Thermogard HT is an environmentally friendly anticorrosive concentrate for heating and cooling systems. It is used if metallic materials are to be protected from corrosion and frost protection is not necessary.
It is free of nitrites, phosphates, amines, silicates, borates and heavy metals.
Thermogard HT is biodegradable and environmentally friendly.
The heat transferability and the viscosity of the water are not influenced by Thermogard HT.
Typical area of application
Thermogard HT is e.g. used for heating systems which are subject to oxygenation despite their closed design (e.g. due to permeable plastics or sealing materials).

Thermogard HT contains a complex combination of corrosion inhibitors which optimally protect metals from corrosion. This corrosive protection can be used for all important metals which are generally used for the construction of heating and cooling systems and industrial plants. Installations made of copper, brass, solder, grey iron, aluminium, steel and iron are optimally protected from corrosion, even if they are used in multi-metal installations. Plastics and sealing materials are resistant to Thermogard HT.

Thermogard HT is delivered in liquid form and can therefore be easily dissolved in water. The applied concentration is 4% (4% Thermogard HT + 96% water).
The water which is used for the production of the solution should have a maximum hardness of 25 °dH and a chloride content of 100 mg/l maximum. Generally, tap water fulfils these requirements. Galvanised components are to be avoided, especially at higher operating temperatures. When installing the plant, it is to be ensured that the future operation is not interrupted by circulatory disturbances caused by air cushions or debris. The plants that are operated with Thermogard HT are to be installed as closed systems and are to be filled completely and vented directly after the pressure test is carried out. Gas and air cushions are to be removed immediately. Breathers are to be applied in such a way that they constantly keep the system free from air and oxygen and no air can be sucked in in case of low pressure. If an existing plant is to be filled, the corrosion condition should be checked first. Before a system that is damaged by corrosion is filled, it is to be reconstructed completely.
Thermogard HT is only used in systems which do not require any frost protection. For areas liable to frost, Glysofor is used.
