Polartherm P is based on non-toxic propylene glycol, also known as propane-1,2-diol (MPG), and serves as a heat transfer fluid that provides protection against freezing and boiling. Its organic corrosion inhibitors ensure effective protection of metal surfaces against corrosion. When mixed with water in the appropriate ratio (e.g., products Polartherm P50, P40, and P30, where the number indicates the concentration in volume percent), it is suitable for use in heating, ventilation, and air conditioning systems (HVAC), secondary cooling systems, ground-source heat pumps, solar panels, and other heat exchange applications.
Many industrial applications require a fluid that can transfer heat or cold. Examples include solar panels and heat pumps, industrial cooling and heating systems, artificial ski slopes, and ice rinks, among others. Such a heat transfer fluid is often referred to as a secondary heat transfer fluid. An ideal secondary heat transfer fluid should provide good thermal conductivity, high specific heat, and low viscosity. It is also important that the fluid is non-flammable and compatible with the materials used in the system.
Mixing different products should be avoided, as this can cause chemical incompatibility and reactions whose effects are difficult to monitor and control later. To ensure the best corrosion protection, sediment-free performance, and long service life, it is recommended to use only a Polartherm P and water mixture. Soft water is preferred for dilution. Laboratory tests have shown that satisfactory corrosion results can also be achieved with water having a hardness of up to 20°dH and containing up to 100 ppm of chlorides and 100 ppm of sulfates.
