Glycol Solar Panels

All glycol products used in solar fluid mixes come with a dilution chart an example of which is shown below.

Glycol solar panels.

Do not take internally. The formulation should not be diluted prior to use. This glycol is completely non toxic safe for all types of solar heating applications and is made from sustainable bio based raw materials. 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. The spp corn glycol is specifically designed for chillers radiant heating air to water hydronic heat pump and solar thermal applications such as solar hot water or solar space heating. Propylene glycol pg has become the most common heat transfer fluid used in closed loop solar heating systems that contain antifreeze. 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.

At first air returns into the bucket and then glycol mixture with air and foam which can be very hot. Antifreeze fluids degrade over time and normally should be changed every 3 5 years. 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 industry standard for solar fluid is a mix of propylene glycol and water.

Fernox protector solar s1 is supplied as a ready to use premix in 10 and 20 litre sizes. Typically any time a system has a glycol bulk temperature in the range of 250 f 121 c fluid degradation increases. The information contained herein is based on data considered accurate. Air in the collectors and the pipe is pushed out the purge hose back into the top of the bucket by the charge pump.

This is done through the use of mixing water with specially formulated solar glycol to avoid freezing and large scale damages. When commissioning a pressurized glycol solar hot water system it is essential that all the air in the solar loop is removed.

It has a long track record over many decades in this application and is widely available from a number of sources. However no warranty is expressed or implied regarding the accuracy of these data or the results to be obtained from the use thereof. Fernox solar s1 is classified as non hazardous and non irritant but as with all chemicals keep out of the reach of children.
