AFCryo Liquefiers

Truly modern technology that delivers long-term consistent performance and reliability.


AFCryo has the PTC90, PTC330 and PTC1000 cryocooler liquefiers available for commercial applications.
The benefits of the ruggedness and mechanical simplicity of the dual diaphragm pressure wave generator, integrated with the lack of moving parts of the large linear pulse tubes, combine to deliver a cryocooler ideally suited to the liquefaction and re-liquefaction of gases in industrial environments. It is particularly well suited to applications such as refrigeration of LIN for large HTS systems, LNG, liquid air, LOX and Hydrogen.

The systems are modular so can be sized to the client’s specific needs, with the added advantage of being upgradable at a later stage to a larger size.

The liquefiers include a fully integrated air-to-gas system comprising compressors, air separation, buffer tanks, dryers and filtration. The control system provides one button control of the complete air-to-liquid system, fully automated for remote operation.

All our systems can be delivered fully self-contained, which removes the need for sourcing additional components and cooling sources.
