Paratherm Corporation Paratherm™ HE Heat Transfer Fluid
Categories: Fluid

Material Notes: Paratherm HE® is a high flash and fire point heat transfer fluid. Engineered for higher thermal and oxidative stability, it is efficient and cost effective. Its greater purity allows it to strongly resist degradation while holding thermal properties and maintaining efficiency. This provides for low mainetance and solid performance over an extended operating life. Non-toxic, the HE fluid is safe to use and easy to dispose. It can be safely combined with spent lubricating oils and recycled locally.
