The new Extended Life Coolant (ELC)
is recommended for use in on- and off-road heavy-duty equipment, as well as stationary applications, requiring a nitrite-free OAT formulation, as mandated by engine manufacturers like Detroit Diesel. In 2006, Detroit Diesel published DDC 93K217, which only allows the use of nitrite-free extended life coolants (OAT) in its engines. Delo Extended Life Coolant/Antifreeze - Nitrite Free helps ensure operators meet OEM warranty requirements.
Delo Extended Life Coolant/Antifreeze - Nitrite Free offers a service life of 600,000 miles, 12,000 hours or six years with no chemical extender needed.
Other benefits of the new Delo ELC-NF include: corrosion protection and lower electrical conductivity; protection against pitting, corrosion and erosion even on hard-to-protect metals like aluminum; superb heat transfer compared to silicate containing coolants; improved water pump life due to its silicate-free formula.
DELO ELC-NF is 100 percent compatible with DELO ELC, which contains nitrite. Like other extended-life coolants in the Delo line the new nitrite free ELC product is dilution tolerant up to 25 percent.
