Radiator Coolant Additives

Designed to provide simplicity to the blender

The basic requirement of an engine coolant is to transfer heat from the internal combustion engine to the radiator, where the fluid is cooled by means of airflow.

Hence a coolant that provides longer protection against freezing & boiling is preferred. A large number of materials are used in the modern cooling system including steel, copper, aluminium, solder, cast iron, brass, plastics and numerous types of elastomers. An engine coolant typically consists of a base fluid and an additive package made up of mostly corrosion inhibitor additives.


SPEL Radiator Coolant additives are effective for use in all types of coolants that meet these complex requirements of vehicles of all makes and models.

  • Organic Inhibitors (OAT- Organic Additive Technology) such as carboxylates.
  • Mineral (also called inorganic) inhibitors such as silicates, borates, nitrites and phosphates.
  • Hybrid Package with combination of both organic & inorganic

SPEL Radiator Coolant Additive package helps the industrial equipment deliver superior performance by protecting them from rust, sludge and scale deposits and any contamination in the radiator.

The package offered by SPEL can be added to coolant either as a liquid, powder or charge inside a filter to fortify the coolant’s anti-corrosive and other desirable properties. This ease of application coupled with the high performance makes it suited for a wide range of applications.

These additives are processed by using corrosion inhibitors in its composition to ensure perfect protection to equipment from rust attack. We see its wide application in huge chemical and bio-chemical plants. The product which we cater under Coolant Additives are Diethylene Glycol, Glycerine, Coolant Corrosion Inhibitor etc.


SPEL radiator coolant additives are designed for chemistries based on diethylene glycol, glycerine, coolant corrosion inhibitors etc.
