Bolztherm Food Grade 700
BOLZTHERM® FOOD GRADE 700 is excellently suited for high-temperature applications due to its unique composition and is approved for use in closed, non-pressurized heat transfer systems with forced circulation in the temperature range of -15 °C to 327 °C, provided that the maximum film temperature of 347 °C is not exceeded. The optimal operating range is between 110 °C and 300 °C. For applications outside this optimal range, please contact us for consultation.
