Heat transfer fluids

Bolztherm CW-8

BOLZTHERM® CW-8 is excellently suited for heating/cooling applications due to its unique composition and is approved for use in closed, non-pressurized heat transfer systems with forced circulation in a temperature range of -20 °C to 275 °C, provided that the maximum film temperature of 285 °C is not exceeded. The optimal operating range is between 55 °C and 255 °C. For applications outside the optimal operating range, we request consultation.
