Cryocoolers

A cryocooler is a mechanical device utilizing a refrigeration cycle, designed to cool an item to a temperature so low that ordinary gases become liquid.

Whilst many variations of cryocoolers are available, few systems can provide industrialized functionality. Our systems require very low maintenance and have the ability to run in harsh environments with no degradation to cooling performance over the life of the unit. This ensures continuous operation extending beyond 50,000 hours.

The dual diaphragm pressure wave generator with large linear pulse tubes delivers these attributes:

– Minimal setup requirements: plug in for liquid production in 20 minutes
– Scalable and modular: install a single unit into an existing system, configure multiple units or install a full liquefier system
– Efficient, cost-effective, reliable, continuous running
– Low maintenance: servicing at 40,000 hours – for uninterrupted supply
– Minimize or eliminate the need for third party supply and logistics
– Well-suited for use in remote locations

Fabrum Solutions and Absolut System, in collaboration with Callaghan Innovation, have been developing large pulse tube cryocoolers based on Callaghan Innovation’s patented diaphragm pressure wave generators (DPWG).

The pulse tube’s lack of moving parts, in combination with the DPWG’s metal diaphragms, produces a cost-effective, long life and robust cryocooler. The DPWG has had 15 years of development, resulting in a series of DPWGs ranging in input powers from 0.5 kW to 35kW that have been coupled to a variety of in-line and coaxial pulse tubes.

The PTC330 cryocooler is based on a new 330cc DPWG and produces 480W of cooling at 77K. The PTC1000 combines three such pulse tubes on a single 1000cc DPWG to produce 1500W at 77K.

Fabrum Solutions engaged Absolut System to design the linear pulse tube. This joint development cemented the business relationship, and ultimately the formation of AFCryo. Both the PTC330 and PTC1000 are now in commercial production as stand-alone cryocoolers, as well as being integrated into full liquefiers. For use with Nitrogen, Oxygen, Air, Hydrogen and Methane.

The cryocoolers can be supplied as a stand-alone unit or configured as a mini skid with a closed loop forced air water cooling system, storage dewar, as well as VSD (variable speed drive) and control system, ensuring the simplest integration requirements. Simply connect power and gas feed, and the system is complete. The control system provides fully automated liquid production, turning unit on and off as liquid is removed from the storage dewar.
