Cryopump Revisions

To ensure smooth and seamless operation of our cryopumps, we recommend revisions at regular intervals:

  • After 15,000 operating hours, revision of the cold head and the inner parts of the cryopump
  • After 30,000 operating hours, revision of the compressor and replacement of the adsorber

If you plan your revisions well in advance, we can send you a loan pump to prevent any interruptions in production. Failure to adhere to the revision intervals may result in unnecessary disruptions. In such cases, we are always motivated to find a quick replacement solution for the customer.

A complete revision in our workshop consists of the following:

Cold head

    • Input power test on the test bench
    • Cleaning of all inside parts
    • If necessary, reworking of the machine tube for stage 1 and stage 2 inside
