Description

Specifications

The “NPO “GKMP” LLC develops and produces vacuum chambers with embedded cryogenic screens. The latter can be cooled down with the help of liquid nitrogen or helium, as well as by cryogenic gas devices using the Gifford-McMahon closed cycle or a pulse tube. Flow-through cryogenic shrouds can be retrofitted with additional cryogenic tanks, nitrogen or helium liquefiers to ensure a non-stop operation 24/7. The selection of a proper cryogenic accessories of a vacuum chamber depends of actual application purpose of the Customer.

Cryogenic facility VU-180 is used to check the quality of parts, nodes, mechanisms and pieces, to check reliability of electronic devices and electronic components, to manage the quality of materials and coatings, etc.

Our experts will be happy to answer your questions.
