Profile: Dynalene Heat Transfer Fluids supplies industrial heat transfer fluids, glycols, brines, potassium formate, secondary refrigerants and high performance coolant. Our special EGV formulation extends the life of liquid-ring vacuum pumps, allowing fast-seal fluid separation from unwanted hydrocarbon-based fluids for corrosion protection. Our dynalene HC is a water based heat transfer fluid engineered to deliver the desirable low-end temperature performance of synthetic organic and silicone-based fluids.
