Oilfree Screw Compressor : DSP Series (132kW - 240kW) : Features

High Efficiency

Further Energy-Saving

Energy-saving operation control (Patent pending)

Surplus power is reduced by decreasing cut out pressure automatically, depending on compressor load ratio. For example, 160kW model enables a cut in power of approx. 33,600kwh/year under a load of ratio 40% and 67,200kwh/year under a load ratio of 90%.
(Based on 8,000 hours operation per year using 6m³ receiver tank)

Main Function

Noise Reduction

Lower in-class noise level

Improved vibration control construction in the drive system succeeds in reducing solid propagation noise and intake exhaust noise. Overall noise level is considerably reduced even compared with the same class of water-cooled model.

Greater Reliability and Easier Maintenance

Equipped with 4-pole TEFC motor as standard feature

4-pole TEFC motor (low frequency) as standard feature to improve reliability.

High precooler system (Hitachi patent)

High precooler with two stage cooling construction reduces hitgh inlet temperature before aftercooler.

Easier maintenance

Maintenance work such as filter exchange and cooler cleaning are now more efficient.
