Paramagnetic salts crystallised onto an inert high thermal conductivity mesh form the basis of CamCool's cryogenic salt pills. Various salts are used in different pills to fulfil specific requirements in the system of operation.
In a prototype ADR we have reached a base temperature of 38mK using a single salt pill to cool from 1.5K. Temperatures below 20mK have been achieved using a combination of two different salt pills in a double stage ADR.
CamCool salt pills are reliable and durable. Our test pills have lasted for more than 60 cooling cycles over a two-year period with no noticeable degradation of cooling power.
We can provide quality replacement paramagnetic salt pills for existing refrigeration systems to improve or restore performance.
