Reduces fuel consumption by up to 9%
The Waterless Engine Cooling System is proven to reduce fuel consumption by up to 9%. For HGVs covering considerable motorway mileage, fuel savings of 4 to 8% can be expected. Engines used in slow moving and semi-static environments, where ram air cooling is negligible, can achieve fuel savings in excess of 9%. Detailed corroborative data is available on request.
Lasts an engine lifetime
Evans Waterless Coolants are formulated to last for the lifetime of an engine. Water based coolants have to be periodically drained and replaced, involving vehicle maintenance time and materials expense. Evans Waterless Coolants eliminate all these demands.
Eliminates need for coolant top-up
Waterless Coolant does not boil over, eliminating the need for constant top-up.
Prevents corrosion to cooling systems
Water is the root cause of cooling system corrosion and why excessive doses of corrosion inhibitor are required. Evans Waterless Coolants contain no water, effectively eliminating all corrosion.
Increases Engine Efficiency = more BHP
Operating at higher temperatures is proven to improve engine efficiency and reduces the fan-on time, freeing more power to be used for traction.
Significant reduction in exhaust emissions
The Department for Transport states that, for every litre of diesel fuel burned 2.6 kilos of CO2 and other noxious gases are produced. Improving the fuel consumption of a typical HGV from 7.5 to 7.81 MPG over 100,000 miles can decrease CO2 emissions by 9800 kilos.
Improves cylinder liner durability and reliability
Water based coolants are prone to forming steam bubbles on the surface of engine liners. When these steam bubbles collapse a pit is generated in the liner. Over time these pits get very deep and are a known cause of liner failure. An independent test, carried out in accordance with SAE procedures, confirmed that Evans Waterless Coolants generated significantly less pitting when compared with all other leading brands of coolant. Please ask for a copy of the test report.
Low Pressure Cooling minimises hose failure
To prevent premature boil-over conventional engine cooling systems are fitted with a spring loaded cap, which effectively raises the cooling system pressure to 14.5psi (1 Bar) above atmospheric pressure. This extra 14.5psi is very often the cause of burst hoses. Evans Waterless Coolants only generate 2-4psi cooling system pressure and effectively eliminate burst hoses.
No more over-heating or after-boil
Water based coolants are prone to boil when an engine is operating at full power. And the additional 14.5psi cap pressure is often insufficient to prevent coolant loss and subsequent over-heating and after-boil. Evans Waterless Coolants have a boiling point above 180°C at atmospheric pressure and will not boil over.
Proven Non-Toxic to animals
Traditional coolants are based on Ethylene Glycol (EG), water and corrosion inhibitors. EG is toxic and kills 1000's of animals every year. Dogs and cats are especially prone because they like the taste without realising its effect. Accidental and deliberate human fatalities are also common. Evans Waterless Coolants contain a DeTox additive which renders it non-toxic to animals. Human liver trials are in progress and Evans expects positive results in 2011.
Anti-Freeze protection down to -40°C
Evans Waterless Coolants provide anti-freeze protection down to -40°C. Below this temperature Waterless Coolants form crystals that have no expansive force thus eliminating the risk of engine damage.
Frequently Asked Questions
Which engine coolants are water-based?
All commercially available engine coolants, except Evans coolants, are water-based.
What is good about water in a coolant?
Water is cheap. Water in the liquid state has excellent thermal conductivity characteristics.
What is bad about water in a coolant?
The boiling point of water is too low. There is very little separation between the operating temperature of the coolant and the boiling point of water for the pressure of the system. The boiling point of water is the failure temperature of the cooling system. Water vapor has almost no thermal conductivity. Water is aggressive toward cooling system metals and promotes electrolysis between dissimilar metals within the cooling system.
Water-based coolant is mostly 50% glycol and 50% water. Why isnât the failure temperature the boiling point of the mixture, rather than the boiling point of water?
Some locations within the cylinder head generate so much heat that some of the nearby coolant boils. When local coolant boils, the resulting vapor is nearly 100% water vapor. If the coolant that is surrounding the water vapor is above the boiling point of water, the water vapor cannot condense. Under this condition, the water vapor makes an insulating barrier between hot metal and liquid coolant, causing the temperature of the metal to spike to high levels.
Why is the vapor from boiling a 50/50 glycol/water mixture (EGW) nearly 100% water vapor?
