48PG CENTURION™

Single-Package Rooftop
Ultra-High Efficiency
Gas Heating/Electric Cooling Units
2 to 12.5 Nominal Tons


HVAC Equipment 48PG Centurion Rooftop Unit

48PG units are single-package ultra high efficient electric cooling with gas heating rooftop units. These units provide industry-leading operating efficiencies, ease of maintenance, installability, and reliability. Units come pre-wired and pre-charged with Puron® (R-410A) environmentally sound refrigerant at the factory. Units are factory tested in both heating and cooling modes.
