Evans Waterless Coolants are proprietary coolants that do not use water. They have a higher boiling point than water-based coolants and remain stable without water. Testing has shown Evans Waterless Coolants can improve fuel economy by 3-5%, reduce maintenance costs, and eliminate coolant replacement expenses while providing environmental advantages over water-based coolants. The document provides various examples of applications where Evans Waterless Coolants have improved engine performance and reliability in trucks, aircraft, generators, and Formula One racing.

water.
‣ Reduced toxicity

3. ‣ Improves Fuel Economy

‣ Increases Performance
Benefits of
Evans Waterless Coolant

4. ‣ 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.

5. ‣ 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

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

7. 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.

8. 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.

9. 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.

10. 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).

11. 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.

12. 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.

13. 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.

15. 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.

17. 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.

18. Our Maiden Truck Conversion
Still 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.

19. 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.

20. 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.

21. 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.

22. 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.

23. Evans waterless coolants offer permanent
solutions that save money and enhance
performance.

Performance Advantages!!
