Bolztherm AW-65

BOLZTHERM® AW-65 is suitable for use in the liquid phase in closed, non-pressurized heat transfer systems with forced circulation in a temperature range of -12 °C to 350 °C, ensuring that the maximum film temperature of 380 °C is not exceeded. The optimal operating range is between 70 °C and 330 °C. For applications outside this optimal range, please contact us for consultation.
