48DJ Weathermaker II Rooftop Units Cooling with Gas Heat

20 to 27 Nominal Tons

Single-Package Rooftop Products Designed to Meet Commercial and Industrial Application Requirements

Features/Benefits

Design flexibility: Convertible unit design allows the factory built vertical unit to be easily converted to horizontal by installing 2 panels (accessory horizontal conversion package).

Gas heat: Aluminized steel gas heat exchanger is tubular design for low-pressure drop. Aluminized steel material ensures long life. Induced draft design maintains a negative pressure in the heat exchanger as a safety precaution to prevent any noxious fumes from mixing with supply air. Constant volume units have 2 stages of heat on low and high heat capacities. Units are built for use with natural gas. The heat exchanger is warranted for 5 years with an optional 6-10 year warranty available.

Unit efficiency: Dual serviceable, semi-hermetic compressors on intertwined evaporator coil ensures excellent full and part-load efficiency with EERs (Energy Efficiency Ratio) to 9.6. Dual refrigerant circuits provide standby capability should one circuit require service. Reliable 06D Carlyle compressors are proven performers.

Installation/serviceability: Small footprint requires less roof area and makes unit easier to rig. Low unit profile allows units to be mounted closer to edge of building while remaining out of public view. Up to 60% smaller volume than comparable units. Single-point electric and gas connections are standard on all units.
