Sorry for the delay in replying but as you will see below Evans Response is quite detailed and lengthy. Posted below is the introduction only.
I have technical responses to all the No Rosion report so called findings. But I fear its to lengthy to post here. I have 8 pages all to gether. You wil find it posted on Meteor's Website or I am happy to email people.
I have the text below in a pdf if anyone would like a copy.
Evans UK - A detailed response to No-Rosion
Introduction and the need to respond ...
Evans Waterless Engine Coolants represent a major evolution in engine cooling technology and from NR's point of view a direct challenge to their business and 100 years of 'water-based' thinking. Inevitably there will always be contrary responses
when a revolutionary product or idea comes to the fore. Marconi, Edison and the Wright brothers all had their inventions scorned before they were accepted and whilst including Evans alongside such illustrious names could be considered indulgent,
the point we wish to make is clear. Evans would always urge potential adopters of any new technology to verify the facts with a suitably qualified source and be wary of commercially incentivised bias or hearsay.
Fortunately a significant number of individuals, race teams, fleet operators and manufacturers have taken the time to thoroughly and diligently evaluate Evans WEe. These include many well known and highly respected engine designers, builders, tuners
and restorers from the aeronautical, automotive, bike and heavy duty diesel sectors. Evans recent appointment as a technical partner to Honda and the use of Evans WEC in their engines provides another excellent point of reference and 'one in the eye'
for unqualified cynics and those with an axe to grind. To find out more about Evans technical partners, distributors and advocates please visit www.evanscoolants.co.uk
Evans usual strategy is not to engage with subjective forum hearsay or respond to documents that contain errors. Instead we prefer to focus our efforts on presenting detailed technical information, corroborated by hard-data and highly credible points of
reference, to those who are intent on making informed decisions. Unfortunately the NR document is doing the rounds and contains many inaccuracies mixed in with a few facts that have potential to cause confusion. So on this occasion we feel it is
prudent to flex this policy and quash their claims in a constructive manner.
Competence and Credibility aligned with Due Diligence ...
In 2011 Hydra Technologies Ltd. was appointed the UK licensee to manufacture and distribute Evans WEC throughout the UK, Europe and Middle East. HTLs core business is the formulation and manufacture of specialist heat transfer fluids, supplied to
OEMs, distributors and end users in the Refrigeration & HVAC, Solar Thermal & Geothermal sectors. HTL also designed, built, installed and operated large fluid processing equipment for Pepsi- Walkers and Co-Op dairies. Via its Marine & Offshore
Supplies division HTL has extensive experience in designing and packaging mechanical and marine equipment, including; engine driven generators and fire-pump sets, process cooling, filtration and fresh water systems.
Prior to establishing Evans UK HTL spent 14 months in due diligence reviewing all the data and test reports, collated by Evans USA over an 18 year period. Similar due diligence procedures were subsequently performed by Allianz (product liability
insurers) and UK Steel Enterprise division ofTATA (share holding investors). It would be reasonable to say, that none of the above mentioned companies would have proceeded if the product was flawed in the way NR purports.
Formulated from experience ...
Jack Evans and Tom Light, the men who perfected Evans WEC, are innovative mechanical engineers and their specialty had been the design of high performance engine cooling systems. For many years Jack and Tom improved pump and cooling
system design for a wide range of racing and production engines, working with Nascar, Ferrari, General Motors etc. During this investigative era they confirmed that water-based coolants were often restricting engine performance and operating outside
waters physical and chemical limits, even with additional pressure and inhibitors added. By replacing water with 100% glycol they eliminated the boiling and vapour issues, but were unable to remove sufficient heat energy to prevent a gradual increase in engine temperature. Over several years, experimenting with various glycols, synthetic and organic diols plus non-aqueous corrosion inhibitors, Jack and Tom formulated a patented WEC that; is non-toxic, has low viscosity, boils above 180°C, protects below -40°C, has low vapour pressure, doesn't retain dissolved oxygen and has very low electrical conductivity. All of these properties combine to ensure Evans WEC eliminate the boiling, corrosion and erosion issues associated to water-based coolants, whilst effectively cooling the engine.
Empirical versus theoretical...
Engineers often request Specific Heat, Thermal Conductivity and Viscosity data from us which is logical, but for Evans coolants can be misleading. Water has the best heat transfer characteristics (provided it is water not vapour) and theoretical calculations often indicate that using Evans will require a larger cooling system. This is the undoubted reason why OEM design engineers have persevered with water for all these years. In reality the 20 years of empirical data gathered by Evans proves
there is much more going on inside an engine cooling system than Q = M x Cp x ~T might suggest. Therefore we would always recommend testing Evans in a working engine to fully realise its extensive benefits.
