Our mission is to provide next-generation ventilation & cooling system designs.
Our parent company is Hershey Ag where “superior production systems” are a way of life. Created in 1980, this family business has since become a leader and specialist in the pork production industry.
Hershey Ag manages sow birthing production sites and oversees everything from semen delivery and breeding sows to birthing piglets and manure management.
Hershey Ag has been involved in the design and construction oversite of over 50 sow & piglet grow-out barns, including the first tunnel ventilated grow-out barn in Pennsylvania in 1991. All barns are new construction and designed to produce hogs in a contract production arrangement.
Piglet grow-out barns are a continuation of sow birthing barns production. From piglets to market, the ventilation demands of the pigs are constantly changing. That’s why our team of specialists visits each location weekly to adjust and fine-tune the ventilation systems so the pigs can continue to grow and reach their maximum potential. We are constantly learning as we work the systems
Being in operation for over 40 years has allowed Hershey Ag to witness the swine industry’s transition to power ventilated barns, which has ultimately led to healthier, higher production levels. Photos of our power ventilated sow barn can be seen here. Watch this video about our sow gestation barn.
Our experiences in livestock cooling and ventilation needs, plus our personal roles as livestock producers, allow us to relate to the needs of dairy producers.
At TunnelPlus, we not only design and create systems tailored to your needs, we also understand how to manage systems, our design and automation standards make running your system easy, flexible and worry free.
Research has shown that many losses – decreased milk production, pregnancy loss and even animal death – on the dairy farm are associated with heat stress. Eighty percent of our customers say they installed our systems to decrease and avoid those losses.
Dairy producers are starting to see the advantages of power ventilation systems. was designed as the superior ventilation system for Dairy Barns.
At TunnelPlus, we apply our understanding of good design and barn operations to give you the system you can count on for years to come – done the right way, the first time and made easy to operate.
We have developed more than 250 dairy ventilation systems in 17 states, setting the standard for the next generation of cow cooling. Our fully-automated systems help reduce heat stress and improve animal comfort, ultimately resulting in increased reproduction, and increased milk production. Whether it’s in your holding pen, over the freestalls or even over the bedded pack, we design a system around what you and your cows need.
