Main features

1.Highest Moisture and Dust Protection IP 65

EMC motors are IP65. In all ECM motors a conformal coating is applied to the electronic control board for complete moisture protection.


2.High safety class II

EMC motors with plastic housing parts and the protection level has achieved class II,Therefore the earth conductor will be unnecessary -and saves you a lot.


3.Constant Speed Control

Their smart electronics regulate voltage fluctuations so that the speed remains constant across a wide range of voltages and fan blades;it will help the cooling system work properly.


4.Reverse on start

Motor reverses on start when start-up through pre-set of the program,and keeps condenser coils clean-for long-lasting high cooling capacity.


5.Reverse on demand

Motor reverses demand when defrosts through pre-set of the program.and keeps the heat exchanger of condenser clean-for long-lasting high cooling capacity.


6.Two Speed Operation

The special performance feature of the two speeds is its two factory-programmed speed steps,reducing energy consuption.Typically used when the compressor is not operational or when night mode is engaged.
