RM Modulating Condensing Units

Capable of Cooling 5 Zones

The new RM model remote modulating condensing units are the next generation of direct-expansion, cooling-only air conditioning units designed to run multiple cooling units (evaporators) with up to five independent zones.

Models are available in capacities of 24, 30 & 42,000 BTU/Hr. Total cooling unit capacity should be within 15% of the condensing unit capacity.

The RM Series' high-efficiency compressors deliver full capacity even under heavy loads. The newly designed, one-piece electrical box with 3' (1m) cable can be remote mounted simply by removing one screw.

Additional service ports have been added for ease of charging and servicing. The one-piece chassis/pan has two new drain locations. New style hold-down brackets secure all four corners and allow for easier installation and removal.

Capacities (BTU/hr) 24,000 - 30,000 - 42,000
Voltages 230V/60Hz/1 or 3 Phase - 220V/50Hz/1 Phase - 380V/50Hz/3 Phase - 460V/60Hz/3 Phase
Reverse cycle for cooling and heating No; cooling only
Cabin Controls SMX, Qht, or Q3
