• SIVL (Super-Insulated Vacuum Lines) / Vacuum Insulated Pipework Vacuum jacketed piping systems for transporting cryogenic liquids and gases (liquid nitrogen, helium, hydrogen) at ultra-low temperatures, minimising heat ingress and boil-off losses. Proprietary bayonet design eliminates vacuum joints on site and ensures a 5-year vacuum guarantee.
• Servicing, Preventative Maintenance and Safety Inspections Comprehensive service and maintenance for cooling, pumping and conditioning equipment worldwide, including F-Gas compliance services, system analysis, performance optimisation, refrigerant blending, and spare parts supply.
• Engineering Design, Analysis and Product Development Services Full-service engineering design and analysis capabilities including mechanical (2D/3D) and electrical design, CFD and finite element analysis, in-house analysis tools, prototyping and testing, and turnkey product delivery from concept to production.
• Precision Engineering (CNC and Manual Milling / Turning) In-house precision engineering workshop equipped with CNC and manual milling and turning equipment, serving cryogenics, marine, architectural and industrial sectors for over 30 years. Operated through Ashbrook Engineering.
• Valves, Pressure Regulators, Relief Devices and Instrumentation Supplied through Gas and Liquid Controls Ltd (part of GRE group), offering cryogenic valves, pressure regulators, pipe and fittings from manufacturers including Stohr, Pressure Tech and SSP.
• Fortis Chiller Range Chiller product line for vacuum deposition and industrial applications, featuring hermetically sealed scroll compressors, brazed heat exchangers, custom control platforms, and fully welded stainless-steel circuits.
• Fortis V-Chill Auto-Cascade Cryo-Chillers Auto-cascade cryo-chillers for achieving very low temperatures in industrial processes.
• AXipasteuriser Pasteurisation machines for human milk banks, featuring fully automated temperature control from ambient to 62.5°C with precision chilling to below 4.0°C, with temperature logging and adaptability for various bottle manufacturers.

Direct peers

• Cryostar (Air Liquide): Subsidiary of Air Liquide specialising in cryogenic pumps, turbo expanders, and refrigeration systems for industrial gas, LNG, and scientific applications. Closest direct peer to GRE in bespoke cryogenic cooling systems and turbo-Brayton/cascade refrigeration for low-temperature applications.
• Nikkiso Cryogenic Solutions: Division of Japan's Nikkiso Group (formerly Cryogenic Industries) supplying cryogenic pumps, LNG cargo pumps, and cryogenic process equipment. Comparable to GRE in custom-engineered cryogenic systems for research, fusion-adjacent, and industrial gas customers.
• Cryoquip: Specialist manufacturer of cryogenic vaporisers, vacuum insulated pipework, and LNG equipment. Direct peer in SIVL technology and small-scale bespoke cryogenic distribution systems, serving similar industrial gas and scientific research customers.

Emerging players

• Stirling Cryogenics: Specialist in Stirling-cycle cryogenic refrigerators and coolers for industrial gas, semiconductor, and research applications. Comparable to GRE's cryogenic product line, particularly for small-scale cryogenic cooling and LN2 production where Stirling technology competes with GRE's auto-cascade approach.
• Haskris Company: US-based specialist in water-cooled and air-cooled process chillers for industrial, medical imaging, and laboratory applications. Comparable to GRE's process chiller business for MRI, laboratory, and industrial process cooling in a similar mid-size niche.

Broad incumbents

• Chart Industries: US-listed manufacturer of cryogenic equipment, heat exchangers, and process technologies serving LNG, industrial gas, energy, and biomedical markets. Direct competitor in vacuum insulated pipework, cryostats, and process cooling systems, with a much broader product portfolio and global footprint.
• Mayekawa: Japanese industrial refrigeration specialist producing ammonia and CO2 compressor systems, chillers, and heat pumps for food processing, cold storage, and industrial cooling. Comparable to GRE in bespoke industrial chillers and process refrigeration, with deeper standard product lines.
• Trane Technologies: Global HVAC and refrigeration major producing chillers, heat pumps, and process cooling systems. Overlaps with GRE on the process chiller side (Fortis range competes with Trane/Carrier chillers) but operates at vastly larger scale across standard commercial segments.
• Linde Engineering: Global industrial gases and engineering division of Linde plc, designing and supplying cryogenic air separation, hydrogen, and natural gas processing plants. Overlaps with GRE in bespoke cryogenic systems, vacuum insulated pipework, and process cooling for industrial/research applications, though at much larger scale and broader scope.
