Product description
Propylene-glycol-water mixtures are commonly used as heat transfer fluids. An antifreeze concentration of about 40% glycol in the mixture prevents damage to the system. even at temperatures of -21 °C, the system remains usable. temperatures below this protection point cause the formation of ice pulp, which, however, is unable to destroy pipes and ducts.
Important note on the use of heat transfer fluids:
Use only heat transfer fluids that are suitable for the system in which they are used. All system components in contact with fluids must be glycol-resistant. Concentrations of more than 50% glycol should be avoided to achieve optimum efficiency.
Applications
However, today's high-quality flat collectors and direct-flow vacuum tube collectors can lead to premature degradation of the conventional heat transfer fluid at high stagnation temperatures. To prevent this process, the operating pressure of the system can be limited to 4 bar or a heat transfer fluid resistant to high temperatures can be used.
*Please note that a basic knowledge of electrical engineering is required (for installation) when purchasing some products on our webshop.
