Bolztherm AW-58

BOLZTHERM® AW-58 is a synthetic heat transfer fluid specially designed for heating/cooling applications. Thanks to its particularly low viscosity, the heat transfer fluid remains pumpable even at -30 °C. Furthermore, BOLZTHERM® AW-58 can be used in pressurized systems within a temperature range of 278 °C to 360 °C, ensuring the maximum film temperature of 380 °C is not exceeded. The optimal operating range is between 10 °C and 278 °C. For applications outside this optimal range, please contact us for consultation.
