Desert Master™ 50TJM
Desert Master™
50TJM
Single-Packaged Rooftop
Puron® (R-410A) Refrigerant
15.0 to 27.0 nominal tons
The 50TJM units are single side discharge rooftop cooling unit utilizing electric heat as an option. Units are prewired, pre-charged with R-410A 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.
Carrier’s Package Rooftop Unit software makes selecting and optimizing the 50TJM easy.
