Setting a new standard
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.
- 3 core designs meeting the requirements for compressors withType C and D distance pieces
- Expandable, modular output construction for compressors with up to 10 cylinders
- ATEX & IECEx hazardous area certification for electrical and mechanical systems
- Integration into wider compressor control systems
- Comprehensive options including:
- Low buffer gas pressure alarm
- Sour gas (High H2S content) protection
- Hazardous area pressure transmitters
- Output line non-return valves
