Art.-No. 32164
Description
STRUB GEO-OAT N is a nitrite-, amine-, phosphate- and silicate-free mixture of corrosion inhibitors and monoethyl-englycol, according to the latest Organic Acid Technology (OAT).
Complies with all international specifications for antifreeze systems in terms of material compatibility, temperatures, long-term use, corrosion, etc.
Features
STRUB GEO-OAT N is a clear, yellow colored, slightly smelling liquid based on mono-ethylene glycol. The product is miscible with water in any ratio and, depending on the concentration, provides frost protection down to approx. - 50°C. Mixtures of STRUB GEO-OAT N and water do not segregate. The corrosion protection inhibitors of STRUB GEO-OAT N protect all metal materials commonly used in heat pump technology against corrosion, aging and incrustation for a long time and reliably, even in mixed installations.
STRUB GEO-OAT N/ water mixtures do not attack the sealing materials commonly used in heat pump technology.
Miscibility
STRUB GEO-OAT N is miscible with all commercially available antifreeze agents based on ethylene glycol. However, we recommend consulting our application engineering department before mixing STRUB GEO-OAT N with other products.
Application
STRUB GEO-OAT N is added to water in concentrations of at least 25 percent by volume (drinking water quality with max. 100 mg/kg chloride, or demineralized. Water) is added. If more than 60 % by volume of STRUB GEOOAT N is added, the frost protection is reduced.
For reasons of corrosion safety, the application concentration should not fall below 25 percent by volume. At lower concentrations, there is a risk of corrosion for the system due to underinhibition.
