Retail shelves, etc, where there is a possibility of contact (In emergency situations, leakages) with drinking water and foodstuffs. * Required certificates of the State Sanitary and Epidemiological Service of the Russian Federation, of course, the Russian realities suggest the feasibility of using antifreeze in hydronic systems. At the same time we must note their characteristics, which do not allow the use of antifreeze everywhere. Physical properties include anti-freeze certain parameters of the heating system, a standard designed for the water paths, they can not fill. Type of fluid affects the capacity of the boiler, radiators (radiators, convectors), the parameters of the pump and the possibility of using different materials of the heating system. Antifreeze should not be used in galvanized pipe, cast iron boilers, boilers in a certain type of filling material. Many manufacturers heating equipment in the passport of their products directly indicate the inability to use antifreeze.
Most fluids can work with all types of boilers – gas, diesel, electrical, but not suitable for electrolysis of boilers (such as "Gala"), in which heating takes place by passing electric current through the coolant. For this case, issued special stamps. Adverse effects on antifreeze may have too high a temperature that occurs when an abnormal operation of the heating system. In case of overheating of coolant over +107 C increases the rate of thermal decomposition of ethylene glycol and anticorrosion additives. To avoid this effect, it is necessary to ensure proper circulation of coolant in the heating system. In applying the antifreeze should take into account that: antifreeze heat for about 10-15% lower than that of water (it is worse and worse heat accumulates gives it), therefore, the radiators have to choose a more powerful anti-freeze strength higher than that of water, so you need to choose a more powerful circulation pumps, antifreeze is more fluid than water, hence the increased demands on the detachable connections of the heating system. More to the analysis of the current situation and outlook for the Russian market cooling liquids can be found in the records of the Academy of marketing research Conjuncture industrial markets, "market of automobile fluids (antifreeze, antifreeze) in Russia."
