The content of corrosion inhibitors in FRAGOLTHERM® W-VR protects all metal materials conventionally used in solar technology and mixing installations on a long-term and reliable basis against corrosion, ageing and incrustation. FRAGOLTHERM® W-VR keeps the heat transfer surfaces clean and in this way guarantees a consistently high degree of efficiency of the plant to be protected.
If the following conditions are observed, FRAGOLTHERM® W-VR can be used in solar plants that reach standstill temperatures of up to 320 °C:
Temperatures above 200 °C lead to a slow thermal decomposition of the 1.2 propylene glycol that can be detected by dark colouration of the heat transfer fluid. This can severely reduce the service life of the medium.
