Expo launches the most comprehensive range of inert gas buffer systems on the market


Setting a new standard for API 618 buffer systems

Inert gas buffer systems are essential to the safe and efficient operation of reciprocating compressors for flammable and other hazardous process gas service.

Expo have developed a standard platform that can be configured to suit any arrangement of compressor distance pieces, with capacity to supply buffer gas to up to 10 cylinders. With our experience gained from more than 9,000 purge and pressurization systems for large electric machines, our buffer systems deliver superior pressure control and simpler integration into your compressor control system.
