It’s important to have an engine coolant that is useful year-round, regardless of temperature, and Keller-Heartt can help. We carry ShellZone Dex-Cool and ShellZone Multi-Vehicle antifreeze single-gallon cases and 55-gallon drums in both concentrated and 50/50 dilated mixtures to fit your production.
Good for 150,000 miles or five years, ShellZone Dex-Cool is used for gasoline and diesel engines that do not require nitrite. Its ethylene glycol formula contains a carboxylate inhibitor system similar to other Shell coolants, providing thermal protection to aluminum, brass, solder, steel, copper, and other metal surfaces.
In addition to Dex-Cool coolants, our ShellZone Multi-Vehicle Extended Life Antifreeze is great for any temperature between -34° and 256° Fahrenheit. ShellZone coolants not only perform well, but they also possess a long shelf life and are 100% biodegradable in their unused form.
