Which Type of Heat Transfer Fluid Should I Use?
September 10, 2019
CORECHEM carries four types of inhibited Heat Transfer Fluids: a Propylene Glycol-based fluid, an Ethylene Glycol-based fluid, an Ethanol-based fluid, and a Methanol-based fluid. Use this convenient reference chart to determine which type of Heat Transfer Fluid is most appropriate for your needs. Note: Due to product evaporation, our Ethanol and Methanol-based fluids are most commonly used in closed-loop geothermal systems. View our Heat Transfer Fluids here.
