SINGLE FLUID HEATING/COOLING
Paratherm™ MR Heat Transfer Fluid is a mid-range heat transfer fluid rated for service from 36°F to 550°F. It is efficient across the temperature range, thermally stable and cost-effective. Our mid-range thermal fluid is NSF HT-1 certified for food-grade applications. Used or contaminated fluid can be safely combined with spent lubricating oils and recycled locally. Paratherm MR heat transfer fluid is designed for a broad variety of applications such as batch reactors, laminating lines and plastics mold temperature control. It is engineered to provide outstanding performance under demanding conditions.
The lower a heat transfer fluid’s viscosity, the less energy will be required to pump it through the system. Paratherm MR fluid’s viscosity is among the lowest of available heat/cool fluids. This and the fluid’s exceptionally low-pressure drop means that less horsepower is needed for a given duty and that a smaller pump and motor can be specified. And, lower power consumption continues to produce savings year after year.

Paratherm MR Heat Transfer Fluid is plant friendly and safe to use. In the event of a release, the same simple clean-up procedures used for spills of light lubricating oils can be employed. Recovered fluid can be combined with spent lube oils and sent to the local oil recycler. Paratherm MR is a high purity, water-white fluid and contains no SARA-reportable substances, such as chlorinated hydrocarbons, aromatics, heavy metals, or sulfur or nitrogen compounds.
Unlike other heat/cool liquids, the MR fluid emits no pungent or noxious odors. See the Material Safety Data Sheet (SDS) before using this product.
Paratherm MR Heat Transfer Fluid has an extraordinarily low vapor pressure — a fraction of an atmosphere at its maximum operating temperature of 550°F. This permits the designer considerable latitude in the choice of lower-cost equipment that does not need to be pressurized to prevent fluid boiling and pump cavitation.

* These are typical laboratory values, and are not guaranteed for all samples.
** Note: Normal practice is to size expansion tanks so that they are
1/4 to 1/3 full when the system is cold, and 2/3 to 3/4 full when the system is at the maximum normal operating temperature.
