Proguard HDD Coolant is a heavy duty full formulation hybrid anti boil/anti-freeze coolant with nitrite chemistry recommended for use in heavy duty diesel engines and light duty diesel. It is a combination of organic technology corrosion inhibitors with conventional heavy duty chemical inhibitors common to USA technology for compliance with Cummins, Detroit and CAT equipment that contain low silicate, nitrite, nitrate and molybdate. The technology used in this coolant is suitable for typical measuring techniques.
Proguard HDD in concentrate form contains 90% monoethylene glycol and a heavy duty inhibitor package ensuring ultimate corrosion protection and extended service life when compared with conventional coolants. Proguard HDD contains extreme levels of rust and corrosion protection in combination with advanced coolant technology to provide a superior quality coolant. Proguard HDD protects all metals found in cooling systems and gives excellent protection against “hot spot” corrosion common in aluminium cylinder heads, diesel engine wet sleeve liner pitting and eliminates hard water scale deposits. Proguard HDD is suitable where SCA filters are recommended or required and has no deleterious effects on hoses, silicon seals or gaskets.
This product is coloured Red or Blue.
Proguard HDD is recommended for use in marine engines, earthmoving, mining, bus companies, heavy transport and commercial fleet operations. It has a service life of up to 6 years / 1,000,000 kms in heavy duty diesels. Service intervals are 1 year / 4,000 hours. There are obvious environmental advantages as a result of fewer coolant changes.
This product is typically used as a 50/50 mix with demineralised water.
