Applications

Many classic and vintage cars were designed in an era where today's density of traffic was an unseen nightmare and our motorways all too often resemble traffic jams resulting in engines which overheat all too readily. Engine damage can result and with parts becoming expensive or no longer available it can be essential to fit a Kenlowe secondary booster fan in preparation for using your classic on today's roads. Classic or historic car rallies in the U.K. and the hotter climates of Southern Europe increase the necessity for improved cooling. Use a Kenlowe thermo electric fan to provide insurance against damage caused by overheating on today's congested roads. Kenlowe thermo-electric fans are also available for use in place of the belt driven fan on vehicles with no history of overheating, to replace the original equipment electric fans fitted as standard on some classic cars in the 1960's, 70's and 80's.

Replica and Kit Cars
Many replica cars have special cooling needs because the radiator size or efficiency may not be as great as the original designed for the engine. In addition the air intake or exit from under the bonnet may be limited and a belt driven fan could be too far from the radiator to be efficient! All will lead to a cooling system which in high summer allows overheating! Use a Kenlowe fan for improved traffic cooling, around 8.5% power or fuel saving, a quicker warm up etc. Alternatively use the Kenlowe fan in addition to a belt driven fan for extra cooling. A Kenlowe fan is available for almost all replica cars.

Competition Cars
Rallies, trials and club meetings have created a wide range of specially modified road cars or purpose built competition cars. All have special cooling requirements. Kenlowe's wide range and extensive experience ensures a suitable model of Kenlowe thermo-electric fan is available.

Advantages

Over Cooling
Many vehicles running a fixed or viscous belt-driven engine fan fail to reach efficient working temperatures on long journeys, and on short journeys the engine can be so cold in winter that enrichment is needed throughout - any vehicle running a fixed or viscous belt-driven fan and no history of overheating can benefit by simply unbolting the fan (leaving the hub/pulley to drive the water pump) and fitting a KENLOWE thermo electric fan to provide cooling only when needed. The many advantages are significant and have been proven over 40 years, since the concept was first pioneered by the KENLOWE Group and which today is adopted as standard on over 80% of the world's production cars.

Improved Economy
Any engine driven auxiliary consumes power and the fixed or viscous fan is no exception. Research, initially by KENLOWE and subsequently by the specialised motoring press and the vehicle manufacturers, have established that significant fuel savings are achieved just by removing a fan that works all the time (including viscous fans) even though, on average, fan assisted cooling is only needed for around 4% of motoring time. The energy absorbed in driving the fan is not the only reason why around 8.5% fuel saving is available by removing the fixed or viscous fan - a much quicker warm up reduces the time to half, that the engine is on rich mixture (this also applies to fuel injected engines). Achieving a hotter more thermally efficient combustion is also an important aspect in the drive towards a fuel efficient engine.

More Performance 
It takes around 8.5% of the engine power output to drive a belt driven fan that is unnecessary for an average 96% of the time. Removal of the fixed or viscous fan means around 8.5% less fuel is needed for the same performance or around 8.5% extra power is available to improve performance. For example the energy used to drive the belt-driven fan on motorways or climbing in low gear at high revs is significant as the energy absorbed by the fan goes up by the cube of the speed. The belt-driven fan on almost all cars consumes around 8.5% of the total energy developed by the engine. On large 4x4 off-road vehicles that can be a lot of b.h.p. and all because the vehicle manufacturer had to assume the owner may cross the Sahara towing 2 tons morning, noon and night! Removal of the beltdriven fixed or viscous fan releases this power for safer overtaking, easier climbing and a more flexible and free revving engine.

Less Noise 
Belt driven fixed or viscous engine driven fans exist to provide artificial cooling in traffic when the engine revs are limited to tickover, which is why the size - diameter, pitch, width of aerofoil, etc. has to be large enough to compensate for the slow revs of the engine in traffic. Unfortunately, this means that when the vehicle is travelling on the open road and the fan speed rises in proportion to increased engine revs, the air roar from the fan increases until on the motorway the noise can become tiring and sufficiently intrusive to make conversation difficult. For example on a 4x4 off-road vehicle, removal of the belt-driven fan - not needed for 96% of the time, makes the vehicle noticeably quieter. Whilst viscous clutch fans slip a little at high revs this is usually at revs which equate to speeds well above 70 m.p.h. "Autocar" reported, during a test on a saloon car fitted with a KENLOWE fan, that the absence of fan noise makes any journey far less tiring!

Improved Comfort and Safety 
Belt-driven fixed or viscous slip clutch fans blow cold air over the surface of the engine during the first few miles of running from cold, doubling the time the engine takes to deliver comforting heat to the interior and warm air for effective demisting. In addition, whilst on choke or on fuel injected engines, during the period of enriched mixture, the engine is either over-revving or near to stall during those first few awkward miles from cold when most have to negotiate busy intersections. Removing the belt-driven fan ensures that warm-up can be up to twice as fast so that even short journeys can be safer and more comfortable!

Environment 
KENLOWE have promoted the fuel saving properties of thermo-electric engine-cooling fans in place of the continuous belt-driven fan, for over 40 years, resulting in a large number of vehicles made today being fitted with the KENLOWE concept as standard. This currently reduces vehicle gas pollution by nearly 10% per annum on over 85% of the world's car production which use the KENLOWE concept. However, there is still a number of vehicles produced, or running on our roads, with fixed or viscous belt-driven fans, wasting around 8.5% of the fuel used. This depletes world energy reserves and adds to pollution - particularly during the period from cold start to full operating temperature, when fuel consumption can be up to double that of a warm engine! In this condition up to half the fuel is passed unburnt into the atmosphere, after heating, as ozone damaging hydrocarbons.
