CSR - Product variants

CSR version for dry nitrogen

The CSR separation seal is also available for operation with very dry nitrogen with no limitations regarding dew point. Newly developed carbon ring materials ensure smooth operation even when the CSR is supplied with very pure nitrogen, from e.g. cryogenic production. The reliability of the system can be increased significantly as a result.
