Wherever vacuum pumps are used, they can soon become contaminated by water vapour due the the action of the compression cycle, necessitating regular oil changes to keep them operating efficiently and preventing premature failure.

If for instance they are used with vacuum ovens, resin casting systems, or similar situations, other volatile chemicals such as solvents and process chemistry coming from the process will also further contaminate the vacuum pumps oil.

This would usually mean regular replacement of both the oil and seals affording costly maintenance down times and running costs!

The solution would be to place a refrigerated vacuum trap before the pump, the trap which runs at a temperature -90°C will then condense out any moisture and vapourised contaminants, to improve both the vacuum and vastly extend the life of the vacuum pump and it's service intervals.

The basic overview of the system is a stainless steel vacuum chamber trap which is cooled to a level of -90°C by a cascading refrigeration unit.

As the vacuum begins to be pulled down, water vapour is released from the air which then freezes against the walls of the trap in the form of ice. As the vacuum is then further pulled down to operational values any contaminates developed from the process is then frozen on top of the ice already formed.

Once the operation is completed the chamber lid can be removed and the waste removed as a frozen mass or allowed to heat up the atmospheric temperature and drained away.
