Screw compressor SCR-22/7PM power 22 kW, pressure 7 bar, FAD 222 Nm³/h

Lossless direct drive 1:1

The SCR-PM series compressors are equipped with highly efficient ALLY WIN airends, which were designed in Germany and have several international patents. The screw block is connected directly to the main electric motor by means of a bevel joint, so there are no losses in the transmission.

PM motor with IE4 efficiency

The SCR-PM series brings the latest in oil-lubricated permanent magnet motor technology to the world of small screw compressors. The used PM motors, due to their design, have an extreme efficiency that exceeds the IE4 efficiency requirements of IEC EN 60034 and exceeds the conventional IE2 efficiency motors used as a standard solution for variable speed compressors by an average of 5%. In addition, the design of the PM motor does not contain any bearings, which eliminates the aspect of motor maintenance.

Speed control by frequency converter

Thanks to the speed control by frequency converter, there are significant savings, especially due to the elimination of no-load operation and the ability to adjust the output pressure from the compressor.

Speed control fan

The SCR-PM compressors have a second frequency converter to control the speed of the cooling fan motor. In addition to saving energy, SCR-PM compressors can operate at temperatures up to +45 °C and with very low outlet air temperatures.

Pipes instead of hoses

On the SCR-PM compressors, you will only find metal pipes instead of traditional flexible hoses. This saves you on future hose replacements and eliminates the risk of hose rupture and subsequent air or oil leakage as much as possible.

Efficient oil separation

Thanks to the three-stage oil separation by means of centrifugal force, gravity and a separation filter, the compressed air with an oil content of <3 ppm is treated at the outlet of the compressor.
