Applications

Our systems are adaptable and can be built to your bespoke requirements. We work with many industries and provide a diverse range of solutions.

Liquid Air
Industries that have relied on the older technology of compressed air tanks can now take advantage of the benefits of liquid air systems. Previously liquid air needed to be mixed on-site as there was no solution for on-site production, or reliable delivery of bottled liquid air. Our technology enables the safe zero-loss production of on-site liquid air. When coupled with CLSS breathing apparatus, operators can benefit from significant advantages:

  • High density (728:1), smaller units compared to compressed air systems
  • Two times the density of compressed air, resulting in extended operating times
  • Low operating pressures (70–125 PSI) compared to compressed air
  • Significant safety benefits
  • Heat stress mitigation by utilizing cooling from heat exchanger to reduce body heat

Liquid Oxygen
When operating in remote or challenging locations the ability to produce medical grade oxygen is a luxury. The AFCryo cryocooler technology ensures zero degradation of liquid output purity, and can be deployed with start up to liquid production time of less than 15 minutes.

  • Aviation breathing oxygen
  • Medical breathing oxygen
  • Welding and cutting
  • Recharging cylinders

Liquid Nitrogen
Having on-site liquid nitrogen production enables the ability to store high volumes of nitrogen in a compact liquid form. Simply re-introduce the liquid at ambient temperature to return to a gas for use. For medical and fertility applications the ability to generate liquid nitrogen and store or transport it as you require is under your control. The cost to produce the liquid utilizing the AFCryo cryocoolers is significantly less than the commercial cost of the delivered liquid.

  • Cryogenic health treatments
  • Fertility freezing
  • Blood sample freezing
  • Bulk storage for re-gasing:
    • Landing gear struts
    • Recharging cylinders
    • Aircraft and automotive tire inflation
    • High pressure missile tube recharge
    • Wheel and brake repair facility
  • Inert explosive vapors within fuel tanks
  • Sterilization and purging of wine bottles
  • Emergency power unit purge and test (F-16)
  • Optical device enclosures and dome lanterns
  • Industrial gas ‘on-site’ supply (stored as a liquid)

HTS
As superconducting applications are deployed into the field, users will have the same functional expectations as their other system - reliability, no degradation in performance, on-site low-tech servicing, and long run times between maintenance intervals. The AFCryo cryocoolers have been designed to fully meet these expectations of performance and functionality.

  • Small to large volume LN2 production and reliquification
  • Multi-staged cryocooling solution (multiple units connected for redundancy proofing)
  • Long run, low maintenance, industrialized solution
  • Used in power systems, cable, busbars, motors and generators

LNG
Increasing global regulations on methane emissions demand a mobile, rugged re-liquifying solution. The AFCryo products have been designed to be compatible with industry requirements.

  • Reliquification of methane boil-off during marine transportation
  • Maintenance cooling for distribution tanks
  • Scalability of units
  • 3kW to 15kW packages

Veterinary
Remote and often irregular demand for liquid nitrogen can be catered for with an on-site AFCryo nitrogen liquefier. Integrating world leading gas separation units with the AFCryo cryocoolers ensures we can size the unit to your requirements.

  • Biosecurity and disease prevention utilizing biological testing
  • Disease surveillance
  • Equine care
  • Herd management utilizing fertility freezing of semen
  • Ideal for remote locations where regular supply is difficult, costly or unreliable

Fertility
On-site production of liquid nitrogen removes the concern of supply reliability when working with high value products such as semen. A fully automated system that continuously supplies product means you can stay focussed on your work, whilst leaving the supply of essential cryogens to AFCryo.

  • Fertility clinics maintaining sperm and embryo storage – mitigating the risks around system failures, such as refrigeration securities in the preservation of valuable sperm and embryo samples.
  • The demand for cryocooling agents such as liquid nitrogen is a crucial component to IVF treatment.
  • Remote location on site supply of cryogen.
