Specialists in the formulation of HTFs over the past 30 years, Climalife have devoted two years of research to responding to 3 key needs:
- investigating efficient and sustainable heat transfer
- reducing premature ageing at high temperatures or during periods of overheating
- preserving the installation's ROI at all costs
Let's look in more detail at the various applications and the solutions which best meet their needs:
1. For installations where constraints are mastered: where the use is continuous throughout the year, correctly sized or presenting large discharge capacity (eg swimming pool):
Solufluid® Solar - the market's classic HTF:
2. For installations with strong constraints: vacuum tubes, oversized, subject to periods of non-use (schools in summer holiday etc), with repeated overheating periods. In this instance the ageing of a MPG-based HTF will be quick.
For new installations: prevention is better
Greenway® Solar : the bio-chemical alternative to petrochemical glycols:
For existing installations: cure and prevent
SolRnett : the new internal cleaner which can increase a system's lifespan.
- Restores circulation
- Avoids replacement of collectors
- Effective at room temperature, or heated
Climalife recommends the use of a specialist heat transfer fluid such as Greenway® Solar !
Indeed, a major problem but one which not enough is known about: premature ageing.
More and more reports show systems in default because of the premature ageing of MPG-based heat transfer fluids. It results in a darkening in colour, an increase in acidity, a decrease in thermal exchange efficiency, an increase in viscosity, and even ultimately a total caramelisation, avoiding any circulation at all, which in turn leads to the need to replace the solar collectors. The system's ROI will suffer as a result. This outcome can be prevented however, with the use of a specialist cleaning product such as SolRnett.
Very often when this situation occurs, the system is returned to service and the MPG-based heat transfer fluid is replaced by another MPG-based heat transfer fluid which will result is exactly the same problems!
