Fluids used for heat transfer from devices to prevent overheating are called coolants. Coolants flow around or through devices for the transfer of the heat produced by the device to outer environment for heat dissipation. Industrial coolants absorb heat from the machine or engine and dissipate it by means of a radiator or other devices. Industrial coolants are also known as antifreeze liquids, which are generally a mixture of propylene or ethylene glycol with water mixed in an equal ratio. Industrial coolants also keep the passenger compartment of a vehicle warm. Anti-freeze liquids offer same properties as industrial coolants. Anti-freeze mixtures are more resistant to extremely low and high temperature. These liquids are concentrated products based on glycol with some corrosion inhibitors and other additives. Anti-freeze liquids are diluted in different proportions with additives to make industrial coolants of different grades. These diluted anti-freeze liquids are usually called industrial coolants.

Key properties of industrial coolants include low viscosity, high thermal capacity, non-toxic, low-cost, and chemical inertness. An ideal industrial coolant should not cause corrosion to the cooling system and other engine/machine parts. Majority of industrial coolants are used in various industries such as automotive, oil & gas, power generation, and chemicals. Industrial coolants must control the machine/engine temperature in all weather conditions without freezing or overheating. Special additives are added to industrial coolants to prevent chemical deterioration and freezing. Industrial coolants use special anti-corrosive additives to prevent internal corrosion of engine/machine parts in the automotive industry.

Three types of industrial coolants are used around the globe: green anti-freeze coolants, oat anti-freeze coolants, and HOAT anti-freeze coolants. Green anti-freeze coolants are the most common type of industrial coolants used around the globe. These coolants consist of phosphate and silicate additives, which provide protection to bare iron surfaces and aluminum parts of the machinery. HOAT anti-freeze coolants stand for organic acid technology. These types of industrial coolants contain organic acids such as sebacate, 2-EHA, and other various organic acids. HOAT anti-freeze coolants do not contain phosphates or silicates as found in green anti-freeze coolants. HOAT anti-freeze industrial coolants stand for hybrid OAT industrial coolants. These types of industrial coolants comprise organic acids with silicates and phosphates to provide protection for aluminum and metallic surfaces of machinery and engines. Most HOAT industrial coolants are used by car manufacturers around the globe.
