The VELCO line of cryopumps are available in sizes DN 250 to DN 1250 as standard.

​

The optimized design of the internal components and a powerful cooling system allow operation under challenging conditions, i.e., high gas loads and/or high thermal radiation exposure up to 350 °C.

​

Additionally, this combination enables long operating times without interruptions and minimizes regeneration time.

​

The housings, manufactured from stainless steel, for sizes DN 250 to DN 630 are welded as a single component. Larger housings are in two part and are assembled by flanging.

​

Depending on the application, optimized series offer above-average pumping capacity or pumping performance relative to the respective flange size. This allows for a reduction in the number of pumps required and thus cost savings.
