FRAGOLTHERM® 680 can be used in its liquid phase up to 309 °C. In pressurized systems, the maximum temperature of the flow can be increased to 360 °C.
-
FRAGOLTHERM® DPO is a synthetic heat transfer fluid that can be used in a temperature range between 12 °C and 400 °C. The film temperature at the heating element must not exceed 430 °C.
-
FRAGOLTHERM® DPO is a high-temperature-stable heat transfer fluid for use in temperature-critical systems. Typical applications include, for example, the production of synthetic fibers and fine chemicals, concentrated solar power (CSP), and plastics recycling.
-
Therminol® 72 is a high-temperature liquid-phase thermal oil with excellent thermal stability. Therminol® 72 is designed for temperatures up to 380°C in the liquid phase of a thermal system.
-
Therminol® VP-1 is a thermal oil designed for very high temperatures and offers excellent thermal stability. Therminol® VP-1 is designed for temperatures up to 400 °C and can be used in both the gas and liquid phases of a thermal system. The system requires a static pressure of approximately 10 bar to operate in the liquid phase at high temperatures.
