CXS - An introduction

Chemical processes present special challenges when it comes to vacuum. Equipment often has to operate in damp, dusty, corrosive, flammable or explosive environments.

Systemisation

CXS chemical dry pumps are available as stand-alone pumps or complete systems, including mechanical boosters for higher pumping capacities, and can be enhanced with a range of standard accessories such as valves, flame arresters, condensers, knock-out pots and filters.

Two models are available initially, the CXS160 and CXS250, which give nominal capacities of 160 m3h-1 and 250 m3h-1 respectively.
