Dewar & Ranger service and repair
We provide specialized Dewar and Ranger service and repair for equipment operating with cryogenic fluids, ensuring safe operation, reliability and compliance throughout the equipment lifecycle.
Our technicians have extensive experience working with cryogenic vessels and pressure equipment, delivering professional support for both routine servicing and corrective interventions on Dewars and Ranger systems.
Scope of service
Technical inspection of Dewars and Ranger vessels
Equipment diagnosis, including performance and operational assessment
Repair and replacement of valves, regulators and auxiliary components
Leak testing of the inner vessel
Functional testing after service or repair
Preparation of equipment for inspection and T-PED certification
Our services are designed to extend equipment service life, reduce unplanned downtime and ensure continued safe operation of cryogenic systems.
Leak detection
We offer advanced helium leak detection services for cryogenic and vacuum systems, using helium as a tracer gas, the most reliable method for detecting leaks in high-integrity installations.
Our high-sensitivity helium leak detectors allow precise localization of micro-leaks in:
Cryogenic vessels and pressure vessels
Dewars and Ranger containers
Vacuum insulated piping
Welded joints, valves and flanges
Systems operating with liquid oxygen (LOX), liquid nitrogen (LIN), helium, argon and LNG
Benefits of helium leak detection
Extremely high sensitivity for micro-leak detection
Accurate and repeatable results
Non-contaminating method
Suitable for cryogenic, vacuum and LNG applications
Supports preparation for inspection and T-PED certification
Early leak detection is essential to prevent product losses, safety risks and performance degradation in critical cryogenic installations.
Vacuum recovery
Loss of vacuum significantly impacts the thermal performance and efficiency of vacuum insulated piping and cryogenic vessels. After leak detection, vacuum diagnosis, or in long-running equipment, restoring proper vacuum levels is often essential.
We perform vacuum recovery services using our own dedicated vacuum pumps, specifically selected for cryogenic applications. Based on the results of leak detection, vacuum level diagnosis, or long-term operation of the equipment, we can support clients by restoring and stabilizing vacuum conditions, ensuring optimal insulation performance and full process control.
Vacuum recovery services include.
Vacuum recovery for cryogenic vessels
Vacuum recovery for vacuum insulated piping
Removal of moisture and residual gases
Restoration of optimal insulation vacuum levels
Final vacuum level verification and documentation
This service is critical for maintaining efficiency, reducing boil-off and ensuring reliable operation in cryogenic systems.
Maintenance and assessment
We provide comprehensive maintenance and technical assessment services for cryogenic systems, focused on safety, compliance and long-term operational reliability.
Our maintenance capabilities include specialized stainless steel welding suitable for cryogenic temperatures, ensuring the structural integrity of vessels and components and compliance with applicable regulations and standards.
Maintenance and assessment services include.
Technical inspection of cryogenic vessels and Dewars
Vacuum level inspection and condition assessment
Evaluation of vacuum insulated piping
Structural integrity assessment of pressure vessels
Preventive maintenance and condition monitoring
Inspection and certification support
We support and prepare equipment for inspection and T-PED certification, ensuring that cryogenic pressure equipment meets current regulatory and technical requirements.
A structured maintenance approach helps to:
Reduce operational and safety risks
Prevent unplanned shutdowns
Optimize cryogenic system performance
Extend the service life of critical equipment
