Energy Recovery Option/Accessory for 2 to 12-1/2 Ton WeatherMaster® and WeatherMaker® Rooftop Units
1 to 5 Nominal Tons
The 62AQ units are single piece packaged modules designed specifically for 2 to 12-1/2 ton WeatherMaster or WeatherMaker units as a factory-installed option or as a field-installed accessory module. The 62AQ unit recovers energy from building exhaust air and pre-conditions the ventilation air in the cooling or heating mode using a specifically designed R-22 heat pump. When selected as a factory-installed option on an HJ or HE unit, the combined rooftop unit and 62AQ unit become a Cobra™ energy recovery unit.
