When using ordinary water as a coolant in heating systems, consumer faces several substantial problems. Water contains various salts and admixtures which cause not only corrosion of the heating element, but even salt deposits formation and biological fouling on heat-exchange surfaces, leading to deterioration of a technical condition and working capacity of all heating system elements. More over, water can be used as a coolant only at external temperatures above zero degrees centigrade.
Considering the aforementioned, our company has developed a low-freezing coolant “BERIL” based on ethylene glycol with antifoaming and corrosion-preventing additives, in accordance with ГОСТ 28084-89 "Low- freezing liquid cooling" (“Low Freezing Coolants”), as well with additives which prevent constructive destruction of heat-exchange devices elements..
Furthermore, keeping up with the times, an ecologically safe coolant “BERIL V.I.P.” have been developed, based on a propylene glycol which is widely used in many consumer products like shampoos, medications, cosmetics, animal feeding products and non-alcoholic drinks. “BERIL V.I.P.” is used in standalone heating systems, climate control systems, refrigerating equipment in food industry and so on.
“BERIL V.I.P.” has lower density in comparison with other coolants; therefore it provides a faster heat transfer even to the most distant heating elements. As a result, the recycling pump is under lower load and serves longer.
The company produces both coolants (“BERIL” and “BERIL V.I.P.”) with crystallization (freezing) temperature of -30 ºC. This value remains unchanged for several years of operation providing that the coolant concentration is the same
From the diagram it can be seen that in between the crystallization starting point and solidification point there is a considerable temperature difference, and within this range both phase states, namely liquid and solid crystals (slush), exist simultaneously, thus there is no “disruption” effect related to the expansion of freezing water.
Due to this effect, heating system cannot be destructed upon defrosting as it could happen in case of water use. Final freezing temperature of the manufactured coolants is a temperature of -45 ºC.
Ministry of Health of the Russian Federation in its conclusion recommends “BERIL V.I.P.” to be used in heating systems and other heating equipment operated at low temperatures. Both coolants are sold in 20 l polyethylene cans. Can price is: for “BERIL” – 20.00 LVL, for “BERIL V.I.P.” – 25.00 LVL
