THERMISOL QH 40 is a thermally stable, high performance Quenching Oil with a high flashpoint and very low viscosity and it offers extremely rapid cooling. The product gives excellent results even with components of widely varying cross-sections. The high cooling speed of the product minimizes local stresses in treated components. THERMISOL QH 40 can be used for the heat treatment of alloyed and unalloyed constructional and tool steels.
Benefits of using THERMISOL QH 40
Free of asphalt and completely neutral
Surfaces remain free of any desposits after quenching.
No decompositions caused by treated parts coming directly from salt the quenching processes
Not hazardous according to the law on hazardous substances
Free of chlorine and PCB, thus ensuring simple and cheap disposal

Application: The special thermo-chemically stable and practically unlimited service life of THERMISOL QH 40 makes it well suited for use in multipurpose furnaces, gas carbonization lines and vertical retort facilities.
THERMISOL QH 40 is normally used at temperatures between 50 °C and 110 °C and up to 150 °C in closed facilities. For continuous operation at higher temperatures we recommend our higher performance products, THERMISOL QH 80 and THERMISOL QH 120.
