Chevron Introduces HDAX® Prediluted 40/60 Extended Life Coolant/Antifreeze09:00 EDT Tuesday, May 15, 2012 SAN RAMON, Calif. (Business Wire) -- Chevron Lubricants, maker of technologically advanced engine oils, lubricants and coolants, today introduced its new HDAX® Prediluted 40/60 Extended Life Coolant/Antifreeze. The product, designed for use in heavy-duty stationary natural gas engines that require improved heat transfer performance and long-life cooling system protection in a wide range of operating conditions, is formulated with Chevron's patented carboxylate corrosion inhibitor technology. Up to 17% Improved Heat Transfer The silicate free formula found in HDAX Prediluted 40/60 Extended Life Coolant/Antifreeze can deliver up to 17% improved heat transfer when compared to traditional 50/50 coolants using silicates. This improved heat transfer results in fewer high temperature engine de-rating events or shutdowns. The product's phosphate free properties help to reduce the occurrence of hard water and phosphate scale on heat transfer surfaces such as liners, hoses and radiators versus high phosphate (typically containing 3000ppm or greater of Phosphate) containing heat transfer fluids or coolants. “Increased engine performance coupled with reduced maintenance is at the top of the wish list for all operators of heavy duty stationary natural gas engines,” said Jim Gambill, North America Industrial Lubricants and Coolants Brand Manager. “Our new HDAX Extended Life Coolant helps to deliver improved performance and reliability our customers need to operate at maximum efficiency while protecting key engine components.” Reduced Operating Costs The extended life formula helps to reduce the need for Supplemental Coolant Additives (SCA), resulting in less SCA purchases and fewer maintenance checks. HDAX Prediluted 40/60 Extended Life Coolant/Antifreeze is excellent for operations where stationary engines are in remote locations, or are periodically moved from job site to job site and coolant maintenance is sporadic. Excellent Protection HDAX Prediluted 40/60 Extended Life Coolant/Antifreeze helps deliver effective, long term corrosion protection, even at the elevated temperatures commonly found on cooling system metals. The product is effective at protecting against liner cavitation and pitting and helps to maximizes water pump seal life due to its silicate-free, phosphate-free formulation. Extending Service Life HDAX Prediluted 40/60 Extended Life Coolant/Antifreeze may provide up to 32,000 hours of stationary engine coolant life when following OEM coolant maintenance recommendations and maintaining a correct 40/60 dilution ratio. For 32,000 hour life operations, always ensure the system is topped-off with HDAX Prediluted 40/60 ELC and take coolant samples every 6 months to check for coolant dilution. Should dilution occur, add either HDAX Prediluted 40/60 ELC or Chevron's Fleetfix Maintenance product to maintain appropriate coolant system protection. The product has been field tested with stationary gas engine operators who reported excellent long-life performance, superb cavitation protection and low maintenance costs. Testing was conducted in various engine models including Caterpillar and Waukesha stationary gas engines operating in severe conditions. HDAX® Prediluted 40/60 Extended Life Coolant/Antifreeze meets or exceeds ASTM D6210 and D3306, and is suitable for use in stationary gas engines manufactured by: Ajax Caterpillar Cooper-Bessemer MWM Wartsila Waukesha White Superior HDAX Prediluted 40/60 Extended Life Coolant/Antifreeze is biodegradable in its unused form and can be stored for a minimum of 8 years as purchased.
