RAVENOL HTC Hybrid Technology Coolant Concentrate is an all-season, mono-ethylene glycol–based coolant developed using hybrid inhibitor technology, combining silicates with Organic Additive Technology (OAT).
The formulation is amine- and phosphate-free and is designed to provide corrosion protection and frost protection when mixed with water at the correct ratio. The hybrid inhibitor system supports long-term protection of cooling system components and is suitable for use in all-aluminium engines as well as mixed-metal cooling systems.
RAVENOL HTC Coolant Concentrate is suitable for use in a wide range of automotive applications where this coolant technology is specified. In addition to vehicle use, it is also suitable for approved auxiliary applications such as geothermal probes and collectors where the relevant approval applies.
