Cool to below 1 Kelvin
Our 1K cryocoolers  are easy to interface with either a mechanical (GM/PT) precooler or the 4K plate of a 'wet' dewar using liquid cryogens. We can offer a number of interfacing options to accommodate a cold table housing the end-user experiment. Just contact us to discuss your requirements.
Customer applications for these cryocoolers coolers include quantum computing, single-photon detectors, superconducting electronics and semiconductor wafer testing.

Gram per gram, Helium 3 is the world's most expensive substance. CRC's gas-light sub-Kelvin crycoolers have been designed to make the best possible use of this scarce resource. By buffering the ultra-cold stage with either one or two intermediate stages, we reduce the heat load on the ultra-cold head and hence lower the running temperature and lengthen the run time. As sealed, closed cycle systems, no helium gas is consumed during operation and our units never need to be recharged or re-filled. Our latest design, the 300mK continuous cooler, even offers unlimited run time.

Cool to the max by using the latent heat of enthalpy produced as liquid Helium 3 dissolves in liquid Helium 4. Once again, our protoype dilution coolers are compact, closed cycle units that need no external gas supply and will never need to be refilled with expensive Helium 3. We are currently working with our R&D partners at Cardiff University's Astronomy Instrumentation Group to optimise the design and to explore the potential for continuous operation, by using our 300mK continuous cooler to buffer the dilution module. If you are interested in the potential applications for this cooling technology, get in touch with us to discuss your needs and how we might help.
