In the chemical and petrochemical sectors, Keepwin gas compressor operate safely at extreme pressure and temperatures, handling a wide range of light and heavy speical gases, many with corrosive gas, flammable gas, toxic gas, bio-hazardous gas components.


The oil and gas industries extract and transport fluids in exceptionally challenging environments involving extreme highs and lows of temperature,high humidity and salinity and remote locations both on and offshore. KEEPWIN Reciprocating Compressor robustness and reliability is a vital part of the supply chain.


Many situations, including high presssure filling of gas cylinders and tubes, pressurising gas cartridges for airbags, and the manufacture and processing of ultra-high purity, rare gas and electronic gases, require that the gases must be hermetically isolated from the atmosphere to prevent fire hazard, contamination or pollution. Keepwin diaphragm compressor compressors are the optimum choice for such applications.
