Dewar vessels

APPLICATION

Cryogenic vessels SK-16, SK-25, SK-40 (See Figure attached) are applied for the storage and transportation of cryoproducts: nitrogen, oxygen and air.

Design and operation principle

Cryogenic vessel (Fig.1) is a reservoir “vessel in vessel” where inter-wall space is filled by the multilayer isolation and is pumped by the at the manufacture till the residual pressure 133х10^-4 Pa (1х10^-4 mm of mercury)
