Evans Waterless Coolants

‣ A proprietary blend, soluble additives, and no water.

‣ Boiling point: 375°F, Pour point: <-40° F/C.

‣ Evans are lifetime coolants if they do not become contaminated with water.

‣ Reduced toxicity

‣ Improves Fuel Economy

‣ Reduces Maintenance Costs

‣ Eliminates Replacement Expense

‣ Offers Environmental Advantages

‣ Increases Performance

Benefits of Evans Waterless Coolant

‣ Increase thermostat temperature to 205°F.

‣ Reduce fan-on time by raising fan-on temperature to 230°F.

The fans of heavy duty diesel engines draw considerable horsepower.Minimizing fan operation leads directly to significant fuel savings.

How Evans Waterless HDC Achieves Fuel Savings

Evans HDC Allows Two Fuel Saving Techniques for Heavy Duty Engines

‣ Recent fuel economy testing with a large US parcel company showed an overall improvement of over 3%.

‣ Fuel economy testing with Perdue Chicken showed an overall improvement of 5.5%.

‣ SAE Type II Test at PAVE Research Institute, using Evans waterless coolant with 215°F thermostats, proved a fuel economy improvement in excess of 3%.

‣ In early 2012 The NYC Dept of Sanitation completed a fuel economy/emissions program with ECS. Results were a fuel economy improvement of over 5% and a 4.3% reduction in CO22 emissions.

Demonstrated Fuel Savings

In a two year fuel economy study with Veolia Environmental Services, Evans Waterless Coolant has improved fuel economy by over 5%.

Reduces Maintenance Costs

‣ Waterless formula avoids corrosion and electrolysis.

‣ The absence of vapor reduces system pressure.

‣ No abrasive additive deposits.

‣ Pump seals hoses, gaskets will not deteriorate and last longer.

‣ Lengthens engine life by preventing pump and cylinder liner cavitation erosion.

ASTM Engine Cavitation Test

‣ The John Deere Engine Cavitation Test is now approved as an ASTM standard.

‣ The test was performed by Southwest Research Institute in April 2009 using Evans HDC.

‣ The results were 70% better than any other water-based coolant tested.

Eliminates Replacement Expense

‣ Evans waterless coolants are lifetime coolants; replacement costs are eliminated!

‣ Additives not required; Evans additives remain stable and in solution during storage and use.

‣ Occasional “topping off” not required. Evans waterless coolants will not evaporate.

Environmentally Friendly

‣ TOXICITY:Evans waterless coolants contain an inhibitor that lowers the toxicity of ethylene glycol – safe for animals. Thirteen states have recently passed laws requiring a bitterant to be added to antifreeze to reduce animal poisoning.

‣ DISPOSAL:Eliminates future disposal of old coolant.

‣ REDUCED EMISSIONS:Less fuel burned means less carbon dioxide emissions (for heavy duty diesel applications).

Performance and Reliability

Performance and durability are improved, prolonging the life of your engine.

Evans protects and preserves your investment in expensive equipment, whether it’s heavy duty or high performance.

Why is “Waterless” so Important?

What is good about water in a coolant?

Water has been the choice for cooling engines for over 100 years for very good reasons:

‣Water is cheap.

‣Water is available.

‣Water has superior thermal conductivity — in its liquid state.

What is Bad about Water in a Coolant?

‣ The low boiling point of water (212°F to 220°F) becomes the failure temperature of traditional cooling systems.

‣ Water is corrosive.

‣ Water retains just 4% of it’s thermal conductivity when it changes to vapor.

The energy that it takes to maintain coolant temperatures below the boiling point of water is a huge

waste of fuel.

Evans HDC Separates the Boiling Point of the Coolant from its Operating Temperature

‣ An engine operating temperature of 230°F is more than 100°F colder than the boiling point of Evans HDC.

‣ Cooling system continues to function after shut down:

No after-boil.Engine can be restarted at anytime.

With Evans HDC, the boiling point of water is no longer a limitation.

Boiling Point Comparison(Coolant Failure Temperature)

Thousands of successful conversions worldwide in applications ranging from cars to aircraft to generators

and heavy duty vehicles.

Most of these installations answer acute engine cooling problems that have defied solution by conventional

coolant means.

Versatility of Evans Waterless Coolants

Our Maiden Truck ConversionStill Going Strong!!

1. An Evans prototype coolant (predecessor of HDC) was installed into this truck when it was new (1990).

2. In 2012 the truck is still in daily use. For its entire history, it has had 215°F thermostats and a 230°F fan switch.

3. The truck is going strong with nearly 1,000,000 miles. Joe reports getting better than 7 mpg consistently during the entire period.

4. Head, cylinder liners, pistons and valves are original.

5. Joe takes satisfaction in driving past trucks that have triggered derating or shut-down at 225°F while his fan doesn’t even turn on until 230°F.

Rotax requires Evans waterless coolants for its small aircraft engines.

Previously, Rotax had a problem with take-offs in high ambient temperature regions. (The coolant would boil over before reaching cooler temperatures aloft.) The engines are used in small aircraft including the Predator uav.

Evans Waterless Coolant reversed Ferrari’s 16-year Formula One Slump

From 1983 to 1998 Ferrari never won the Constructors F-1 World Championship. In 1998, Maurizio Bollini, manager of engine cooling for Ferrari F-1 sought the guidance of Jack Evans, who taught him

how to use waterless coolants to increase the endurance of Ferrari’s race engines. Ferrari, beginning with the following year, won six

Constructors Champion-ships in a row.

Reserve capacity at 16,000 ft.

Qiang Xu, Evans’ agent in China, heard about construction problems with a new railroad project high in the Kunlun Mountains. At the elevation of 16,000 ft. the trucks could not carry full loads and required periodic shut-downs for cooling off. Xu converted a truck with Evans Coolant that had not been able to perform well at the high altitude. Afterward there was no boil-over despite full loads and no cool-off down-times.

Reserve Capacity made the generators in Iraq reliable when it was 140oF on the

tarmac.

The First Sergeant at the Balad Airbase near Baghdad requested help from Evans to keep the electricity running. His generators would automatically shut down at 225oF. They would not restart

without a 20 minute cool-down. An Evans coolant was installed and the 225oF shut-down thermostats were replaced with 250’s. The problems stopped – the electricity became reliable. Oil analysis

showed no issues.

Evans waterless coolants offer permanent solutions that save money and enhance

performance.
