The AVI35 hybrid heat exchanger is designed to recover heat energy from the exhaust ventilation only when it is most profitable to the grower.
In the summer, when more exhaust is desired, one can easily remove the heat exchange cartridge and install the set of louvers in the service door to prevent backdrafts entering the barn.
Finally, once the spout is removed and the air intake fan's rotation is reversed, the AVI35 is quickly converted to a full exhaust ventilation system, where each fan has its own set point.
