Variable Speed ECM Condenser Fan Motors | HVAC Refrigeration

Variable Speed ECM Condenser Fan Motors are used in condensers for the high efficient models so that the fan speed for the condenser can be modulated according to the load of the system. The ECM variable speed fan motors are used in condensers that have a modulating compressor. They are also used in condensers that have two compressors or a two-stage compressor. The ECM motor adds to the efficiency of the system by modulating the condenser fan motor. The speed matches the compressor that runs based on demand. (more…)
