Description :
Greenway® Solar -30°C is a ready-to-use heat transfer fluid based on 1.3-Propanediol (Bio-PDO™) and organic long-duration corrosion inhibitors.
The raw material used, 1.3 Propanediol, comes from renewable plant-based materials.
The formulation of Greenway® Solar is Borax-free in order to comply with the European Directive 2005/58/CE of 15/09/2008.

Greenway® Solar is particularly suitable for sanitary hot water production in thermal solar systems at medium temperatures (panels) and high temperature (vacuum tubes).

The high thermal stability of Greenway® Solar is one of its innovative characteristics for application in thermal solar systems.
It provides protection against periods of stagnation, avoids the "tarring" of systems and gives installations a longer working life.
At over 150 °C for 150 hours, Greenway® Solar degrades three times more slowly than a traditional 50% concentrated solution of Mono Propylene Glycol.

Environmental gain
Greenway® Solar's environmental footprint is reduced by 40% in terms of CO2 emissions and energy use compared with a traditional Mono Propylene Glycol heat transfer fluid (oil industry product).
Environmental impact is also a determining factor in the development of Greenway® Solar -30°C. The analysis of the life cycle, performed by SGS according to the standards ISO 14040 and ISO 14044, shows that Greenway® Solar -30°C has a lower impact than MPG -30°C according to 5 indicators. We observe for example that its impact on damage to the ozone layer is almost nil and that Greenway® Solar has a lesser influence on climate change.

The formulation of Greenway® Solar is Borax-free in order to comply with the European Directive 2005/58/CE of 15/09/2008.
