heat transfer fluids
Bolztherm SW-500
BOLZTHERM® SW-500 is suitable for use in open heat transfer systems in a temperature range of 0 °C to 250 °C. The maximum film temperature of 310 °C must not be exceeded. The optimal operating range is between 20 °C and 200 °C. For applications outside this range, we recommend prior technical consultation.
