CNG Booster VII

LINE CNG

Scroll Down

Maximum efficiency,
minimum emissions

The innovative Booster series CNG Booster VII can compress up to 250 bar of previously treated and filtered natural gas and biomethane. They are designed and developed for professional use due to their 4 compression stages and low RPM. The CNG Booster VII have a flow rate that can range from 330 to 750 l/min, providing a high-performance power range. The remote control panel, supplied with a 5-meter cable, provides all indications to operate in maximum safety. Included is the innovative Hyperfilter filter system with 2 molecular sieve cartridges.

Watch it closely

Simplicity comes as standard

Imagine having a compressor capable of great performance and endowed with extraordinary robustness. What would all this be without absolute simplicity in operating it? We believe that’s what innovation is for: to make it simpler.

And now for all the details

4-stage high pressure pumping unit for methane

Aluminum monoblock
Forced lubrication with low-pressure gear pump
Input filter
Pipes, fittings and nuts made of AISI 316 stainless steel
Intermediate condensate separators after the second and third stages
High-pressure final condensate separators
Safety pressure switch after each compression stage
Special cast iron cylinders with low roughness lapping
Forged aluminum connecting rods
Forged steel crankshaft
High flow valves for the first, second and third stage
Roller Bearings for intensive work
Hardened steel fourth stage with 6 special cast iron piston rings
Second and third stages with thrust pads to eliminate lateral forces on the pistons
Filter system Hyperfilter

Electric motor

One of the key parts of the compressor: the motor transfers motion to the pumping unit through the belt. A three-phase electric motor from 9 to 11 kW is available on this model.

Purification system Hyperfilter

Placed after the last compressor separator and before the pressure maintenance valve, the purification system Hyperfilter enables reliable treatment of the breathing air, according to DIN EN 12021¹ when using original filter cartridges. The separator present between the 2nd and 3rd stages of the purification circuit makes it possible to extract as much moisture as possible. The filtering capacity with inlet air at 20°C and 200 bar is 3,050 m³.

Frame

Open frame made for easy maintenance and transportability. Tilting motor carrier plate ensures constant V-belt tension. Protective casing made of thermo-formed material channels cooling air over the cylinders and inter-stage pipes, ensuring high compression efficiency.

Control console equipped with inter-stage pressure gauges, internal temperature indicator, presence and wrong phase sequence alarm, oil shortage alarm, and run stop and manual condensate drain controls allow easy compressor operation and maintenance. Made of steel with scratch-resistant powder coating in RAL 9005 black.
