Dry Cryogenic Couplings
Dry Cryogenic Couplings are designed for use of cryogenic applications/medias such as LNG and Nitrogen and other liquefied gases.
The DCC coupling is suitable for the loading and unloading of cryogenic liquefied gases, such as LNG, nitrogen, oxygen, argon, ethylene, down to -196° C.
A quick and safe connection of hoses and loading arms under pressure and with minimized product loss. During the cool down phase no retightening of the connection is necessary as practiced with flanged or threaded connections.
Dry Cryogenic Couplings according to ISO 21593 and ISO TS 18683.
