Climalife: Heat Transfer Fluids – More than just Glycol

H TFs are used in refrigeration, air conditioning, central heating, heat pump, solar thermal and underfloor heating applications. Although they are often one of the least expensive components of a system, a heat transfer fluid is critical to the way it functions and how effectively it transfers energy from one location to another and provides protection from freezing and corrosion. When poor quality HTFs age, they can degrade meaning they can become less effective at freeze protection, the inhibitor package may become compromised leading to common problems such as corrosion, the formation of sludge and a change in viscosity, each of which can reduce the efficiency of systems.
