Heat transfer fluid from -50°C to 170°C

FRAGOLTHERM® W-EGA is a water-miscible heat transfer fluid based on ethylene glycol that is used in a range of -50 °C to 170 °C.

Application Area


Water, the best and most economical heat transfer medium, freezes at 0 °C and has a corrosive effect on many metals and alloys. Mixing FRAGOLTHERM® W-EGA with water enables lower working temperatures, increases the boiling point and simultaneously prevents corrosive attacks on metallic systems. The proven product FRAGOLTHERM® W-EGA is an optimum additive-enhanced liquid that can be mixed with normal tap water for a wide range of applications. Sufficient corrosion protection exists from a glycol proportion of 30 %.

FRAGOLTHERM® W-EGA is based on ethylene glycol and can be used for the following:

  • Heating
  • Process temperature control
  • Underfloor heating
  • Air-conditioning systems
  • Cooling coil defrosting
  • Heat recovery

FRAGOLTHERM® W-EGA is based on ethylene glycol. It is almost entirely odourless and biodegradable. It is compatible with the common elastomers EPDM, PE, PP and SBR. Separate data sheets are available for the technical and physical properties. FRAGOLTHERM® W-EGA is free of amines and nitrites, thus preventing the formation of nitrosamines.

Constant temperatures of more than 170 °C lead to the premature ageing of FRAGOLTHERM® W-EGA.
