07-13-2009: Evans Reports That Focus on Lowering Fuel Costs Is Driving Innovation In Engine Cooling Technology

Evans Waterless Coolant Offers a Fuel Saving Strategy For Diesel Engines

SUFFIELD, Conn., - July 13, 2009 - Evans Cooling Systems, Inc., developer of the only waterless engine coolant, reports that the increased focus on achieving fuel savings is driving advances in engine cooling technology.

"As fuel prices continue to increase, everyone from fleet managers to individual owner operators of diesel trucks continue to look for ways to save fuel and, ultimately, money, and Evans sees this as a driving force in engine cooling innovation," said Mike Tourville of Evans.

One aspect of diesel engine operation that is often overlooked when it comes to fuel savings is the cooling system, but a significant amount of fuel is used to keep the engine cool, reducing mileage, engine efficiency and power.

Independent testing has proven that Evans' cooling technology can achieve fuel and maintenance savings, all while providing a more environmentally friendly solution.

The key to Evans Heavy Duty Thermal Coolant, a patented, waterless technology, is a boiling point that is 150 degrees warmer than the operating temperature of most engines, allowing the engine to safely operate at slightly higher temperatures. The huge separation of the boiling point from the operating temperature enables two fuel saving strategies:

• Raising the thermostat temperature to 215°F
• Raising the fan-on temperature to 230° and fan-off temperature to 220°F.

Raising the fan-on temperature is critical, since the fan on a heavy duty diesel engine draws a considerable amount of horsepower, decreasing fuel efficiency. Any reduction of fan-on time will, therefore, save fuel. In a long-term test with a Mack MR688S engine, retrofitted with Evans coolant and raising the fan-on temperature to 230°F, results showed an overall improvement of over 7 percent!

Evans coolant also offers benefits to users such as preventing overheating, corrosion, liner cavitation, and multiple maintenance issues typically related to cooling system failures. In addition, Evans thermal coolant is a lifetime coolant which never needs replacement.

In separate tests performed by an independent laboratory, the John Deere Cavitation test, researchers found cylinder liner cavitation was significantly reduced when Evans HDTC was used for cooling. The lower cooling system pressure maintains a virtual hermetically sealed system and reduces stress on cooling system plumbing and hoses.

"The John Deere test results show that Evans Waterless HDTC lengthens the life of the engine by preventing corrosion and pump and cylinder liner cavitation, resulting in major maintenance savings," said Tourville. "Because HDTC has no water, damage to metal, hoses, and gaskets by electrolysis is avoided."

Evans waterless engine cooling technology is in use in numerous fleets currently, with trials in process with major carriers worldwide.