When the mixture is boiled the water part is fractionally distilled, as it is far more volatile than the glycol portion. Water vapor is liberated while the glycol remains in the solution.
What are various boiling points of interest?
Water at sea level (1 atm. absolute) boils at 212° F.
Water at sea level with a 1 atm. pressure cap (2 atm total) boils at 250° F.
EGW at sea level (1 atm. absolute) boils at 224° F.
EGW at sea level with a 1 atm. pressure cap (2 atm. total) boils at 263° F.
Evans Waterless Heavy Duty Coolant at sea level (1 atm. absolute) boils at 375° F.
What happens to the boiling points at higher elevations?
The boiling points decline as the altitude increases.
Water at 5000 ft. (0.83 atm. absolute) boils at 207° F.
EGW at 5000 ft. (0.83 atm. absolute) boils at 218° F.
Evans Waterless Heavy Duty Coolant at 5000 ft. ( 0.83 atm. absolute) boils at 368° F.
What is pump cavitation and how can it occur?
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 vaporizes 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 Afterboil?
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 or in an auxiliary circuit such as an EGR cooler. 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 is the primary purpose of an engine cooling system?
To keep engine metal temperatures under control.
What burden must be uniquely borne by a functioning cooling system using any water-based coolant?
The cooling system must keep the coolant below the boiling point of water for the pressure of the system under all operating conditions and after shut-down. This task is difficult because the coolant frequently operates close to the boiling point of water.
What is the most important operational feature of Evans Waterless Heavy Duty Coolant?
The huge separation between the operating temperature and the boiling point of the coolant, on the order of at least 100° .
What is the Reserve Capacity made available by changing to Evans Waterless Heavy Duty Coolant?
The huge separation between the operating temperature and the boiling point of Evans Waterless Heavy Duty 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 for the pressure of the system under all operating conditions and after shut-down is liberated from those requirements with Evans Waterless Heavy Duty Coolant. When temperatures happen to be higher, there are no failures due to the lower boiling point of water. In a 100° F environment a radiator that is 250° F will dissipate 25% more heat than one at 220° F.
Is Evans advocating operating engines at substantially higher temperatures?
Not really. Operating temperatures are normally only slightly warmer than those of water-based coolant. When the engine is stressed and temperatures rise, the cooling system can accommodate that increase in temperature without cooling system failures.
How does Evans Waterless Heavy Duty Coolant prevent engine hot spots?
The huge separation between the operating temperature and the boiling point of Evans Waterless Heavy Duty Coolant provides an environment where any locally generated coolant vapor immediately condenses into adjacent liquid coolant. Vapor cannot build into an insulating barrier, and contact between hot metal and liquid coolant is maintained at all times. Metal temperatures are under control at all times.
How does Evans Waterless Heavy Duty Coolant prevent after-boil?
After shut-down, the huge separation between the operating temperature and the boiling point
of Evans Waterless Heavy Duty 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 and EGR heat exchangers are avoided as metal temperatures are kept under control.
How does Evans Waterless Heavy Duty Coolant prevent pump cavitation?
The low pressure area of the coolant pump is never at a low enough pressure to flash vaporize. The pump never gets vapor bound and has the capability to pump coolant over a broad range of temperatures.
How does Evans Waterless Heavy Duty Coolant prevent cylinder liner cavitation erosion?
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, vapor is created by flash vaporization. During the adjacent high pressure instant, the vapor collapses against the cylinder liner. This repeated action causes an attack against the metal liner, resulting in cavitation erosion.
How does Evans Waterless Heavy Duty Coolant save fuel?
In spark ignition engines Evans Waterless Heavy Duty Coolant saves fuel by better control of metal temperatures and the avoidance of hot spots. The consequent reduction of knock permits more efficient spark settings on engines having electronic controls with knock sensing inputs. In heavy duty engines having on-off fan clutches, the âonâ temperature can be increased to 230° F, keeping the fan off a large percentage of the time and reducing a significant source of parasitic drag.
How long will Evans Heavy Duty Coolant and its additives last?
Evans Waterless Heavy Duty Coolant will last the life of the engine as long as it is not contaminated with water.
How do the additives in Evans Waterless Heavy Duty Coolant remain in solution without the presence of water?
