CXS chemical dry vacuum pump 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. Whatever your process requirements, Edwards can provide an innovative and economic solution that is safe, flexible and reliable. Building on long experience of vacuum applications, the new CXS range provides all the advantages of dry pumps while setting new standards for reliability, performance, control and economy. CXS chemical dry pumps are ideally suited to even the harshest chemical and pharmaceutical processes and provide optimum performance in a wide range of applications, including distillation, drying, evaporation, reactor service, house vacuum, solvent recovery, sterilisation, fatty acid deodorisation and filtration.
