Glysofor N

Description

Glysofor N is an environmentally-friendly antifreeze concentrate based on monoethylene glycol, corrosion inhibitors, and stabilisers.

It may be used universally as an antifreeze, corrosion protection agent, and heat transfer medium or cooling transfer medium (cooling brine) in heating and cooling systems.

Glysofor N does not attack the known sealant materials and is also very well suited to use in combined systems (multi-metal installations). It can be mixed with water in any ratio and offers reliable frost protection down to -50 degrees Celsius, depending on requirements and dilution. Glysofor N is free of nitrites, phosphates and amines.

Typical areas of application

Heating and cooling systems, heat recovery plants, heat pumps and other liquid-carrying systems.

Further information

Glysofor N optimally prevents frost damage, corrosion, deposits, sludge accumulation, and bio-films. Glysofor N is completely free of nitrites, amines, phosphates, silicates, and borates. It is biodegradable and environmentally friendly. Both as a concentrate and diluted, Glysofor N is classed in the lowest water pollution class, WGK 1. Glysofor N exhibits long-term resistance to the formation of bio-films, rot, and resistance to microbiological decomposition, which avoids deposition and sludge accumulation. Homogeneous Glysofor N/water mixtures do not separate, which ensures continuous frost resistance. This guarantees year-round, long-term, low-maintenance operation of systems filled with Glysofor N.

Heat transfer medium

In heat pump systems, heat recovery plants, industrial plants, downhole heat exchangers, or water circuits, Glysofor N is used as a heat carrier fluid. This guarantees the heat transfer of previously generated or excess heat to a heat consumer that makes this heat useful. The high boiling point of Glysofor N (approx. 200 °C) prevents evaporation losses. In case geo-thermal heat is used, Glysofor N 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 N is able to function simultaneously as a cooling medium, which guarantees optimal heat removal at the same time as cooling.

Cooling brine / Cooling medium

In industrial cooling systems, Glysofor N is used as a cooling brine. Glysofor N is used to transfer cold from a central refrigeration system to different cooling consumers. Typical application areas are air-conditioning systems or cooling equipment in industrial and production facilities. Thanks to the excellent ability of Glysofor N 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 (monoethylene glycol), Glysofor N significantly lowers the freezing point of water and prevents fluid from freezing, e.g. in heating systems or cooling systems. With Glysofor N, 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 N 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. We recommend Glysofor L, which is based on propylene glycol, for food-related applications, cooling or heating of food as well as for pharmaceutical and cosmetic applications.
