Abstract. To find out the reason for the high oxygen content in the water from the tank of the hot water supply accumulator No. 2 of JSC GSR CHP, the physico–chemical parameters of the sealing liquid AG–4I (TU 2513-018-72205759-2014) produced by Standard LLC were determined, as well as the content of metals and other elements in it, the structural and group composition of the base base of the sealing liquid, water washability from its composition of aromatic hydrocarbons.
It is established that the sealing liquid AG-4I (TU 2513-018-72205759-2014) produced by Standard LLC cannot be used in the hot water tank of JSC GSR CHP, because it does not comply with the regulatory and technical documentation on its composition and operational indicators and its use harms the health of the consumer.
