in that ‘hospital pen’ get even closer attention. “I look at every pig, from snout to tail, every day. Treat your pigs well and they treat us well,” noted Laura. At 40 to 60 lbs, pigs move to finishing barns. Marketing is at about 280 lbs.

Technology gets noted

Anez Consulting Inc., Willmar, MN assists with nutrient management, crop scouting and the implementation of conservation practices on the farm. Manure from the 8’ deep pits is tested with application rates calibrated to meet the fertilizer needs for the next year’s crop. A 10,000-gal. tanker equipped with a flow meter applies the manure with GPS precision in soybean stubble.

The Dahls use a manure additive to help stabilize the nitrogen in the fall-applied manure. Also the feed additive, phytase, is used to reduce the amount of phosphorous in the manure. This enables them to boost manure application rates by up to 20% without building phosphorous in the soil.

Nothing gets ignored in a modern swine operation. Pig comfort is first and foremost in their operation. And that includes the adaption of a few ‘technological wrinkles’ still unfolding in much of the swine industry. But Wayne doesn’t mind being at the front end of new technologies. “He’s a technology nerd,” chuckled Laura. Wayne agreed, “Yes, we’ve come a long way in pork production and we’re always looking for new ideas that might help us to do a better job.”

Indeed. Like he was one of the first in the nation to install EPI technology. Designed by Baumgartner Environics, Olivia, MN the EPI (electrostatic particulate ionization) Air System discharges literally millions of negatively charged ions into the air space every second. These negative ions attract dust particles polarizing them to act like magnets and fastening to whatever surface they touch first.

“Yes, we are seeing lower dust levels and that’s appreciated by the pigs and the workers in the buildings. It also means fewer odor-carrying dust particles in the ventilation system,” noted Wayne. That lack of ‘hog barn’ odor is very noticeable to visitors.

Water conservation too

Water meters are also part of technology at their farm. “Being aware of water quality is a starting point in conservation farming, even as it pertains to your livestock. With these meters we are constantly monitoring our water. So if we notice any slowdown in pig performance we check the meters to see if there has been a drop off in water consumption. If that happens that’s a good indication of needing to take a closer look at the animals,” said Wayne.

A new tool for better water consumption is what’s called a fresh water trough. Yes, nipples are the traditional water source for most swine operations including the Dahls but they’ve added something new in their nursery. “What we have here is a water pan at floor level with water level controlled by a bladder that maintains constant water level. When you get 12 to 13-lb, 3-week old pigs newly weaned from their mothers, the first thing they want is a drink of water. But these metal nipple waters are totally new to them however they can see water in these pans and very quickly are drinking from them. Plus we’re told these pans reduce water wastage 20 to 30%. We’ve really seen an improvement.”

They’ve also switched from using chloride in their watering system to hydrogen peroxide. Using a product called Oxy Blast for treating nursery water, Wayne indicated it also reduces manure pit odors because the oxygenated water that drips from the nipple waterers produces an anaerobic environment in the pit below the slatted floors.

Also new is a simple in-line structured water filter device only about 12-inches long and as Wayne describes, “It’s just glass marbles that water passes through and the claim is that this process energizes the water which in turn means better water utilization within the pigs system.”

Cautious about claiming ‘scientific results’, Wayne simply stated. “Between the Oxy Blast system and this structured water we’re seeing our young pigs get off to a much better start.” He pointed out however there are so many variables in each group of pigs that it’s difficult to pin-point the success.

Their system revolves around 9 weeks for isoweans in the nursery facility and 18 weeks in the finishing barns. After each 9-week nursery timeframe, the entire structure gets a pressure washed, hot-water cleaning “….so it pretty much looks and smells like the inside of a car wash.” The same process happens after each cleanout of the finishing barns.

A farm for all ages

Wayne says the sparkly clean appearance of their hog operation is now typical industry wide of America’s pork producers. But it’s not all high-tech that drives the Dahl’s’ environmental stewardship. Much goes to simple things like keeping their farmstead comfortably clean and tremendously fun for their own grandchildren, neighboring kids, even classes from the local schools for a look at Laura’s incredible ‘petting zoo’ which includes an incredible variety of unique birds, chickens, pheasants, goats, geese, rabbits and a pair of adorable llamas.

