SONITHERM E 22 is a 100% synthetic heat transfer fluid usable in the liquid phase between -10°C and +315°C, and with a much better thermal stability than that of mineral oil-based fluids.
Although a low-viscosity thermal fluid (22 mm2/s at 40°C), SONITHERM E 22 possesses a high flash point and fire point, enabling the system to work under better safety conditions than with a mineral-based fluid.
