Compatible with all standards

The versatile SI 2052 is suitable for replacement of some market standards drain pumps used in cassette type air-conditioning units up to 20 kW.

The centrifugal technology inside this pump is specifically designed for removing condensates continuously, in any kind of environment, with a very low sound level.

The single level detection unit can be used as a safety contact (NC) to cut off the air conditioning system compressor or a solenoid valve automatically.
