Download Company BrochuresThe Johnston Couplings (also called bayonet couplings or transfer line couplings) enable a separable connection between a vacuum box, or a vacuum container, and a flexible transfer line. The couplings have one or two fluid lines and are vacuum insulated.
Multi-couplings possess not just one, but two fluid lines. It is therefore possible to transport not just the cryogenic fluid, but also the arising boil-off gas in a coupling. Typically, the two conductors are surrounded by a joint vacuum insulation.
However, in the event of large temperature differences between the two fluid lines, both conductors can also be equipped with separate vacuum insulation.
General Technical Specifications:
- Pressure: ≤ 25 BAR
- Temperature: 4.2 to 323 K (-269 to +50°C)
- Nominal Diameter: 5mm to 11mm
