WEKA Solutions for Loss-minimized Applications

Helium, hydrogen, oxygen and other gases are liquefied at temperatures well below 0°C and recovered in efficient recirculation systems. Valves are key components of every liquefier and are responsible for regulating parameters and maintaining the optimum operating point. The accuracy and stability of the control system have a significant influence on the efficiency of the plant. At the same time, cryogenic valves connect helium cryogenic lines to room temperature – this unavoidable heat influx must be minimized.

WEKA specializes in high-quality, reliable cryogenic components for fluid temperatures down to 2K (-271°C) – even where the process environment poses exceptional challenges.

Proven Solutions for Demanding Applications
 

  • Plants for liquefaction of helium and hydrogen
  • Air separation plants (ASU) for industrial gases
  • Gas recovery systems for loss minimization
  • Cryogenic cooling systems for superconductors
  • Scientific experiments with liquid gases
  • Reliquefiers for valuable gases

Expertise for Minimal Heat Input and Maximum Efficiency
WEKA valves of the TEV and TEQV series have a construction specifically developed for cryogenics, which minimizes heat input and increases plant efficiency. 
Transfer line couplings with small gaps and thin metal tubes ensure minimal thermal heat input despite the physical connection, and the BOG recirculation option ensures minimal losses.

Vacuum tightness is crucial for the insulation process of cryogenic plants. 
All WEKA components are manufactured and tested with highest quality to guarantee vacuum integrity at every pressure level.
