How it works
Exceeding the limitations of
water
Water is an excellent fluid for
cooling whilst in a liquid state, but when water turns to steam it has
virtually no capacity for heat transfer. Evans is a superior fluid for
transferring heat in engines because it remains in a liquid state until above
180°C. This article details the benefits of a significantly higher boiling
point.
Hot Spots
Within an engine cooling system
the hottest surfaces are those adjacent to the combustion chamber, specifically
the cylinder liners and cylinder head. In these hot spots water is likely to
vaporise preventing efficient cooling and causing loss of performance and
unnecessary engine damage (see physical limitations of water). When the coolant
fails in this way the engine becomes even hotter causing more hot spots and
more steam.
Evans waterless coolants will
not boil around these engine hotspots maintaining efficient cooling performance
even when the engine is put under extreme conditions. When water turns to steam
it pressurises the cooling system putting strain on hoses and other components.
The significantly higher boiling point of Evans coolants means 75% less
pressure than water resulting in a less stressed cooling system.
Technical
The Science of waterless cooling
Since the 1930's engine coolants
have been based on a mixture of ethylene glycol, water and corrosion
inhibitors. All such mixtures have inherent physical and chemical limitations
that restrict engine performance and affect reliability. Evans Waterless
Coolants represent a major step forward in engine cooling and engine protection
technology.
If you are treating an engine
that currently has coolant in it you will also need to purchase the Evans prep
Fluid also listed in our shop, information on the prep fluid can be found
below:
Absorbs Water
Before filling your system with
Evans Waterless Coolant it should be as free from water as possible. Evans Prep
Fluid hygroscopically absorbs any residual water remaining in the system after
draining.
System Flush
Evans Prep Fluid actively
removes the loose dirt and scale from your cooling system which can cause
inefficient heat transfer.
FAQ's
Q. Why does my vehicle need
Evans Waterless Engine Coolant?
A. Evans Waterless Coolants have
a boiling point in excess of 180°C which is far greater than traditional 50/50
coolants which boil around 103°C (at atmospheric pressure). Evans Waterless
Coolants also remove the threat of corrosion, electrolysis, liner pitting,
water pump cavitation, poor fuel detonation and over heating.
Q. What is Evans Waterless
Coolant made of?
A. Evans Waterless Coolants are
patented synthetic non-toxic liquids blended with a non-aqueous proprietary
inhibitor package.
Q. Which Evans Waterless Coolant
is correct for my vehicle or equipment?
A. Vintage Cool 180° is
specially formulated for increased yellow metal content and porous cast irons
found in Vintage engines.
B. Classic Cool 180° is
specially formulated for engines with more cast steel and iron, with reduced
levels of copper and the introduction of aluminum products.
C. Power Cool 180° is specially
formulated for high performance engines, with significant aluminium components.
D. Heavy Duty Coolant is
specially formulated for engines driving trucks, buses, plant etc. and contains
increased inhibitors to ensure an operating lifespan of 15 years or more.
Q. Will Evans Waterless Coolant
cause my engine to run at a higher temperature?
A. The operating temperature of
the engine and coolant may increase slightly, by approximately 3-7 degrees.
However the temperature inside the engine will be consistent and steam vapour
will not be produced. i.e engines often run cooler with Evans Waterless
Coolants.
Q. Can I add water to Evans
Waterless Coolant?
A. Yes, but only in an
emergency. Evans Waterless Coolant is completely miscible with Water, however
once you exceed 5% the benefits of Evans Waterless Coolant are compromised. We
recommend that as soon as possible you refill with Evans Waterless Coolant to
regain its benefits.
Q. Which engine coolants are
water-based?
A. All commercially available
engine coolants, (usually in a 50/50 water / coolant formulation).Evans
Waterless Coolant is the only non water-based coolant.
Q. What is the most important
operational feature of Evans Waterless Coolant?
A.The huge separation between
the operating temperature and the boiling point of the coolant, in the order of
at least 80°C.
Q. What is the primary purpose
of an engine cooling system?
A. To keep engine metal
temperatures under control.
Q. What is the difference
between Blue/Green and Red/Pink/Orange coolants?
A. Colour, there are however
some general industry guidelines;
A. Most blue/green coolants have
non OAT (organic acid technology) inhibitors, contain silicates and phosphates
in their inhibitor package and should be changed every two years.
