Glysofor Solar HT

Description

Glysofor Solar HT is an environmentally friendly solar fluid for systems which could be subjected to high thermal loads.

In special longterm/high-temperature tests, Glysofor Solar HT has shown itself to have comparable resistance to the consequences of overheating (up to 230°C for short periods).

Despite the glycol that it contains being susceptible to decomposition by heating (which cannot generally be prevented), the corrosion inhibitors have demonstrated very good performance. This considerably reduces the risk of the system being damaged by corrosion caused by overheating.

Further information

Glysofor Solar HT is based on propylene glycol, corrosion inhibitors (OAT), and stabilisers, is formulated as a ready-to-use product. It is used both in vacuum tube and flat plate collector solar systems. It meets the requirements of DIN 4757 Part 3 and DIN EN 12975 for solar thermal systems based on its physiological and environmental safety. Glysofor Solar HT is used as an antifreeze, corrosion protection agent as well as the heat transfer medium. Glysofor Solar HT optimally prevents frost damage, corrosion, deposits, sludge accumulation, and biofilms. The freezing point of Glysofor Solar HT is significantly lower than water, allowing solar systems to be safely operated even in sub-zero temperatures. Glysofor Solar HT avoids bursts caused by frost, which also result in damage to the system. A complex combination of corrosion protection additives optimally protects metals from corrosive attack. This corrosion protection is effective on all important metals that are generally used in solar installations. Installations made of copper, brass, solder, grey cast iron, aluminium, steel, and iron are provided with corrosion protection, even if they are implemented as multi-metal installations.

Glysofor Solar HT is completely free of nitrite, amine, phosphate, silicate, and borate. It is biodegradable and environmentally friendly. Glysofor Solar HT exhibits longterm resistance to the formation of biofilms, rot, and microbiological decomposition, which avoids deposition and sludge accumulation. Glysofor Solar HT does not separate during extended system downtimes. This guarantees year-round, longterm, and low-maintenance operation of the system. In its delivered state, Glysofor Solar HT is frost resistant to -28°C.

Miscellaneous

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

In order for the corrosion inhibitors in it to become fully effective, Glysofor Solar HT must be used undiluted.

As an alternative to the ready-to-use product, Glysofor Solar is available as a concentrate. Our products Glysofor N and Glysofor L are available for other application areas.
