Paratherm MG, Paratherm LR and Paratherm CR
Paratherm MG, a specialty version of the MR (mid-range) heating/cooling fluid, is certified HT-1 food grade by the NSF (the designation that succeeds the retired USDA H-1 certification). It is recommended for processes operating from 0°C to 260°C. Another NSF HT-1-certified fluid, Paratherm LR, operates at lower temperatures, from –40°C to 204°C. Paratherm CR, developed for use down to –100°C, has a low viscosity that permits higher fluid turbulence, resulting in faster heat removal than silicone liquids or d-limonene-based fluids.

Paratherm CR cryogenic heat-transfer fluid
A replacement for silicone and d-limonene, Paratherm CR cryogenic heat-transfer fluid has an extremely low freeze point (below –120°C). The fluid's low 10-cP viscosity at –88°C (20 cP at –96°C) enables significant efficiency gains at lower temperatures. And unlike silicone-based fluids, the CR fluid poses no containment or cleanup issues. Typical applications for Paratherm CR  include fine-chemical processes, pharmaceutical active-ingredient production, secondary coolant systems, continuous process applications, lyophilizers and environmental test chambers.
