Geothermal pre-conditioning

The Geothermal pre-conditioning is a ground heat exchanger designed for use with heat recovery ventilation units. In cold winter seasons, the geothermal pre-conditioning prevents the ventilation unit's heat exchanger from freezing and becoming damaged. During hot summer periods, it cools incoming air, creating a comfortable indoor environment. The "GHT" units employs a geothermal heat collector to transfer heat from the ground to the air within the ventilation system.
