Chevron’s Delo brand of engine oils, lubricants and coolants has introduced the latest member of its product family, Delo Extended Life Coolant/Antifreeze-Nitrite Free (DELO ELC-NF).
The new extended-life coolant 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 manufactures like Detroit Diesel. In 2006, Detroit Diesel published DDC 93K217, which allows only the use of nitrite-free extended-life coolants in its engines. Delo Extended Life Coolant/Antifreeze-Nitrite Free is formulated to help 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, the company says. Other benefits of the DELO ELC-NF, according to Chevron Products, include: excellent corrosion protection and lower electrical conductivity; exceptional protection against pitting, corrosion and erosion, even on hard-to-protect metals like aluminum; superb heat transfer compared to silicate containing coolants; and improved water pump life due to its silicate-free formula.
DELO ELC-NF is formulated to be 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.
“Not only does our new product meet the needs of OEMs requiring the use of nitrite-free OAT coolants, it also provides maximum protection of the six basic metal alloys found in most heat transfer systems,” says Carmen Ulabarro, indirect channel manager for San Ramon, Calif.-based Chevron Products Co. “As a global leader in coolant technology, Chevron has a product line that successfully balances the needs of both the OEMs and the customers. Our ELC products help maintain OEM warranties while providing customers the performance they need to drive bottom-line value.”
In addition to extended-life coolant products, Chevron Products also has taken the lead in the development of field tests for its extended-life coolants, Ulabarro says. “I believe that our newest field test is a great improvement over our previous field test kit and will give Chevron customers the added security of knowing that the Chevron formulation has not been overdiluted with conventional or fully formulated coolants or water.”
Chevron Products says Delo Extended Life Coolant/Antifreeze-Nitrite Free — which currently is available in North America in pails, drums and bulk and soon will be offered in gallon jugs — meets or exceed the requirements of the following: Detroit Diesel/MBE; Cummins; MTU; European OEMs like Volvo; Japanese OEMs like Komatsu; ASTM D 3306, performance requirements of ASTM D6210 and TMC RP 329; and OEMs requiring a nitrite-free extended-life coolant based on carboxylate technology.
A new Texaco extended-life coolant, known as Texaco Extended Life Coolant/Antifreeze-Nitrite Free, also has been made available by Chevron Products. Texaco Extended Life Coolant/Antifreeze-Nitrite Free also meets the Detroit Diesel coolant specification 93K217 and offers identical performance characteristics to the new Delo product, the company says.
