HD EXTENDED LIFE RTU AFC

ZEREX HD Nitrite Free Extended Life Coolant (ELC) is registered to Cummins CES-14603, conforms to ASTM D6210, and is suitable for common heavy-duty diesel engine requirements. This fully formulated Nitrite Free ELC uses organic acid technology to protect diesel engines from liner pitting and hard water scale deposits. The silicate and nitrite-free chemistry protects all cooling system metals, including aluminum, from corrosion. It can also be used in gasoline engines, stationary power, marine, natural gas, and light-duty applications. ZEREX Nitrite Free ELC offers up to 10 years / 1,000,000 miles / 20,000 hours of service without extenders due to non-depleting organic acid technology and is backward compatible for all cooling systems using OAT coolants.
