Bolztherm AW-66

BOLZTHERM® AW-66 is suitable for use in the liquid phase in closed, non-pressurized heat transfer systems with forced circulation within a temperature range of -3 °C to 355°C, provided that the maximum film temperature of 380 °C is not exceeded. The optimal operating range is between 80 °C and 340 °C. For applications outside the optimal operating range, we request consultation.
