HD Nitrite Free RTU Coolant is common heavy duty diesel engine requirements. It incorporates organic acid technology to protect diesel engines from liner pitting and hard water scale deposits. Additional benefits include:
Provides up to 6 years / 600,000 miles / 12,000 hours of service without the need for extenders due to non-depleting organic acid technology.
Superior protection by organic acid technology to protect diesel engines from liner pitting and hard water scale deposits. The silicate and nitrite free extended life chemistry protects all cooling system metals from corrosion including aluminum.
Protects modern vehicles with aluminum engines as well as older vehicle models. It covers a wide application range including diesel engines, gasoline engines, stationary power, marine, natural gas, and light duty applications.
Compatible with major long life and conventional brands of ethylene glycol based coolant. However, long life characteristic may be diminished by mixing with light duty or conventional fully formulated coolants.
