Evans Aero Cool 180° är ett Vattenfritt fritt kylmedel som är godkänt för Rotax motorer enligt Rotax bulletin 912-043 RB & 914-029 R2

Fördelar...

Ingen överhettning

Evans Aero Cool 180° har en kokpunkt först över 180°C.

Ökad effekt

Evans Aero Cool 180° eliminerar för tidig detonation orsakad av överhettning.

ingen korrosion

Vatten innehåller syre, syre medför korrosion. Evans Aero Cool 180° innhåller inget syre vilket eliminerar korrosion.

Inget tryck

Evans Aero Cool 180° låter ditt kylsystem jobba under mycket lägre tryck, vilket reducerar påfrestningar på flera motorkomponenter.

No Liner Pitting

Evans Aero Cool 180° bidrar till avsevärt lägre risk för gropfrätning på cylinderfoder jämfört med vattenbaserade kylmedel.

 

Vetenskapen bakom Evans

Ingen Överhettning

Traditional water based coolants regularly cross the thermal boundary that separates Efficient Nucleate Boiling (A) from Inefficient Critical Heat Flux. CHF leads to localised film boiling (B) and steam bubbles circulating throughout the cooling system, which often results in overheating and combustion issues. Evans Waterless Coolants boil above 180º C ensuring effective cooling and efficient fuel burn is maintained for all engine loads and ambient air temperatures.

Ökad effekt

When water-based coolants vapourise adjacent to the combustion zone, hot-spots are formed. These hot-spots have been proven to cause pre-ignition in petrol engines and detonation issues in diesel engines. Evans Waterless Coolants eliminates hot-spots and subsequently improve combustion efficiency and increase power delivery.

Ingen korrosion

Water is the root cause of corrosion in all cooling systems, via oxidation (rusting) and galvanic (electrolytic) action. Evans coolants do not contain dissolved oxygen and have a much lower conductivity (increased resistivity) compared with water-based coolants. Subsequently replacing water with Evans non-aqueous solution eliminates corrosion and the need to periodically refresh or replenish the coolant.

Inget tryck

Water requires additional (cap) pressure to prevent it boiling within the engine. This additional pressure can vary between 7psi and 29psi (0.5 Bar to 2 Bar) which places significant stress on cooling system components, including hoses, gaskets and radiators. Evans Waterless Coolants generate much lower pressures, in the region of 4psi, and therefore reduces strain on all components.

Ingen gropfrätning

Liner pitting is primarily caused by the rapid formation and collapse of small steam bubbles on the metal surface. Over several years this process can lead to severe surface erosion and deep liner pitting. Evans Waterless Coolants are not prone to forming vapour bubbles and proven, by SAE trials, to virtually eliminate surface erosion and pitting.
