A coolant is a fluid which flows through a device to prevent its overheating, transferring the heat produced by the device to other devices that use or dissipate it. An ideal coolant has high thermal capacity, low viscosity, is low-cost, non-toxic, and chemically inert, neither causing nor promoting corrosion of the cooling system. Some applications also require the coolant to be an electrical insulator.
- Rapid Cool Long Life: Express Long Life Coolant is developed to protect engines of both ferrous and aluminium construction against corrosion and frost damage. Provides protection to radiators, cylinder blocks, heads and water pumps
Performance: IS 5759 : 1994.
- Rapid Cool Concentrate: Express COOL CONCENTRATE is a fully synthetic, watersoluble coolant concentrate. Its ingredients passivate the various materials and provide long-term protection against corrosion. When mixed with water, COOL CONCENTRATE is a very efficient coolant with
a specific heat
Performance: IS 5759 : 1994, JIS K 2234-1994
