Dedicated Vertical or Horizontal
Make Up Outdoor Air Units
with Puron® Refrigerant (R-410A)
6 to 35 Nominal Tons
|
 |
 |
|
The 62D Series make up outdoor air units utilize highly efficient scroll compressors that have been optimally designed for use with Puron® refrigerant (R-410A). Operating efficiency of the units may be increased by adding the optional energy recovery system. The 62D Series units are designed to meet customer requirements for new construction, replacement opportunities, and special applications. A wide variety of heating options are available with the units, which are tested in both cooling and heating modes at the factory.
