Frigutec® HDC for heavy-duty engines is a modern low silicate coolant concentrate with the latest low silicate Si-OAT corrosion protection technology combined based on monoethylene glycol and a nitrite additive for the best possible cavitation protection.
Frigutec® HDC has been specially developed for heavy-duty cast iron diesel engines operating under special operating characteristics with a long duty cycle at or near the maximum rated conditions. Such engines are typically used in off-highway machinery for agriculture, mining, earthmoving, construction, high power stationary engines, locomotives, and marine engines.
Frigutec® HDC is free of 2-ethylhexanoic acid, borate, phosphate, and amines. We recommend Frigutec® HDC only for vehicles where nitrite containing coolants are specified according to ASTM D4985 and ASTM D6210. For all other heavy-duty engines, we recommend to use our Frigutec® OAT-EVO.
