Quality and safety testing
Our rigid transfer lines are CE-marked and manufactured in full compliance with the EN-13480 standard for metallic industrial piping, delivering vacuum-jacketed, low-heat-leak transfer of cryogenic fluids. Each unit is certified to PED 2014/68/EU and undergoes mandatory EC Unit Verification by an independent Notified Body, ensuring adherence to the EU’s safety regulations for hazardous fluids and high-pressure systems. To ensure operational integrity and safety, every rigid transfer line undergoes:
-
Functional product testing: Validation of system operability.
-
PED compliance tests: Verification of conformity with PED 2014/68/EU requirements.
-
Internal compliance tests: Integrity validation through helium leak detection and other internal assessments.
Support and services
For those in need of additional support, we offer the following support options. Our team is ready to assist you with a safe and efficient integration into your set-up.
Engineering & system integration
We integrate our system within your exsting infrastructure to ensure optimal functionality.

Commissioning & operator guidance
We ensure that the system operates correctly at your location. Additionally, we can provide comprehensive training for personnel on safe system operation, including proper usage, hazard awareness, emergency procedures, and adherence to safety standards.

On-site installation
We perform an installation service by handling site preparation, equipment placement, and site acceptance testing. This approach guarantees safe and compliant integration into your facility.

Maintenance
We perform maintenance on the system to ensure reliable, safe, and efficient operation throughout its operational life.

On-site repairs
We perform a repair service to resolve equipment issues and to restore nominal operation. Certified technicians perform troubleshooting, component replacement, and system testing.
