Bolztherm AW-68

BOLZTHERM® AW-68 is a synthetic heat transfer fluid specially developed for high-temperature applications. BOLZTHERM® AW-68 can be used in pressurised systems within a temperature range of 308 °C to 360 °C, provided that the maximum film temperature of 390 °C is not exceeded. The optimal operating range is between 50 °C and 340 °C. For applications outside the optimal operating range, please contact us for consultation.