“I’ve always loved animals. I remember as a little girl being so sensitive about my little pets. It’s my nature. I was born with it apparently. My pets are good therapy for me, for my friends, and especially for little children. My grandmother used to love her chickens. I grew to cherish her love for chickens. I even decorate my kitchen with chicken art work,” says this lady with an inexhaustible heart of love and sharing. “Grandparents love to bring their little grandchildren to our house,” she noted.

Wayne and his brother David team up to grow 1,800 acres of crops in a corn-soybean rotation. The Dahl’s youngest son Jordan who is also a professional wood carver is an integral farming partner. Also a neighboring young farmer, Tanner Winge, is a part-time assistant on the swine enterprise. “He’s just an exceptional young guy. I can’t say enough about his animal husbandry skills,” said Wayne.

Their family includes Tanya, age 34; Tera, 31; Terese Viessman, 29, with husband Nate and children Skylar, Walker and Tucker; Jarrett, 27 and Jordan, 25. Both sons have become skilled chain saw sculpturing talents with Jarrett winning 1st place in the 2012 Alaska Chain Saw Carving show.

About the National Environmental Steward Award

The National Pork Checkoff, along with its cosponsor, National Hog Farmer magazine, selected four pork farms to be honored as the 2012 National Pork Environmental Stewards. This year’s award recipients are: Dahl Family Farm, Dawson, MN; Future View Farm, Willow Street, PA; Trail’s End Sow Farm, Ames, Ok; Reed Family Farms, Ottumwa, IA.

The Environmental Steward award winners were selected by a panel represented by other hog farmers and environmental organizations. The committee reviewed applications from pork producers who are committed to upholding the ideal relationship between pork production and the environment. The applicants’ farms were evaluated on their manure management systems, water and soil conservation practices, odor-control strategies, farm aesthetics and neighbor relations, wildlife habitat promotion, innovative ideas used to protect the environment and an essay on environmental stewardship.

Veterinarians Searching Out Solutions for Swine Industry

EPI Air was on display at the Allen D. Lehman Swine Conference in St. Paul Minnesota’s River Centre, September 15th – 18th . Veterinarians from around the world gathered to review research work towards science-driven solutions to complex challenges facing the swine industry.

More than half of the visitors to the EPI Air booth had heard of EPI before.  We also received confirmation that veterinarians familiar with EPI technology are informing their inquiring clients that EPI technology is both science-based and makes sense. Several research veterinarians stopped by the booth as well, to touch base on on-going studies and soon-to-start studies involving EPI technology.

Several hypotheses are being tested to measure the impact toward better herd and worker health that cleaning the air provides. Of special note are studies that aim to measure the pathogen-killing effects of saturating the air with electrons, or antioxidants. These studies aim to confirm field observations of biologic activity against pathogens. The swine industry looks forward to having another tool to battle the PRRS virus, the influenza virus, mycoplasma and other diseases that may be limited through the use of EPI Air technology.

Clean Air at the Allen D. Lehman Swine Conference

Leaders from the swine industry across the globe will be coming to the beautiful state of Minnesota this weekend. They are coming not just to see the beautiful fall colors, but to attend an internationally acclaimed Swine Conference.  The Allen D. Lehman Swine Conference, put on by the University of Minnesota Veterinary Medicine’s continuing education program, will be at the St. Paul River Centre in St. Paul, Minnesota on Sept. 15-18, 2012.

swine conferenceAllen D. Lehman was a University of MN Extension Veterinarian who initiated the conference in 1974 to give practitioners a forum to discuss important issues in the swine industry.  Lehman worked to define the links between swine disease and swine production. After Lehman’s death in 1994, the conference was renamed in his honor for his dedication to education in practicing veterinarians. Today, hundreds of participants from over 20 countries attend.

This conference is a great place to discuss best practices, challenges, and the latest innovations in the swine industry. Besides the great conference and pre-conference programs and poster presentations, many of the attendees greatly value the networking that happens in the seminars, hallways, and exhibit hall.  The staff from Baumgartner Environics looks forward to talking with veterinarians and graduate students about swine disease, swine production, and how EPI Air offers solutions through cleaning the air of dust particles for marked improvement in animal growth and livability.

