Kenlowe only supply fans to vehicle manufacturers/engineering companies and field replacements for existing specialist applications. We no longer make or supply thermo electric fan packages for retrofit on individual cars for the automotive aftermarket.
Kenlowe have been proud of our history as originators of electric engine cooling and delivering serious cooling demanded for today’s conditions. However, whilst size matters, amps are often even more important.
With the industry quoting airflow performance in free air (i.e. without a radiator in the way) amps is often the only way of showing if cooling performance will be strong or weak when the radiator is included in the equation.
Selecting the largest diameter to cover the most area of the radiator is a good aim, but if the amps are low, so will the airflow exiting the radiator. Its exit airflow that the heat travels away on, not entry airflow, so if you have twice the amps you can achieve twice the cooling.
Amps on larger diameters fans should be double or treble the amps of smaller diameter fans, larger diameter fans taking similar amps to much smaller diameter fans will not perform as expected when used for cooling a radiator.
All radiators represent a restriction to airflow throughput and whilst some radiators are thin, most fast road cars, classic cars, competition cars or 4 x 4’s have thicker radiators which have the potential to disperse more heat. However, you can only realise that potential with a high performance fan and amps is the best indicator of that.
With some vehicles having multiple radiators – intercoolers, oil coolers, air conditioning condensers etc. it is even more essential to have a high amp fan to get enough air out of the other side of the water radiator. Additional radiators add heat and resistance to air which reduces cooling performance significantly.
