ALIGEL, ALIGEL HC20BIO and ALIGEL HC30BIO are antifreeze agents based on monopropylene glycol, and due to their non-toxic characteristics and high resistance to temperature changes, they can also be used in vacuum panels.
There are certainly algae formed due to the air permeability of the system, also favored by the water temperature on 35 to 40 °C. In such cases, it is necessary to clean the system with the broad-spectrum biocide THERMAKIL, circulating with special DISIFLUX pump with high head. It normally takes only 30 to 60 minutes to break down even the most stubborn forms of aerobic and anaerobic bacteria.
Yes, SOLAR CLEAN in fact is a quick and effective cleaner specifically designed to remove with extreme speed sludge and sludge generated by solar fluids degraded by over-exploitation and high temperature changes that could create clogging in collector pipes.
In case of limescale/fouling phenomena, I need to add food-pure polyphosphates to the drinking water, which prevent the formation of limescale and consequent corrosive effects due to carbon dioxide formation.
Yes, after this period has elapsed, the active ingredients have been leached out so, in order to have full protection, you need to change the bag every six months.
