Commercial Transportation Antifreeze/Coolants
Delo® Extended Life Coolants dramatically simplify the way cooling systems are maintained and deliver optimum engine performance. Our patented organic corrosion inhibitors eliminate the need for supplemental coolant additives and maximize hardware performance and heat transfer over the life of your engine.
DELO® 1000 MARINE 40
Product description
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.

Customer Benefits
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.
Applications
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
Features
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.
Delo ELC Antifreeze/Coolant products are recommended for use in a wide variety of cooling system applications including on-road, off-road and stationary engine applications. These products are also recommended in mix fleet applications where heavy duty and light duty trucks are present. Please check your OEMs coolant recommendations.
DELO® 1000 MARINE 40
Product description
Delo® XLC is a non-nitrited extended life Antifreeze/Coolant formulation for heavy duty and light duty diesel vehicles and equipment. Delo XLC is formulated with an aliphatic corrosion inhibitor system available as a concentrate and a premix 50/50.

Customer Benefits
Delo XLC Antifreeze/Coolant products deliver value through:
- Optimal Service life — Service life of 960,000 kilometers/12,000 hours/ 6 years with no Extender needed
- Excellent Protection — Excellent protection against pitting, corrosion and erosion even on hard to protect metals like aluminum.
- Minimized maintenance and related costs — Requires no regular testing with proper top-up practices and helps eliminate the need for supplemental coolant additives.
Applications
Recommended applications for Delo XLC Antifreeze/Coolant:
- Heavy duty engines regardless of fuel type or environmental controls being used where the OEM recommends a nitrite free, silicate free coolant.
- Mixed fleets where automobiles, light duty trucks and heavy duty trucks are being serviced and the OEM recommends a nitrite free, silicate free product.*
Features
Delo XLC Antifreeze/Coolant is a heavy-duty, ethylene glycol based engine coolant which incorporates patented organic corrosion inhibitor technology called aliphatic carboxylates. Delo XLC is a nitrite, nitrate, borate, phosphate, silicate, and amine- free formulation that provides maximum protection of the six basic metal alloys found in most heat transfer systems. Delo XLC products do not contain phosphates or silicates which are known to contribute to hard water scale issues. Delo XLC promotes maximum water pump seal life by eliminating inorganic corrosion inhibitors. Delo XLC has a recommended service life of 960,000 kilometers/12,000 hours/ 6 years. This product will not require the addition of SCA’s to achieve its recommended service life. Routine visual inspections, coolant top-off and annual testing are recommended to ensure maximum service life.
Note: These products are not to be used to protect the inside of potable water systems against freezing.
