Application
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-PGA with water enables lower working temperatures, increases the boiling point and simultaneously prevents corrosive attacks on metallic systems.
The proven product FRAGOLTHERM® W-PGA 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-PGA can be used for the following:
- Heating
- Process temperature control
- Underfloor heating
- Air-conditioning systems
- Cooling coil defrosting
- Heat recovery
- Solar plants
- Ice production
FRAGOLTHERM® W-PGA is almost entirely odourless.. 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-PGA is free of amines and nitrites, thus preventing the formation of nitrosamines.
FRAGOLTHERM® W-PGA is based on propylene glycol and has even better toxicity values than FRAGOLTHERM® W-PGA. The FDA (Food and Drug Administration) has recognised propylene glycol universally as a food additive in part 182 of the FDA regulations for food additives.
Constant temperatures of more than 170 °C lead to the premature ageing of FRAGOLTHERM® W-PGA. It is therefore recommended to make the expansion tanks as large as possible in the case of solar plants with standstill temperature of more than 170 °C so that heat transfer fluid can flow out of the collectors and be captured by the expansion tanks when the maximum standstill temperature is reached.
