WALcryo Cryogenic Quick Coupling

Advantages of WALcryo Cryogenic Quick Couplings

Cryogenic applications demand precision, safety and durability, particularly at extremely low temperatures down to -200°C and high working pressures up to 16 bar.

The WALcryo TT series quick couplings are engineered to meet these rigorous specifications, providing a leak-free, fast and secure connection for cryogenic media.

The key features and benefits of WALcryo cryogenic quick couplings are highlighted below.

Enhanced Safety and Leak Prevention

One of the most critical aspects of handling cryogenic gases is preventing leaks and ensuring operator safety.

WALcryo quick couplings feature advanced valve technology that prevents liquid gas escape during connection and disconnection.

Depending on the application, couplings are available with venting and/or shut-off valves, ensuring controlled flow of cryogenic media. Additionally, the couplings are oil- and grease-free, reducing contamination risk and making them suitable for a wide range of industrial and medical gas applications.

WALcryo couplings are used across multiple industries thanks to their precision engineering and robust construction:

  • Research & Development: Facilitate safe transfer of cryogenic gases in laboratory environments, such as superconductivity, material development and refining processes.
  • Recycling: Used in cryogenic processes for efficient shredding of tires, starters and composite materials.
  • Food Industry: Essential for cryogenic freezing of fresh fruits, meat, seafood and bakery products, ensuring seamless gas supply.
  • Medical Sector: Supports MRI cooling systems and cryogenic storage in advanced medical and research applications.

WALcryo couplings are designed to withstand extremely low temperatures while maintaining full functionality, even in the presence of ice formation.

The bayonet locking system allows simple plug-and-turn operation, eliminating the need for special tools and ensuring a secure connection. The durable stainless steel and polymer construction prevents damage from thermal expansion, providing long service life even under frequent use.

supply and receiving lines. Key features include:

  • Self-closing valves to prevent gas escape during disconnection.
  • Dust caps to protect against moisture and ice formation.
  • Torsion-free hose connections to minimize stress and extend service life.
  • Customizable configurations for a wide range of industrial applications.

WALcryo offers two primary coupling models: TT-009 and TT-013, each optimized for specific operational needs:

  • TT-009: Designed for handling small volumes of cryogenic media, with a nominal bore of 9 mm and maximum working pressure of 10 bar. Ideal for laboratory and indoor applications.
  • TT-013: Engineered for large-scale cryogenic transfer, featuring a 13 mm nominal bore and working pressure up to 16 bar. Suitable for outdoor and industrial applications with frequent filling cycles.

Conclusion

WALcryo cryogenic quick couplings provide an innovative and reliable solution for the safe and efficient connection and disconnection in cryogenic systems.

Their robust, leak-free design and use of high-quality materials ensure optimal performance even under the most extreme conditions. Advanced valve technology, easy plug-and-turn operation and maintenance-friendly construction make WALcryo couplings suitable for laboratories, recycling, the food industry and medical applications.

With multiple models and configurations available, there is always a suitable solution for both small- and large-scale operations. WALcryo couplings contribute to enhanced safety, process reliability and long service life across all cryogenic applications.
