Glicol For Solar Panels

Antifreeze fluids degrade over time and normally should be changed every 3 5 years.

Glicol for solar panels.

Prosol l ht is a clear yellow colored practically odorless liquid based on virgin not recycled propylene glycol water and specially designed industrial package of liquid inhibitors it has been designed specifically for use as a heat transfer fluid in solar thermal systems operating under elevated thermal conditions vacuum tube collectors. When commissioning a pressurized glycol solar hot water system it is essential that all the air in the solar loop is removed. Hydronic heating systems must be filled with water to provide the heat transfer fluid htf that makes them work. The renewable green alternative to ethylene or propylene glycol has a slower thermal degradation rate than both ethylene glycol and propylene glycol and outperforms propylene glycol s viscosity at lower temperatures.

During static conditions the solar collectors should be completely empty so that the thermal fluid is not exposed to extreme temperatures. Never use more than 60 glycol in the mix. 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. It has a long track record over many decades in this application and is widely available from a number of sources.

Propylene glycol pg has become the most common heat transfer fluid used in closed loop solar heating systems that contain antifreeze. When you re choosing a glycol bear in mind the following. Air in the loop can cause pump. This is obviously catastrophic for any solar thermal installation and must be avoided.

In the case of the closed loop solar heating system the htf is typically a mixture of water and propylene glycol. For solar thermal applications mixtures based on propylene glycol or the green glycol are recommended.

Never use less than 20 glycol in the mix. Always mix in as little glycol as possible to keep optimum efficiency but never risk burst pipes.
