Evans Coolant® – NPG Waterless Engine Coolant

Universal NPG Waterless Engine Coolant by Evans Coolant®. Evans NPG coolant is ready to use – no water required. It contains no silicates or phosphates and requires no Supplemental Coolant Additive (SCA). For tracks or in series where propylene glycol-based coolants are allowed. Evans NPG waterless coolant, is recommended for racing engines that run on tracks or in series where propylene glycol-based coolants are allowed but there is a “No Ethylene Glycol” rule. NPG can be used in high performance street vehicles with high flow cooling systems, as well as for food service equipment where ethylene glycol products are contraindicated. NPG is not recommended for daily drivers or cold weather operation, and may require system modifications to ensure a successful conversion.

Evans® Cooling Systems, Inc. pioneered the first commercial waterless engine coolants and has provided non-aqueous engine coolant products to the marketplace for over 20 years.These coolants feature very low vapor pressures and boil at 375°F. The operating temperature of an Evans coolant is always much colder than its boiling point, preventing boil-overs under conditions that can cause water-based coolants to fail. Evans coolants prevent engine hot spots by keeping liquid coolant in contact with all of the hot metal surfaces of the engine coolant jacket at all times. By avoiding water in the coolant, Evans protects against insulating pockets of water vapor, as well as against water-caused corrosion and cavitation erosion. Electrolysis is minimized because Evans waterless coolant has less than one third the electrical conductivity of water-based coolant. By ending boil-overs, Evans coolants expand the acceptable operating temperature range of the coolant, providing a reserve cooling capacity for any liquid cooling system.Evans Cooling Systems has four issued and current U.S. patents for engine coolants as well as additional U.S. patents pending. Patents have been granted to Evans Cooling corresponding to the U.S. patents by a number of foreign countries, including China, India, and Japan. Patent applications corresponding to the latest U.S. filings are pending in foreign countries, as well. Evans is committed to continued research and development of waterless engine coolants to seek further improvements and to strengthen its intellectual property. Evans’ corporate and marketing office is in Suffield, CT, and its sales and distribution office is located at Pottstown, PA.
