Desert Master™ 50TJ
Desert Master™
50TJ
Single-Packaged Rooftop
Electric Cooling Units
HCFC R-22 Refrigerant
15.0 to 30.0 Nominal Tons
The 50TJ units are single side discharge rooftop cooling unit utilizing electric heat as an option. Units are prewired, pre-charged with R22 refrigerant, and tested at the factory. These units can be placed on the side of a building or can be placed on a roof without roof curbs. Each unit is designed to occupy a minimal space. Piping and drain connections are readily accessible.
