Glycol Solar Panels

Fernox protector solar s1 is supplied as a ready to use premix in 10 and 20 litre sizes.

Glycol solar panels.

Typically any time a system has a glycol bulk temperature in the range of 250 f 121 c fluid degradation increases. Glycol is now pumped out of the bucket filling the solar collectors from the bottom to the top. Fernox solar s1 is classified as non hazardous and non irritant but as with all chemicals keep out of the reach of children. The industry standard for solar fluid is a mix of propylene glycol and water.

At first air returns into the bucket and then glycol mixture with air and foam which can be very hot. Air in the loop can cause pump. Propylene glycol pg has become the most common heat transfer fluid used in closed loop solar heating systems that contain antifreeze. Antifreeze fluids degrade over time and normally should be changed every 3 5 years.

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.

However you should always mix as much water as possible with your choice of glycol product as simple water is the ideal solar fluid. However no warranty is expressed or implied regarding the accuracy of these data or the results to be obtained from the use thereof.

In most solar heating applications the solar collectors are exposed to periods of freezing as such the solar heating heating fluid needs to be able to with stand freezing. The formulation should not be diluted prior to use. Do not take internally. Air in the collectors and the pipe is pushed out the purge hose back into the top of the bucket by the charge pump.

It has a long track record over many decades in this application and is widely available from a number of sources. In all three scenarios if a glycol fluid is used the residual glycol remaining in the panels becomes acidic and can cause corrosion issues. When commissioning a pressurized glycol solar hot water system it is essential that all the air in the solar loop is removed. The information contained herein is based on data considered accurate.

It s non toxic biodegradable and relatively stable. By code any solar application involving potable drinking water must use a non toxic blend of solar glycol known as propylene. This is done through the use of mixing water with specially formulated solar glycol to avoid freezing and large scale damages.
