Product Details

The Reznor’s Model RECB Cooling Makeup Air Packaged Systems with Electric Heat
Reznor® packaged cooling and cooling makeup air systems are available in the third generation of the Modular Air Processing System (MAPS®III).

MAPSIII packaged direct expansion rooftops are designed to cool and heat high outside air year round for makeup air and ventilation applications. These rooftop systems include the same approaches to outside air treatment found in field engineered or split systems. All MAPSIII products feature the Reznor IQ digital controller to fully integrate all operation and external sensing into a stand-alone package or through native BacNet, into a building management system.

Model RECB includes an electric heat section in single and three stage options for high modulation and temperature rise to 90°F.
