Heat transfer fluids

Bolztherm AW-50


Bolztherm AW-50

BOLZTHERM® AW-50 is ideally suited for heating and cooling applications due to its unique composition. It is approved for use in closed, non-pressurized heat transfer systems with forced circulation within a temperature range of -56 °C to 260 °C, ensuring that the maximum film temperature of 285 °C is not exceeded. The optimal operating range is between 30 °C and 250 °C. For applications outside this range, please contact us for further consultation.