A Breath of Fresh Air

Brandi Buzzard

Recently, Brandi Buzzard, an Agricultural Communicator, Writer, and Scientist who works at Kansas State University, wrote about EPI Air Technology on SwineWeb.com in an article titled “Airing it Out”. At the Animal Science and Industry Department at Kansas State University some of her responsibilities were to coordinate and conduct research trials aimed at developing low stress production practices for swine and cattle producers. Brandi noted, “While I generally enjoy conducting research in swine barns, I must admit that I don’t enjoy what I unaffectionally call ‘hog barn crud’ or the hacking and coughing I experience for the next 2 days after being in the barns.”

What Brandi experienced is the same poor air quality in the barns that swine, poultry or other livestock livein each day. The employees that work in the enclosed swine facilities breathe in the excessive particulate matter in the air, which also contains high levels of ammonia. Needless to say, the dust, gases, and ammonia can be a concern to animals and humans alike. Brandi feels that EPI Air has great possibilities, “ I think it has huge potential to increase herd respiratory health as well as improve the working environment for employees.”

Another student at K-State Swine unit is currently conducting a study to evaluate the effectiveness of the EPI Air system. Although the study is still going on and the results are not available yet, it looks like a promising solution for swine producers. Brandi is excited to hear the results. She explains, “Well, for starters the amount of dust that is removed from the air is astounding. Seeing all that particulate matter stacked on inanimate objects like fences and the walls really opens your eyes to how much dust is flying around in the air and being ingested by both the employees and the animals. If they’re concerned at all about respiratory health for either, they’ll want to consider EPI.”

Brandi is passionate about agriculture and it shows. She writes about it on her blog and on Twitter. Agriculture employs both her family and her husband’s family, and as Brandi says, “It’s our way of life and all we’ve ever known.” Brandi’s philosophy is “I write and speak out and tell my story – if I can help one more person learn about agriculture, then I’ve done my job.”

Technology to the Rescue

By Dick Hagen, Hagen and Associates

Livestock producers are fully aware of the ‘big pain’ building in their cost accounting ledger. Feed prices, especially corn, keep escalating. On August 2, Chicago Board of Trade had September 12 futures for corn hovering around $8; September soybeans at $16.35. Chicago Mercantile meat futures were trading at $76.85 for October 12 hogs; cattle at $140.12.

The dilemma? Processors can’t ramp up prices enough to offset increasing production costs of producers without significant resistance from consumers. In essence, increasing meat prices at the retail counter inevitably generates shrinking sales. Rationing is setting in at all levels of the food chain, including pork producers.

Unfortunately no one has the ‘inside intelligence’ to predict how long the belt tightening will last, nor how severe the pain will become. So how do you survive the current squeeze, especially when it continues with such hour-by-hour volatility? Well, after you have answered the question: “How many of my barns will continue to have pigs in them?”, you need to reduce mortalities and improve feed efficiency.

EPI Air to the rescue? Murphy-Brown, LLC thinks so. Their results were solid. They tested EPI technology on 44,000 nursery pigs. Check these rather remarkable results:

  • Average daily gain increased 12.2%
  • Average weights increased by 9.3%
  • Mortalities were reduced by 26.1%

Workers in these Murphy-Brown facilities also appreciate the ‘cleaner air’ environment.

Here’s why: The EPI barns had a 55% reduction in ammonia versus the control barns; a 58.6% reduction in hydrogen sulfide.

Comments John Baumgartner, BEI President, “My question to pork producers is simply this: Is an investment that returns your money within 18 months a good investment? Murphy-Brown estimated their payback at half of that, 9 months. And that was before the drought. In today’s ‘crunch time’ economy with increased feed costs, those return-on-investment (ROI) calculations are even faster.”

Proof of the cost-effectiveness of EPI technology is Murphy-Brown going ‘system wide’ throughout their entire Western Division with EPI units. We’re talking 655,000 nursery spaces plus 864,000 wean-to-finish spaces.

Said Dr. Steve Pollmann, President, Murphy-Brown Western Division, “This is a significant step change in environmental systems. We’re excited. The science is sound. The take away is that EPI in our test runs provided documented evidence of the potential benefit of this technology.”

Sums up Baumgartner, “We think EPI technology is on the threshold of becoming ‘must have’ technology. Especially during these difficult times, improved performance is the key to sustainability and a quick ROI has always made business sense.”

