Bolztherm SWH-430

BOLZTHERM® SWH-430 is suitable for use in the liquid phase in heat transfer systems in a temperature range of -60 °C to 430 °C. The maximum film temperature of 430 °C must not be exceeded. The optimal operating range is between 30 °C and 425 °C. For applications outside this range, we recommend prior technical consultation.
