Aspro variable gas inlet pressure compressors work as a standard compressor or booster int he same product and are the ideal solution to cover the needs in regions where there is still no gas pipelines. This versatility allows to receive gas from a gas transport unit or from the gas pipeline network so as to supply a CNG refueling station in normal conditions, achieving the highest performance and power consumption.
- FROM GAS TRANSPORT UNIT
Inlet pressure: 250 to 14 bar / 3.625 to 203 PSI - FROM GAS PIPELINE
Inlet pressure: 9 to 60 bar / 130 to 870 PSI - Flow: 100 a 4000 Nm³/h/ 58.8 a 2354 SCF/m
- Horizontal reciprocating of 2 / 3 /4 / 5 stages
- Direct coulpling or driven belt transmission
- Electric motor
- Power: 45 / 110 / 132 kW ( 60 / 150 / 175 HP)
- Air cooled
- Lubrication system