B. Most red/pink and orange
coolants contain OAT inhibitors and can last three to five years.
C. From the 1990,s most
manufacturers have started using HOAT (hybrid organic acid technology). HOAT
based coolants can last three to five years. These have no particular colour
scheme. (The above three products must not be mixed together).
Q. Does the colour of Evans
Waterless Coolant products indicate any difference within the formulation of
the Coolant?
A. Yes, All Evans Waterless
Coolant is based on a proprietary inhibitor blend, the colour denotes the
formulation specific to vehicle type.
A. Green denotes a Classic
Formulation
B. Purple denotes a Vintage
Formulation
Q. How do the OAT additives in
Evans Waterless Coolant remain in solution without the presence of water?
A.Evans Waterless Coolant
contains no additive that requires water to dissolve or to enable the additive
to function
Q. How long will Evans Waterless
Coolant last?
A. 4LIFE, Evans Waterless
Coolant will last the life of the engine as long as it is not contaminated with
water.
Q. What is bad about water in a
coolant?
A. The boiling point of water is
only 100°C.
B. Because an engine operates
very close to the boiling point of water,(within the engine block and cylinder
head boiling actually occurs), thus causing pressure within the cooling system.
C. The boiling point of water is
the failure temperature of the cooling system.
D. Water vapour (steam) has
almost no thermal conductivity.
E. Water is aggressive toward
cooling system metals and promotes electrolysis between dissimilar metals
within the cooling system.
F. Water contains Oxygen which
encourages corrosion in any cooling system.
Q. Water-based coolant is mostly
50% glycol and 50% water. Why isn’t the critical temperature the boiling point
of the mixture, rather than the boiling point of water?
A. The critical temperature of a
mixed solution will always be the boiling point of the weakest solution, water
turns to steam vapour and is the weakest solution in the mixture, Some
locations within the cylinder head generate so much heat that some of the
nearby coolant boils. When local coolant boils, the resulting vapour is nearly
100% water vapour. If the coolant that is surrounding the water vapour is above
the boiling point of water, the water vapour cannot condense. Under this
condition, the water vapour makes an insulating barrier between hot metal and
liquid coolant, causing the temperature of the metal to spike to high levels.
Q. Why is the vapour from
boiling a 50/50 glycol/water mixture (EGW) nearly 100% water vapour?
A. When the mixture is boiled
the water part is fractionally distilled, as it is far more volatile than the
glycol portion. Water vapour is liberated while the glycol remains in the
solution.
What are various boiling points
of interest?
A. Water at sea level (1 atm.
absolute) boils at 100°C.
B. Water at sea level with a 1
atm. pressure cap (2 atm total) boils at 121°C.
C. EGW at sea level (1 atm.
absolute) boils at 106°C.
D. EGW at sea level with a 1
atm. pressure cap (2 atm. total) boils at 128°C.
E. Evans Waterless Coolant
Waterless Coolant at sea level (1 atm. absolute) boils at 180°C.
What happens to the boiling
points at higher elevations?
Boiling points decline as altitude
increases.
A. Water at 5000 ft. (0.83 atm.
absolute) boils at 97°C.
B. EGW at 5000 ft. (0.83 atm.
absolute) boils at 103°C.
C. Evans Waterless Coolant at
5000 ft. (0.83 atm. absolute) boils at 176°C.
Do I use the same volume of
Evans Waterless Coolant in my cooling system as before?
Yes, Evans Waterless Coolant
thermally expands to within 1% of 50/50 water based coolants at 100°C so you
can use the existing fill level in your cooling system for Evans Waterless
Coolant.
What is pump cavitation and how can
it occur?
A. Action of the coolant pump
creates a low pressure area at the pump inlet. Pump cavitation occurs when
coolant near its boiling point encounters the low pressure area and flash
vaporises (creates steam) within the pump. The gas pocket in the pump causes
the pump to stop functioning and coolant circulation to stop. Coolant pump
cavitation leads directly to catastrophic cooling system failure with the
coolant being expelled from the system as steam pressure exceeds the pressure
relief setting of the cap.
What is after-boil?
