我们的2 k冰箱可以使用cool any conventional superconductor application in conditions where their performance is maximised, around 2K.
Our refrigeration systems are intended for research centres using superconductors and operating them at a temperature where the helium is superfluid (around 2 K) for their particle accelerator experiments, and they are specially designed to meet the requirements of customer applications. They include the helium refrigerator capable of delivering helium in the form required at 4.5 K, a supercritical liquid for supply to the user application such as magnets, and reducing the temperature of the helium to 2 K or 1.8 K by pumping the helium so that it reaches the necessary pressure of 30 mbars abs. or 15 mbars abs. as appropriate. Our refrigerators are also capable of supplying the necessary concomitant refrigeration at intermediate temperatures (80 K screening etc.). They can also include the fluid storage and distribution systems and the purification systems if necessary.
Key benefits
High performance: optimally efficient tailor-made systems that can reduce operating costs
Reduced maintenance: through the choice of highly reliable components that require less maintenance
Smaller operating teams: automation means that units can work on standard daytime timetables and not in shifts (3-shift system, etc.)
