Product Details

The Reznor’s Model RDC Cooling and Dehumidifying Makeup Air Packaged Systems
The MAPS®IV Series packaged rooftop units are designed to cool, dehumidify, and heat high volumes of out side air year round for makeup air and ventilation applications. In addition, MAPSIV can provide significant capacities of space conditioning. Model RDC units offer all these same features, but also include Reznor Re-Heat Pump™ dedicated reheat cycle. Re-heating of the air by this method saves over 4 to 5 times the energy used by electric heating elements. Additionally, the system is capable of maintaining reheat even when the demand for cooling and dehumidification is minimal. More importantly, this method of reheat complies with ASHRAE
Standard 90.1. 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.
