The Cryogenic Break-Away Coupling (CBC) acts as a safety
component in the supply line of mobile systems, preventing damage to
personnel and environment, instead of a supply hose or pipe rupture
during filling or emptying due to a change in location of the tank. The
coupling valves on the tank and on the supply line immediately close
whenever the CBC halves separates.
The CBC is specially designed for trouble free operation in cryogenic
service conditions down to -196ºC. 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.
There are two kinds of CBCs available. A marine type version is designed for offshore applications. The specific design
requires an installation between two hoses. It is only possible to release the coupling by axial force.
The length of the hose segments should not be less
than L=a/57,3 x (r+d/2).
L = min. required hose length
a = max. bending angle
r = min. bending radius
d = outer hose diameter
Figure 1: min. required hose length depending on bending
angle shown for hoses according to EN12115
The second CBC type is an industrial version. Regularly it is connected to a tank or a fix connection point inside a
loading station on one side and a hose or a loading arm on the other side. This makes that the CBC can be released
under a pull force angle up to 90º.
