Cat® ELI™ (Extended Life Inhibitor) is a long-lasting coolant for marine and industrial engines working in environments that do not experience freezing temperatures. Cat ELI uses an active protection technology, similar to Cat ELC™, that avoids the problems experienced with conventional coolants and supplemental coolant additives (SCA) mixed with water. In fact, the organic additives in Cat ELI can target specifically the cooling system surfaces that are susceptible to corrosion. This advanced chemical technology delivers superior protection, improved cooling system efficiency, and has lower impact on the environment.

Benefits:

Lowers your cost
  • Uses less coolant: ELI lasts three to six times longer than conventional coolants or commercial supplemental coolant additives (SCA) mixed with water
  • Reduces maintenance costs due to less frequent checks of coolant health and less replacement of inhibitors
  • Reduces number of coolant drains/ flushes
Lowers your downtime and repair cost
  • Superior corrosion protection and effective heat transfer
Superior protection of your coolant system
  • Protects aluminum, brass, copper, iron, steel, etc. from pitting and corrosion
Lower impact on the environment
  • No glycol in the formula
