Glysofor EVO N

Description

Glysofor EVO N is an environmentally-friendly antifreeze concentrate and heat transfer medium based on monoethylene glycol in combination with biodegradable corrosion inhibitors.

Glysofor EVO N is used in heating and cooling systems, heat pumps, or other water circuits which are susceptible to frost, and combines the advantages of a MEG-based antifreeze with the optimised biodegradability of the additives it contains.

Free of nitrite, borate, phosphate, triazole, and silicate.

It was specially developed for application areas which have particular environmental requirements, especially in respect of biodegradability, while also focusing on physical characteristics such as heat conductivity and viscosity.

Glysofor EVO N is formulated such that, in the event of unintentional release (e.g. by a leak), the microbial breakdown of the ingredients is not expected to be hindered. Specifically, the good rates at which the ingredients biodegrade into the pure substance is not negatively impacted by the combination of substances in the recipe. Extended half-life periods or an accumulation of persistent intermediate degradation products are also not anticipated during the biodegradation of Glysofor EVO N.

The corrosion inhibition of Glysofor EVO N is completely free of nitrite, nitrate, borate, phosphate, triazole, and silicate. Glysofor EVO N is used simultaneously as an antifreeze, corrosion protection agent as well as the heat transfer medium. Glysofor EVO N ideally prevents frost damage, corrosion, deposits, sludge accumulation, and biofilms. Glysofor EVO N 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 N/water mixtures do not separate, which ensures continuous frost resistance. This guarantees year-round, longterm, and low-maintenance operation of the system.

Heat transfer medium

In heating systems, heat pump systems, heat recovery plants, industrial plants, or water circuits Glysofor EVO N is used as a heat transfer fluid. It guarantees optimum heat transmission from a heat generator to a heat consumer within a water circuit.

Cooling brine / Cooling medium

In industrial cooling systems, Glysofor EVO N is used as a cooling brine. Glysofor EVO 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 EVO N to lower the freezing point, refrigeration and deep freeze systems can be safely operated at sub-zero temperatures at low as -30°C.

Antifreeze

Using glycol, in this case monoethylene glycol, Glysofor EVO N significantly lowers the freezing point of water. In this way, Glysofor EVO N ensures that the aqueous solutions remain in workable liquid form, even in sub-zero temperatures. With Glysofor EVO N, heating, cooling, and water circuits can be temporarily switched off, even during frost conditions, while however remaining ready for operation at any time. Glysofor EVO N reliably avoids bursts caused by frost, which also result in damage to the system.

Corrosion protection

Glysofor EVO N contains a combination of corrosion inhibitors, which provide optimal corrosion protection for metals. All of the corrosion inhibitors used are classed in the lowest water pollution class 1 and have optimum biodegradability. The use of nitrate, nitrite, phosphate, borate, silicate, and triazole was consciously dispensed with in the formulation of Glysofor EVO N.

Other information

Pure water/glycol mixtures have very clearly pronounced corrosive properties. You should therefore never use pure water/glycol mixtures with no inhibitors. For the corrosion inhibitors it contains to be fully effective, Glysofor EVO N must be used in a concentration of at least 25% vol.; this gives frost resistance down to – 12°C.