Why Use EPI?

Leaders in the livestock industry are continually looking for ways to improve the performance of their livestock. Just like food and water, clean air is essential to an animal’s health. Improving in-barn air quality is now achievable with EPI Air Technology by Baumgartner Environics.

Here are some reasons to use EPI to improve air quality:

Improve Production

Nurseries who have used EPI Air have noted significant production gains. For instance, Murphy-Brown cited an increase of ADG by 12.2%, and an increase in weights of 9.3%.

Reduce Mortalities

Cleaner in-barn air quality leads to a reduction in livestock mortalities. Murphy-Brown reported a reduced mortality rate an astonishing 26.1%.

Reduce Barn Emissions

In-barn emissions are reduced in barns that use EPI Air. When Murphy-Brown tested the air quality in barns with EPI installed, compared to the control barns, there was a significant reduction in particulate matter, ammonia, hydrogen sulfide, and odor.

34 Week Return on Investment

On top of the environmental reasons to use this dust reduction system, EPI also makes economical sense. Murphy-Brown reported a quick, 34 week ROI with the EPI Air System, making it a must-have technology in their hog barns system-wide.

With results such as improved production, reduced mortalities, and reduced barn emissions, it is easy to see why improving in-barn air quality with EPI Air improves the overall performance of your livestock in a cost-effective way.

World Pork Expo is Super Showcase for BEI

By Dick Hagen, of Hagen and Associates

Perhaps speaking for the 400+ exhibitors at the 2012 World Pork Expo, Des Moines, John Baumgartner, President, Baumgartner Environics, Inc., Olivia, MN simply said, “Expo is the one-stop place for scientific and business information technology for the pork industry. And to a huge extent, this show is about people. Be that pork producers renewing acquaintances, technical people briefing on the latest issues and new products, and enjoying the atmosphere of international guests from everywhere. Expo truly is the celebration of the U.S. Pork industry and we were hugely satisfied and impressed with the traffic at our EPI-Air exhibit.”

Show-stealer for BEI was their unique display of the EPI (Electrostatic Particle Ionization) system in which participants slapped on a wrist band and decidedly felt the ‘tingle’ of electronic waves which capture airborne dust, ammonia, odor and hydrogen sulfide within hog production buildings. The net result of this ionization process is cleaner air or ‘EPI-Air’ which in turn results in faster gains, reduced mortalities, and slight improvements in feed efficiencies.

Commented Matt Baumgartner, general manager of BEI, “We first released the Murphy-Brown test data validating our EPI technology at the 2011 Expo. Since that time there has been quite a bit of industry talk about this data and our technology, precipitated because Murphy-Brown, North America’s largest hog producer, is now installing EPI units throughout their Western Division.”

World Pork Expo logo“We had 7, sometimes 8 of our own people at our Expo booth and often just simply couldn’t keep up with the questions and inquiries. That’s about as good as it gets. Expo literally was a home run for us, with the bases loaded.”

Dr. Gary Bradley, Research Coordinator, Murphy-Brown LLC, directed the trials of the EPI technology. Interviewed at the Pork Expo, he commented, “We were fortunate to be on the ground floor of this new technology. We were quite impressed with the performance results and thus our major move with the installation of EPI units in most of our nursery facilities.”

We were fortunate to be on the ground floor of this new technology. We were quite impressed with the performance results and thus our major move with the installation of EPI units in most of our nursery facilities.

Next move for Murphy-Brown is testing EPI units in growing/finishing facilities. “There are different dynamics with ventilation in larger barns. Humidity may be more of a factor relating to the efficacy of ionization of air in larger barns. So our work now relates to the impact of negative ions in a more humid environment,” says Bradley.

Could EPI technology possibly reduce the movement of PRRS virus? Bradley only ventured, “That might be a possibility. I don’t think the negative ions could eliminate the virus from the barn. However, combined with the overhead positioning of EPI units perhaps a portable unit used at floor level could be ‘zapping’ viruses after the wash down.”

He speculates there likely will be additional technology that branches off from the current EPI system. As a research scientist he’s more than willing and ready to further explore new ideas. “Preliminary results were phenomenal in our nursery units so we’re totally open to stretching our minds about a further spin off of EPI technology.”
