Glysofor L

Description

Glysofor L is a universally useable heat transfer, refrigeration and anti freeze agent for industrial systems and technical, liquid carrying systems.

Through its positive physiological and ecological rating, Glysofor L is especially suited to systems in operation in the areas of food processing, pharmaceuticals production, medicine and other hygiene-related areas.

Glysofor L is neither a hazardous substance nor hazardous material. Glysofor L is equipped with a modern inhibitor system which protects against corrosion and guarantees long term, low maintenance operations.

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.

Heat transfer medium

In heat pump systems, heat recovery plants, industrial plants, downhole heat exchangers, or water circuits, Glysofor L is used as a heat transfer fluid. This guarantees the heat transfer of previously generated or excess heat to a heat consumer that makes this heat useful. In the geothermal area, use of a product which is as physiologically and environmentally safe as possible may be advisable due to the geographical proximity to surface water, drinking water wells, or areas of natural protection. In this case, Glysofor L water-mixtures often meet such sensitive requirements. In case geo-thermal heat is used, Glysofor L transports the heat absorbed in the downhole heat exchangers at the earth's surface and releases them to a heating system in connection with a heating pump. Glysofor L is able to function simultaneously as a cooling medium, which guarantees optimal heat removal at the same time as cooling.

Cooling brine / Cooling medium

Glysofor L is used to transfer cold from a central refrigeration system to different cooling consumers. Typical application areas include air-conditioning systems or cooling equipment for food and luxury food production facilities. Glysofor L is supplied as a concentrate and, depending on the frost protection desired, can be mixed with water in any ratio. Thanks to the excellent ability of Glysofor L to lower the freezing point, refrigeration and deep freeze systems can be safely operated at sub-zero temperatures at low as -50 °C.

Antifreeze

Using glycol, in this case monopropylene glycol, Glysofor L significantly lowers the freezing point of water and prevents fluid from freezing, e.g. in heating systems or cooling systems. Glysofor L ensures that the aqueous solutions remain in workable liquid form, even in sub-zero temperatures. With Glysofor L, heating systems can be temporarily switched off, even in frost conditions, while however remaining ready for operation at any time. In temporarily used facilities like sports halls, weekend homes, churches, schools, or events spaces, it can lead to a significant reduction in the used of fuels. Glysofor L reliably avoids frost damage to the system caused by bursting effects.

Corrosion protection

Thanks to a complex combination of corrosion inhibitors, metals are optimally protected against corrosive attacks. This anticorrosive protection can be used for all important metals that are usually used in heating engineering. Installations made of copper, brass, solder, grey iron, aluminium, steel and iron are optimally protected, even if they are used in multi-metal installations.

Other information

Pure water/glycol mixtures have very clearly pronounced corrosive properties. You should therefore never use pure water/glycol mixtures with no inhibitors.
