The reciprocating SICOM compressor, oil free type are the most important solution in the CNG field. SICOM design and manufacture compressor with simple or double effect head, with disposition of the cylinders to W or horizontal. In order to increase the compression phase performance and therefore to reduce the absorbed power, the SICOM compressor have an interstage cooling system water-gas type; SICOM produce also air-gas system. SICOM manufacture compressors with 2 or 3 cylinders from 3 or 4 phases. The compressor is drived by an electric or endothermic motor, direct coupling link, or through transmission straps. SICOM compressor model range is 2 to 2300 Smc/h of flow rate, 2,2 to 350 kW of installed power and 0.2 to 70 barg of inlet pressure

To the exit of the last stadium of compression, the cooled gas and filtrate is sent to a further hydraulic compressor (booster). This addictional compression unity is able to lift the gas pressure from 20/160 bar to 250 bar. The main characteristic of the hydraulic compressor is the lower rpm revolution motor; this permits a very slow refuelling phase, without increase the final gas temperature. The SICOM booster use electrical motor with range power: 7.5 to 75 kW and flow rate from 300 to 650 Smc/h. Discourse differently as refer the BV30, this unit is employed to discharge the cylinder trucks. It can work with suction pressures ranging from 5 to 200 bar and outlet pressure of up to 250bar with a maximum lead of 1500 Smc/h.

The SICOM "CNGBOX" is a "in box complete CNG station" for compressed natural gas CNG; the unit consist of: - structural container steel box - SICOM compressor model 680 directly coupled with electrical motor - electrical control panel - gas cooling system (air or water) - storage (if requested)

SICOM design and manufacture complete CNG filling stations for private or public use.
Every station is studied to find the optimal solutions based on the inlet gas conditions and the requested performances.
SICOM is able to define stations composed by several compression units, storage groups, distribution lines and dispenser to fill several vehicles per hour.
The wide range of alternative SICOM compressors permit to insert him in different gas conditions, available spaces and performances.
