In our series: Product lines in focus, we alternately present the most important features and characteristics of our product lines in short from.

In the field of cryogenics, today's topic is "transfer line couplings", which avoid heat input into cryogenic fluids as far as possible.

Task and function

Creating a separable connection between a vacuum box or vacuum container and a flexible transfer line.

Application areas

• Plasma and fusion research
• Hydrogen Infrastructure
• Helium and hydrogen liquefaction plants

Operating principle

The connection can be made or broken by operating a locking device (union nut or clamping ring).

Special suitability in the field of application

An optimized design guarantees the least possible heat input into the fluid and, thanks to a welded design, ensures maximum tightness to the outside and against vacuum.
