Heat Recovery
Plate recuperators: Made of aluminum and adapted for a different pressure of 10000PA. The leakage rate between the two air streams is less than 1%.
A condensate tray with a threaded condensate drainage pipe is mounted on the extracted air side (optional on fresh air side).
A by-pass is available as an option for free cooling, for reducing or eliminating the antifreeze coil upstream of the recuperator or for preventing plate clogging during periods when heat recovery is not required.
Coils ( 3/8" and 5/8"): The coils consists of finned coils placed in the supply and exhaust air units. The supply coil complies with the specification for hot water heating coils and the exhaust coil complies with the specification for chilled water cooling coils.
Thermal wheels: They comprise an aluminum hygroscopic constant speed wheel driven by a heavy-duty belt.
The assembly is installed in a rail-mounted galvanized steel frame inside the unit.
A high performance seal provides tightness around the wheel surround and between the air inlet and the air outlet.
The thermal wheel is equipped with a purge section to enable continuous wheel cleaning.
