WORKING FLUID FOR ELECTRODE BOILERS Russian patent published in 2003 - IPC

FIELD: closed cycle heating systems. SUBSTANCE: invention represents a working fluid for the electrode boilers used as a heating agent in the closed cycle heating systems. Working fluid contains ethylene glycol or diethylene glycol or propylene glycol or their blend - 30-55 mass %, trinitrophosphate - 0.04-0.10, an ammonium pyromolybdate - 0.03-0.09 and water - the rest. EFFECT: production of the working fluid, that is low foamy with optimal resistivity and corrosion inert to the materials, of which the electrode boilers of the closed cycle heating systems are made. 1 tbl
