Delo ELC Antifreeze/Coolant

Delo® ELC Antifreeze/Coolant products are single phase, ethylene glycol based products available in various dilutions that are based on patented aliphatic carboxylate corrosion inhibitor technology specifically formulated for heavy duty cooling system applications that require nitrite.


Delo ELC Antifreeze/Coolant products deliver value through:

  • Managing costs
    Helps eliminate the cost of using SCAs (supplemental coolant additives), regular testing and the manpower required to perform these tasks effectively eliminating those costs when compared to conventional or fully formulated coolants. 

  • Long Service Life
    1,250,000 Kilometers of on-road use (8 Years or 15,000 hours of off-road use) or 1,600,000 kilometers/20,000hours/8 years with Delo Extender addition at 800,000 kilometers/10,000 hours/4 years.

  • Optimal cooling system operation
    The silicate free formula improves heat transfer when compared to silicate containing formulations. Silicates deposits can reduce heat transfer and increase downtime due to over-heating. 


  • Delo ELC Antifreeze/Coolant products are heavy duty engine coolants that use a patented organic corrosion inhibitor technology called aliphatic carboxylates. Delo ELC is free of nitrates, borates, silicates, phosphates and amines. These products contain nitrites and molybdates for additional cylinder liner protection.


Recommended applications for Delo® ELC Antifreeze/Coolant products:

  • Heavy duty engines regardless of fuel type or environmental controls being used where the OEM recommends a silicate free, extended life coolant that contains nitrites.

  • Mixed fleets where both light duty and heavy duty trucks are present.

  • Stationary engine applications regardless of fuel type being used.

  • Marine cooling systems where freeze protection is needed and a nitrite containing coolant is recommended.
