HEAT CARRIER Russian patent published in 2019 - IPC C09K5/08 

FIELD: heating equipment.

SUBSTANCE: invention relates to an organic coolant that can be used to heat process equipment in wide industries. Heat carrier with Cml. (-)7.5 – (-)9.0 °C includes, in wt. %: diphenyl, 14.50–17.50, diphenyl oxide, 42.50–45.50, and vacuum gas oil, 37.00–43.00. Invention provides a heat carrier with a low melting point of 19.8–21.3 °C as compared with the prior art in this field, it allows to expand temperature range of use of the heat carrier and to reduce energy consumption for fusion and maintenance in working order.

EFFECT: invention allows to expand the temperature range of coolant use and reduce energy consumption for melting and maintenance in working condition.
