Thermal H300

Thermal H300 is a transparent, high-performance hydrocarbon-based heat transfer fluid that is odorless and has very low toxicity.

Thermal H300 has a high thermal stability and therefore has a very long life-time, especially in the upper temperature limit range. The low vapor pressure allows almost pressureless operation in heat transfer systems. The bath fluid has the advantage of being odorless. In the case of thermal decomposition, no toxic products such as benzene or phenol are produced.

Despite the low oxidation tendency, in order to prevent premature aging, JULABO recommends covering the expansion tank with nitrogen when used in the high temperature range.

Due to its properties, Thermal H300 doesn't need to be declared as a hazardous substance.