A. After-boil occurs after
shut-down of a stressed engine when the coolant is near its boiling point and
residual heat remains in the cylinder head. Upon shut-down the coolant pump
ceases to circulate coolant through the cooling system. Residual heat boils the
stagnant coolant, making steam pressure that exceeds the pressure relief
setting of the cap. Coolant is pushed out of the system.
What unique limitations are
there on a functioning cooling system using any water-based coolant?
A. The cooling system must keep
the coolant below the boiling point of water depending on the pressure of the
system, under all operating conditions and after shut-down. This task is
difficult because the coolant frequently operates close to or at the boiling
point of water.
What is the Reserve Capacity
made available by changing to Evans Waterless Coolant?
A. The huge separation between
the operating temperature and the boiling point of Evans Waterless Coolant
unlocks a Reserve Capacity that already exists in systems designed for
water-based coolants. Any cooling system designed to keep coolant below the
boiling point of water depending on the pressure of the system under all
operating conditions and after shut-down is liberated from those requirements
with Evans Waterless Coolant. When temperatures happen to be higher, there are
no failures due to the lower boiling point of water. In a 38°C environment
(under bonnet) a radiator that is 121°C will dissipate 25% more heat than one
at 104°C.
How does Evans Waterless Coolant
prevent after-boil?
A. After shut-down, the huge
separation between the operating temperature and the boiling point of Evans
Waterless Coolant has the capacity to absorb heat from hot metal parts of the
cylinder head, boiling is avoided and there is no build-up of pressure to force
coolant out of the system. Stresses on cylinder heads are also avoided as metal
temperatures are kept under control.
How does Evans Waterless Coolant
prevent engine hot spots?
A. The huge separation between
the operating temperature and the boiling point of Evans Waterless Coolant
provides an environment where any locally generated coolant vapour immediately
condenses into adjacent liquid coolant. vapour cannot then build into an
insulating barrier, and contact between hot metal and liquid coolant is
maintained at all times. Metal temperatures remain under control at all times.
How does Evans Waterless Coolant
prevent pump cavitation?
A. The low pressure area of the
coolant pump is never at a low enough pressure to flash vapourise. The pump
never gets vapour bound and has the capability to pump coolant over a broad
range of temperatures.
How does Evans Waterless Coolant
prevent cylinder liner cavitation erosion?
A. Cylinder liner cavitation
erosion is a problem in water-based coolant systems. As the piston moves inside
the cylinder there is vibration of the liner. The vibration of the liner
against the coolant alternately makes low and high pressures. During the low
pressure instant, vapour is created by flash vaporisation. During the adjacent
high pressure instant, the vapour collapses against the cylinder liner. This
repeated action causes an attack against the metal liner, resulting in
cavitation erosion. Evans Waterless Coolant contains no water to allow flash
vaporisation and therefore removes the threat of cylinder erosion.
Do I have to add antifreeze to
the Evans Waterless Coolant?
A. No, Evans Waterless Coolant
has an antifreeze protection built in to protect to -40°C.
How much water is acceptable
after a conversion to Evans Waterless Coolant?
A. In all conversions, ideally
water content must not exceed 3.0%.
How do you test for the
percentage water content?
A. The water content is readily
determined by the use of a refractometer .The following are refractometer
readings of Evans Waterless Coolant with corresponding water content percent:
R.I. Reading: Evans Waterless
Coolant
1.43181 0% Water by volume
1.43085 1% Water by volume
1.42986 2% Water by volume
1.42935 3% Water by volume
1.42882 4% Water by volume
1.42749 5% Water by volume
What will happen if I do not
achieve the recommended 3% water content?
A. Even at above 3% water
content Evans Waterless Coolants will still out perform all traditional water
based coolants. However for high performance and arduous conditions full
benefit may not be realised. If the conversion guidelines are followed, rarely
does the water content exceed 3%.
Is Evans Waterless Coolant
toxic?
A. No, Evans Waterless Coolants
contain Evans patented DeTox™ additive and has been classified as Non-Toxic by
an EPA certified laboratory. However as with all chemicals, do not consume.
Keep away from children. Avoid contact with eyes and skin. Rinse hands and eyes
with water after incedental contact.
What should I do with the old
coolant out of my vehicle?
A. Traditional
antifreeze/coolants are toxic and should be disposed of in accordance with the
local regulations.
