A “Keep it Simple” Solution for a Healthcare Facility

This is one of two similar units installed in a Medical Building in MN. The two straightforward
units were designed to provide economical ventilation and DX cooling. Because the exhaust air volume is greater than
the supply air volume, the heat exchanger alone is also able to provide a significant amount of heating—without consuming any fuel it warms the air from –25 °F up to 42 °F even while in frost control mode. To comply with the facility’s requirements, this unit was also ETL listed.

Performance Specification
