Product Details

The Reznor’s Model REDC Cooling/Dehumidifying Makeup Air Systems with Electric Heat
Reznor® packaged cooling and cooling/reheat pumpTM makeup air systems are available in the fourth generation of the Modular Air Processing System (MAPS®IV).

Model REDC packaged direct expansion rooftops are designed to cool, dehumidify, and heat high amounts of 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 MAPSIV 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 REDC also offers the additional feature of a dedicated Re-Heat Pump™ maintains dehumidification even when the demand for cooling is minimal. And, more importantly, it complies with ASHRAE Standard 90.1, Paragraph 3.3.
