Evans specialty NPG high performance waterless coolant, EC10064, is specifically designed for racing venues that allow propylene glycol based coolants, but not ethylene glycol and food service equipment where ethylene glycol products are contraindicated. Evans waterless coolants have a boiling point above 375 degree and will not vaporize, eliminating overheating, boil-over and after-boil, while generating very low vapor pressures reducing strain on engine cooling system components. Contains no oxygen, effectively eliminating corrosion, liner and cooling pump erosion, resulting in reduced maintenance costs. Eliminates pre-ignition and detonation caused by overheating, reducing downtime, improving combustion efficiency, and delivering more power. Provides low temperature freeze protection with a freezing point below -40F. Evans NPG is the original waterless coolant and is a lifetime coolant. NPG is recommended for racing engines that run on Tracks or in series where there is a "no ethylene glycol" rule, and can be used in high performance street vehicles with high flow cooling systems. NPG is not recommended for daily drivers or cold weather operation, and may require system modifications to ensure a successful conversion. Evans prep fluid should be used to ensure All residual water is removed from the system before adding Evans waterless coolant.
HOW IT WORKS
Water is an excellent fluid for cooling as long as it remains in a liquid state, but when water turns to steam it has virtually no capacity for heat transfer. Evans waterless coolant is a superior fluid for transferring heat in engines because it remains in a liquid state until above 375Â°Fâ€”well above the operating temperature of an engine.
Within an engine cooling system, the hottest surfaces are those adjacent to the combustion chamber, specifically the cylinder liners and cylinder head. These hot spots cause water to vaporize, preventing efficient cooling and causing loss of performance and unnecessary engine damage. When the coolant fails in this way the engine becomes even hotter, causing more hot spots and more steam.
Evans waterless coolants will not boil around these engine hotspots, maintaining efficient cooling performance even when the engine is put under extreme conditions. When water turns to steam it pressurizes the cooling system, putting stress on hoses and other components. The significantly higher boiling point of Evans coolants means significantly less pressure than water, resulting in a less stressed cooling system.
Water contains oxygen, which causes corrosion and also allows electrolytic activity which further damages engine metals. Evans waterless coolants eliminate corrosion and electrolytic activity, significantly increasing the life of the engine.
