Cold traps

At inlet pressures below 1 mbar cold traps using dry ice or liquid nitrogen as coolant provide important protection for your pump by separating condensates and aggressive media. Cold traps using liquid nitrogen may be essential with very volatile solvents and reduce the back streaming of oil molecules into the vacuum system. Furthermore a cold trap will considerably increase the effective pumping speed for vapors.

Particles reduce the lifetime of the oil and increase service demands. The full-flow oil filters efficiently filter micro particles out of the oil. The service indicator helps to avoid unnecessary filter changes.