Evans Waterless Heavy Duty Coolant contains no additive that requires water to dissolve or to enable the additive to function.
How much water is acceptable after a conversion to Evans Waterless Heavy Duty Coolant?
In heavy duty diesel applications the water content must not exceed 3.0%. Dry engine installation of Heavy Duty Coolant is preferred.
How does one test for the percent water content?
The water content is readily determined by the use of a refractometer (Evans Part. No. E2190).The following are refractometer readings of Evans Waterless Heavy Duty Coolant with corresponding water content percent:
Brix Reading: Water Percent
55.70: 0
55.00: 1
54.70: 2
54.40: 3
54.00: 4
53.50: 5
How do you calibrate the refractometer?
Using a drop of new Evans Waterless Heavy Duty Coolant, adjust the Brix reading to 55.70.
Evans Waterless Heavy Duty Coolant contains a blend of glycols, including ethylene glycol, which is toxic. How toxic is Evans Waterless Heavy Duty Coolant?
Evans Waterless Heavy Duty Coolant contains a substance that inhibits the metabolism of ethylene glycol, preventing its toxic metabolites from forming. In tests on rats according to EPA regulations, no rats died eating Evans Waterless Heavy Duty Coolant, even in quantities that completely filled the stomachs of the rats, indicating a very low oral toxicity.
If Evans Waterless Heavy Duty Coolant is so low in oral toxicity, why is there an ethylene glycol warning on the bottle?
The U.S. Consumer Products Safety Commission requires the ethylene glycol warning on all products that contain over 10 percent ethylene glycol. Permission to waive the labeling requirement requires tests on human tissue that have not yet been performed.
How much power does the radiator fan for a typical heavy duty engine use?
According to the Cummins MPG Guide (February 2007), the fan for an ISX engine draws 17, 26, 37, and 52 HP at 1300, 1500, 1700 and 1900 RPM, respectively. (Fan horsepower relates to RPM by Fan Law #3.)
At what temperatures do the fans for heavy-duty engines turn on and turn off?
Typically, the fans turn on around 200° F-210° F and off between 180°F and 190°F.
Why are fan temperatures set so low?
Fan temperatures are typically set low enough so that water based coolant can act as a heat sink to absorb residual heat, preventing an afterboil situation, at idle or shut-down following a stressful run.
Do low fan temperatures cause the fan to run more of the time?
Yes, low fan temperature settings cause extended âfan-onâ intervals as compared to higher fan temperature settings. Heat transfers more efficiently from a hotter radiator to the ambient air than from a cooler radiator. The fan does not have to run as long to transfer the same amount of heat.
Obviously, running the fan less will save fuel. How can Evans Waterless Heavy Duty Coolant be used to reduce âfan-onâ time?
There is ample capacity for the coolant to absorb residual heat from both the cylinder head and the EGR cooler without causing boiling and other after-boil problems. With Evans Waterless Heavy Duty Coolant the fan-on temperature can be safely increased to, say, 230° F, reducing the âfan-onâ time. Keeping the radiator fan âoffâ more of the time reduces fuel consumption significantly.
How is the âfan-onâ temperature raised?
There are no internal hardware or software changes to the engine control module (ECM). A coolant temperature sensor (thermistor) that is similar to the one in use is tested to determine its resistance v. temperature profile. The additional resistance that would be required for the fan to turn on at 230° F is computed. A ResistorPac of that value is placed in series with the coolant temperature sensor. Evans Cooling Systems, Inc. is happy to provide further information or guidance on request. The fan will then turn on at 230° F.
The fan is needed for functions other than for controlling coolant temperature. What happens to the charge air temperature and the head pressure for the a/c system when the input signal to the ECM is altered for the coolant temperature?
The fan will still respond to the conventional settings for charge air temperature and for the a/c head pressure. Typically, these functions do not require nearly as much fan as required for maintaining coolant temperatures.
Can higher temperature coolant thermostats be used with Evans Waterless Heavy Duty Cooling for additional gains in fuel economy?
Yes. SAE Type II testing was performed by the PAVE Research Institute at Auburn University that proved a 3 percent improvement in fuel economy with Evans waterless coolant and 215°F thermostats.
Are there additional requirements for using 215°F thermostats?
The fan-off temperature must be increased so that the coolant does not have to be cooler than 215°F for fan-off.
