The hot solution for cooler climates and extreme conditions

Unique, simple and economical - PSH scroll compressors series
The PSH 20-40 kW range is the simple, compact, energy-efficient and economical solution for R410A commercial heat pumps with system reliability, fewer components and reduced downtime.

From innovation to benefit

The liquid injection solution extends the compressor envelope to extreme operating conditions and reduces the applied cost on the system.
The PSH Operating Control System (OCS) provides full compressor protection and higher system reliability. The OCS reduces downtime and cuts system warranty costs.

Innovative liquid injection offers new possibilities within the heating market.

Extended operating envelope

In comparison to gas or oil furnaces for space heating and Hot Sanitary Water (HSW) production, a heat pump system offers very large energy savings up to 50%. But until now, most heat pumps were limited in operating temperatures.

The unique liquid injection solution extends the compressor envelope to extreme operating conditions and reduces the applied costs on the system. Heat pump and air conditioning manufacturers will be able to use the compressor with very high condensing temperature up to 65°C and at the same time with low evaporating temperature down to -30°C. The liquid injection solution is completely integrated in the compressor and requires only an additional ¼ inch pipe connection for the liquid coming out of the condenser. The compressor is easily integrated in a system and there is no need for any additional components. Thanks to the liquid injection, the Danfoss Scrolls, PSH, will open new markets like commercial heat pumps or air conditioning applications for extreme operating temperatures.
