The Reznor’s Model RDCC Heating and Cooling Makeup Air Packaged Systems
Reznor’s RDCC (MAPS®IV) packaged rooftop units are designed to cool, dehumidify, and heat high volumes of outside air year round for makeup air and ventilation applications. In addition, MAPSIV can provide significant capacities of space conditioning. The MAPS IV series all leverage the use of modulating scroll compressor technology to maintain desired leaving conditions. Model RDCC units are designed to provide an average cooling supply air temperature of 50 to 55 degrees F in humid to temperate climates with superior gas heating modulation – up to 8:1 during winter operation.
Model RDCC units are designed to provide an average cooling supply air temperature of 50° to 55°F in humid to temperate climates.
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.
