The other factor specific to solar glycol is is ability to completely vaporize or steam when stagnation temperatures are present.
Glicol for solar panels.
Using an antifreeze solution solar water heating systems that use an antifreeze solution propylene glycol or ethylene glycol as a heat transfer fluid have effective freeze protection as long as the proper antifreeze concentration is maintained.
The following criteria could be used to choose the right type of glycol for a solar thermal application.
Dynalene solar glycol xt msds page 3 of 5 keep container tightly closed.
Most glycol will break down and become acid needing immediate replacement if those temperatures are reached.
Store in a cool dry place respiratory protection.
Solar glycol such as prosoltm l ht is rated to 425 f with short periods of up to 475f.
Consult a solar heating professional or the local authority having jurisdiction to determine the requirements for heat transfer fluid in solar water heating systems in your area.
Keep away from heat and open flames.
A closed loop solar glycol collector system has been designed a piping.
Installing the right components.
The industry standard for solar fluid is a mix of propylene glycol and water.
Sentinel r100 solar thermal fluid is glycol based and designed for use in solar heating equipment operating up to 200 c.
Antifreeze fluids degrade over time and normally should be changed every 3 5 years.
The following are some of the most commonly used heat transfer fluids and their properties.
High thermally stability at temperatures up to 350 f 177 c.
Before the filling begins.
High reserve alkalinity or good ph buffering.
Where there is a potential for airborne exposure wear appropriate niosh approv ed respiratory protection.

However you should always mix as much water as possible with your choice of glycol product as simple water is the ideal solar fluid.
The plumbing is complete and all the components are in place according to.
It has a long track record over many decades in this application and is widely available from a number of sources.
It s non toxic biodegradable and relatively stable.
