When we design air-cooled coolers, we aim to find the optimal combination between costs, use of material, noise pollution and energy consumption. There is still plenty to learn about and improvements to be made to the interaction between air flow and pipe bundles in air-cooled coolers. This is why we have created an intensive research program over the last few years. One of the results is the development of a brand new fan, the Whizz-Wheel®.

• In recent years, Bronswerk® Heat Transfer has made serious investments to enable it to design
the world's most ultra low noise axial fans for air coolers: the Whizz-Wheel®.
• These fans are huge energy savers and therefore result in a considerable reduction of
operating costs. 'Considerable' in this case is also a euphemism for the gigantic dimensions of
the fans.
• The first test model for example, has a diameter of nearly four metres. We now design fans with
diameters that measure over ten metres!
• Since 1940, Bronswerk® Heat Transfer has been designing, producing and supplying heat
exchange installations that are used by companies such as Shell, Exxon Mobil, Texaco and
Siemens in the worldwide gas and oil industries and utilities.
• One hundred and fifty staff are employed in Nijkerk, with a further hundred abroad.
Bronswerk® has been growing over the last few years.
• We meet Guus Bertels; he is constantly looking for the latest developments, innovations and
breakthroughs.
• He has thirty years of experience in in the field; a real expert. Guus: "We create solutions for
problems that are so special, that existing techniques fail to perform.
• What we design must also work under the most extreme circumstances. From the Arctic to the
Antarctic, from the highest mountains to the deepest seas, from the wettest places to the driest
deserts, our solutions must perform under any conditions.
• We therefore invest heavily in knowledge/know-how and technology."
• How does this reflect in the design of Whizz-Wheel® fans? Guus: "It is a good example of the
innovative strength that we have.

• Traditional cooler fans are usually driven by gear boxes or v-belts. We looked for an
alternative.
• Eventually, we designed new drive concepts which enable the Whizz Wheel®fans to be
smaller, lighter and more quiet.
• They still comply to the strictest noise regulations and the efficiency of the shaft power has
been increased by over thirty percent.
• They are therefore the most ultra low noise and ultra efficient fans in the world. This allows
us to save a vast amount of energy.
