Thermal H300 is a transparent, high-performance, hydrocarbon-based heat transfer fluid that has very low toxicity.
Working temperature: +40 °C ... +300 °C
Broad temperature range
Exceptionally high stability
Excellent heat conductivity
Long fluid life
The low vapor pressure allows almost pressureless operation in heat transfer systems. In the case of thermal decomposition, no toxic products such as benzene or phenol are produced. Due to its properties, Thermal H300 doesn't need to be declared as a hazardous substance. 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.
JULABO Thermal bath fluids are carefully selected and long-term tested media with ideal thermodynamic properties for a variety of applications. These bath fluids are ideally suited for temperature applications using JULABO instruments, and ensure safe, reliable operation as well as optimum heat transfer efficiency.
Please note: If the fluid is used below the specified lowest working temperature, this can cause the temperature to fluctuate or the overtemperature alarm to trigger because the fluid on the heater is too hot. Recommendation: Reduce the heater capacity during the heat-up process until the lowest specified working temperature is reached.
Use of silicone tubing: Silicone tubing is suitable only for limited use with hydrocarbon-based fluids since the plasticizers it contains will dissolve, causing the tubing to become brittle. There may therefore be a risk of injury, especially at high temperatures.
