Heat Exchangers
Heat exchangers offer you a fresh look at an energy
management tool that is dust free, freeze resistant and easily maintained.
You are able to bring fresh air into the barn and recover heat that
you would otherwise need to supplement.
 The
heat exchanger units feature a wash system, indoor & outdoor
drainage, removable core, variable speed control and automatic electronic
defrost.
