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.

Fernox protector solar s1 is supplied as a ready to use premix in 10 and 20 litre sizes. Fernox solar s1 is classified as non hazardous and non irritant but as with all chemicals keep out of the reach of children.

This glycol is completely non toxic safe for all types of solar heating applications and is made from sustainable bio based raw materials.

When commissioning a pressurized glycol solar hot water system it is essential that all the air in the solar loop is removed. Do not take internally. The information contained herein is based on data considered accurate. However you should always mix as much water as possible with your choice of glycol product as simple water is the ideal solar fluid.

In all three scenarios if a glycol fluid is used the residual glycol remaining in the panels becomes acidic and can cause corrosion issues. The industry standard for solar fluid is a mix of propylene glycol and water. Glycol is now pumped out of the bucket filling the solar collectors from the bottom to the top. Antifreeze fluids degrade over time and normally should be changed every 3 5 years.

It s non toxic biodegradable and relatively stable. Air in the loop can cause pump. 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 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.

However no warranty is expressed or implied regarding the accuracy of these data or the results to be obtained from the use thereof. Typically any time a system has a glycol bulk temperature in the range of 250 f 121 c fluid degradation increases. It has a long track record over many decades in this application and is widely available from a number of sources. At first air returns into the bucket and then glycol mixture with air and foam which can be very hot.

Propylene glycol pg has become the most common heat transfer fluid used in closed loop solar heating systems that contain antifreeze. This is done through the use of mixing water with specially formulated solar glycol to avoid freezing and large scale damages. The formulation should not be diluted prior to use.
