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.
