HS. series

Nominal diameters (DN) are not actual dimensions!

The nominal diameters DN10 .. DN200 only indicate ranges! The number is not a quantifiable unit, it is only indirectly related to the diameters of the connections and should not be used in calculations.

Bushes / flanges and shut-off valves for HS. compressors. The designations and attributions correspond to those in the Bitzer price list.
HP: high pressure side / discharge gas side
LP: low pressure side / suction side
