NTENDED USE
Dry Cryogenic Couplings (DCCs) are designed for use wherever it is necessary to connect and disconnect
hoses and pipelines under moderate pressure, quickly and without spillage. They are designed primarily for
use with cryogenics where reliability and safety are of prime concern.
All MannTek products are designed for trouble free operation in a wide range of applications and operating
conditions. Reliable and safe operation is dependent upon the correct installation and handling of the
equipment. Regular and appropriate maintenance is essential to ensure both safety and reliability over the
life of the equipment. Take care that the product is only used inside the limits of the following product
specification.
Operation is single action (see chapter 5.4), using a straight forward turning motion to connect the couplings
and open a flow path. An initial push and turn action on the hose unit causes engagement with the tank unit,
thus locking and sealing the two units together. Further rotation causes the internal valves to open, thereby
allowing flow with minimum pressure drop.
The connection and valve mechanism is interlocked such that fully engaging and sealing the hose unit on its
matching tank unit can only open the valve. On disconnection the valve fully close before the coupling
separate and spillage therefore is negligible.
