FRAGOLTHERM® DPO
FRAGOLTHERM® DPO is a high-temperature stable heat transfer fluid for use in temperature-critical systems. Typical application areas include, for example, the production of synthetic fibers and fine chemicals, concentrated solar energy (CSP), and plastics recycling.
FRAGOLTHERM® DPO is a high-temperature stable heat transfer fluid for use in temperature-critical systems. Typical application areas include, for example, the production of synthetic fibers and fine chemicals, concentrated solar energy (CSP), and plastics recycling.
FRAGOLTHERM® DPO can be used in both the vapor and liquid phases up to 400 °C. In the liquid phase, the product can be used pressureless within a temperature range between 12 °C and 257 °C and under pressure up to 400 °C. The film temperature during heating must not exceed 430 °C.
FRAGOLTHERM® DPO crystallizes below 12 °C, but without volume expansion. On pipelines and system components where the fluid does not flow constantly or where the temperature is lower than 12 °C, a heat supply must be provided.
Even when used in non-pressurized series in the liquid phase, a nitrogen blanket in the expansion vessel is recommended to prevent premature aging.
