We offer a full range of cryogenic gases, applications expertise and specialist chilling and freezing equipment to help you to:

• create a cost effective cold environment.
• improve the quality of perishable goods.
• boost productivity in your manufacturing process.
• develop innovative solutions to the most challenging problems.

We also offer a full range of refrigerant products and services for mechanical refrigeration and can help you to select the most cost effective chilling or freezing process.

Industries

As a leading supplier of cryogenic gases we have a wealth of experience in creating cold environments for processes across a diverse set of industries including:

• Food and Beverage – liquid nitrogen, carbon dioxide and advanced food freezing equipment for rapid freezing of fresh food to maintain flavour and freshness. Dry ice blasting is used for powerful non-abrasive cleaning.
• Heat Treatment – liquid nitrogen for quenching tool steel to obtain a martensitic microstructure with high wear resistance.
• Fibre Optics – liquid nitrogen and helium for rapid cooling of superfine strands of optical fibre.
• Energy – liquid nitrogen for the core of high temperature superconductive (HTS) cables allowing five times more electricity to be conducted.
• Environment, Water and Waste – vacuum systems and liquid nitrogen for pipe freezing, cryo-grinding for environmentally friendly and economically viable recycling of tyres.
• General fabrication – liquid nitrogen for shrink fitting metal components to achieve a seamless fit.
• Construction – liquid nitrogen to freeze the ground and enable tunnelling without danger of collapse and also for cooling concrete and ensuring its integrity in major construction projects.
• Air conditioning – liquid nitrogen for freezing air conditioning pipework, allowing maintenance to be carried out without draining or refilling the service, minimising interruption to service.
• Healthcare – liquid nitrogen, cryoguns and training for cryogenic treatment of warts and skin lesions by nurses. Dry ice for transportation of blood plasma and transplant organs. Liquid nitrogen for cryogenic storage of stem cells. Liquid helium for the manufacture and servicing of MRIs.
• Agriculture – storage and transportation of semen by livestock breeders.
• Hospitality and Leisure – liquid nitrogen and liquid carbon dioxide for state-of-the-art special effects.

Services

• Tailored food chilling and freezing solutions – for greater production flexibility, increased yield  and lowest total cost of freezing whilst maintaining flavour and presentation.
• Cryogenic equipment - installation, training and maintenance services.
• Specialist services to MRI manufacturers and operators - on-site technicians to re-capture and recycle unused helium during the initial fill and a range of top-up MRI services to hospitals to lower cost and increase scanner availability.
• Total helium management – installation of the supply facility, management of deliveries, modelling the most cost effective use and installation of helium recovery systems to recycle vented helium.
• Specialist application training – training medical staff in the use of cryogenic liquid and cryoguns.
• Stage special effects – from working with the equipment manufacturers to training end-users in the handling of both cryogenic gas and equipment.
