High-pressure compressors
Medium- and high-pressure reciprocating compressors from three specialist manufacturers – Reavell, JAB and Belliss & Morcom – for air, nitrogen, helium, CNG and biogas. KOMP-R helps you choose the right one and takes care of service.
Each manufacturer has its own field. Choose a brand to see its series – or describe your application and we will propose the best solution.
British manufacturer from Ipswich, now part of Ingersoll Rand. Compact 5200 and 5300 series, the industrial 5400 up to 414 bar and Gazpack packages for CNG and biogas.
Media
Family company J.A. Becker & Söhne from Germany, “Made in Germany”. Gas-tight compressors for nitrogen, helium and CNG, plus boosters that raise the pressure of existing compressed air.
Media
Series
British pioneer of oil-free reciprocating compressors from Birmingham, part of Ingersoll Rand. VH, VM and WH series for PET bottle blowing and processes where oil in the air is not allowed.

High pressure cannot be reached in a single step – the air would heat up to several hundred degrees. A reciprocating compressor therefore compresses it in several successive stages and cools it in between.

Final pressure
Number of stages
Idealised adiabatic calculation for air entering at 20 °C and cooled back to 20 °C between stages. Real values are lower thanks to cylinder cooling.
Each stage has a smaller cylinder than the one before. The pressure ratio per stage stays moderate, so valves, seals and pistons are under less stress.
Between stages a cooler removes the heat of compression. Cooler gas takes up less space, so the next stage needs less energy.
A booster does not draw from the atmosphere – it raises the pressure of already compressed air, e.g. from 7–10 to 40 bar. For PET lines it is the most economical route to high pressure.
For nitrogen, helium and CNG the crankcase is gas-tight so valuable or explosive gas cannot escape. Oil-free versions deliver air without oil for food, beverage and PET.
A standard industrial compressor stops at around 13 bar. Everything above is the domain of medium- and high-pressure reciprocating compressors.
Applications
Manufacturers
pressure [bar] · standard compressors
13–90 bar
90–414 bar
From bottle-blowing lines to ship engines – wherever pressures above 13 bar or special gases are required.
Preforms are blown with clean air at 25–40 bar. Oil-free compressors and boosters cut energy costs.
Starting and control air on ships and systems where robustness and long service life count.
Starting air for large diesel engines, back-up systems in power plants and switchgear operation.
Process gases, nitrogen for inerting and systems that must run continuously.
Process air and gases at medium pressures, often oil-free and precisely controlled.
