Glysofor L is an environmentally-friendly heat transfer and antifreeze concentrate based on propylene glycol, corrosion inhibitors, and stabilisers. Due to its physiological and ecological harmlessness, Glysofor L is preferred in the food and luxury foodstuffs sector and in pharmaceutical and ecologically sensitive areas of application. Typical areas of application for Glysofor L include dairies, the beverage industry, breweries, fish and meat processing operations, deep-freeze chains, solar systems. Glysofor L serves as an antifreeze, corrosion protection agent, and heat transfer medium or cooling medium (cooling brine) in heating and cooling systems. Glysofor L optimally prevents frost damage, corrosion, deposits, sludge accumulation, and bio-films. Glysofor L is completely free of nitrite, amine, phosphate, silicate, and borate. It is biodegradable and environmentally friendly. Glysofor L exhibits long-term resistance to the formation of bio-films, rot, and resistance to microbiological decomposition, which avoids deposition and sludge accumulation. Homogeneous Glysofor L/water mixtures do not separate, which ensures continuous frost resistance. This guarantees year-round, long-term, low-maintenance operation of systems filled with Glysofor L.
