    Key Considerations

    Whether you refer to them as coolants or antifreeze, selecting the correct product is vital for operational efficiency. Key performance factors such as pH stability, cavitation protection, inhibitor longevity, and resistance to oxidation directly affect pump performance, heat exchange efficiency, and the overall lifespan of your equipment. Industrial engines and closed-loop systems rely on specialized coolant formulations that maintain low viscosity, resist deposit formation, and provide long term corrosion control under heavy mechanical load. 

    Univar Solutions offer a range of concentrates and premixed coolants suitable for automotive, heavy-duty, commercial, and industrial engines requiring long-life protection be that with our own Caflon product range or OEM approved grades. 

    With purity, safety and efficiency to consider, it is imperative that you trust the quality of the engine coolants you use in your business, as well as rely on your chemical distributor for accurate, on-time service, customer support and supply chain expertise. Backed by reliable supply chain capability, technical expertise, and consistent delivery performance, we help businesses maintain system uptime and meet strict maintenance schedules. Univar Solutions is the ideal business partner to meet your technical specifications, and service requirements.

    Industrial Coolant FAQ's

    What is industrial antifreeze and why is it essential?

    Coolants (or antifreeze) help to protect engines and closed‑loop systems from freezing, overheating, corrosion, cavitation, and scale formation, helping maintain long‑term performance and system reliability. 

    What are the differences between ethylene glycol (EG) and propylene glycol (PG) antifreeze? 

    Ethylene glycol antifreeze provides strong freeze protection and heat transfer performance, while Propylene glycol (PG) antifreeze offers similar benefits with lower toxicity for specific applications. Both deliver dependable thermal stability when manufactured to high‑purity standards. 

    How do I choose the right industrial antifreeze / coolant for my equipment?

    Selection depends on:

    • Glycol antifreeze base (EG vs PG)

    • Required freeze point / boiling pointprotection

    • Adherence to required industry standard certifications

    • Inhibitor technology (OAT antifreeze, HOAT, IAT, nitrite‑free)

    • Engine material of construction(e.g.aluminium, steel, copper, cast iron)

    These factors determine long‑term corrosion control and system compatibility.

    What performance characteristics should I look for in a coolant other than temperature control?

    Key performance indicators include pH stability, inhibitor longevity, cavitation protection, oxidation resistance, low viscosity, and resistance to deposit formation. These directly affect equipment lifespan and cooling efficiency.

    What types of systems or applications use industrial antifreeze?

    Industrial antifreeze is used in:

    • Light passenger, transportation and heavy duty vehicles

    • Industrial engines

    • Commercial equipment

    • Closed‑loop cooling systems

    • Automotive systems requiring long‑life corrosion and freeze protection

    What are the different inhibitor technologies available?

    These are corrosion‑inhibitor packages:

    • INORGANIC / IAT (Inorganic Acid Technology) – IAT coolants offer a traditional, mineral based inhibitor package, often imparting upto 2 years worth of corrossion protection

    • OAT(Organic Acid Technology) – OAT coolants offer long‑life protection, often up to 5 years, based on an organic inhibitor package

    • HOAT (Hybrid Organic Acid Technology) – HOAT coolants offer mixed organic/inorganic protection

    • Si-OAT (Organic Acid Technology with added silicate) - beneficial for aluminium based engines where silicates impart added corrossion protection

    • P-OAT (Organic Acid Technology with added Phosphate)- specifically formulated for Asian branded vehicles. P-OAT impart long life protection, particulalry for aluminium engines, helping protect against cavitation

    • PSi-OAT (Organic Acid Technology with added Phosphate and Silicate)- supplements the performance of a Si-OAT with added Phosphate, to help boost cavity protection

    What metals are coolants compatible with?

    Our antifreeze coolant formulations, certified to rigourus industry standards inclusive of corrosion testing against ASTM D1384, ASTM D2809 and ASTM D6210, are compatible with aluminium, steel, cast iron, copper alloys, and solder, ensuring safe use in modern and legacy equipment.

    Do coolants come premixed or as a concentrate? 

    Coolants are available in concentrate or premixed options depending on system requirements. Concentrates allow custom dilution, while premixed versions offer convenience and dosing accuracy.

    How does the use of coolants help reduce maintenance issues?

    By preventing scale, corrosion, cavitation, and inhibitor depletion, industrial antifreeze helps maintain system uptime, lowers repair frequency, and supports long‑term equipment protection.
