The corrosion inhibition of Glysofor EVO L is completely free of nitrite, borate, phosphate, triazole, and silicate. The corrosion inhibition of Glysofor EVO L is completely free of nitrite, borate, phosphate, triazole, and silicate. The main ingredient propylene glycol is preferred in the food and luxury foodstuffs sector due to its physiologically and environmentally harmless properties. Glysofor EVO L is used as an antifreeze, corrosion protection agent as well as the heat transfer medium. Glysofor EVO L ideally prevents frost damage, corrosion, deposits, sludge accumulation, and biofilms. Glysofor EVO L is biodegradable, environmentally friendly and, in water circuits, exhibits longterm resistance to the formation of biofilms, rot, and microbiological decomposition, which avoids deposition and sludge accumulation. Homogeneous Glysofor EVO L/water mixtures do not separate, which ensures continuous frost resistance. This guarantees year-round, longterm, and low-maintenance operation of the system.
