Bronswerk Heat Transfer - Reinvent the wheel

Any air cooler system needs to be as efficient as possible, with low energy consumption, high output and preferably low noise. That is exactly why Bronswerk Heat Transfer developed the innovative Whizz-Wheel solution. The company based the new fan on automotive and aeronautical technologies, and manufactures components with maximum quality and precision. As a result, the Whizz-Wheel fans emit 50% less vibrations when compared with conventional fans that have been balanced. This results in significantly lower maintenance costs and improved plant reliability.

The Whizz-Wheel offers maximum efficiency because of the ideal rotor design, its smaller hub and the aerodynamically shaped blades and twisted curves. The fan has no blade tips, no gap between the fan tip and the fan house, and additionally boasts a fan inlet of an optimised shape with increasing radius

Customers can deploy Whizz-Wheel-based equipment in greenfield projects. For example, it can be used for improving plant performance; reducing noise emission, power consumption and vibrations; minimising maintenance costs and increasing plant availability. The technology can be used in brownfield projects for the same purposes.

Dramatically increased performance

Air-cooled equipment is extremely sensitive to changes in airflow and ambient temperatures. Global warming, equipment ageing and more demanding processes have led to a need for increased performance. The Whizz-Wheel fan system can increase performance by up to 30%. Bronswerk Heat Transfer achieve this by using the high efficiency of its design and fully exploiting plenum recovery - 30-40% more air has a huge impact on thermal performance of existing coolers. For air-fin cooler sites, it is able to remove performance bottlenecks on summer days, allowing full production throughout the entire year. For air-cooled steam condensers, it yields year-round lower turbine pressure and more generator output.

The reduction of plot space

In offshore or brownfield applications, plot space is scarce. This is why the reduction of unit size is a major factor in reducing capital expenditure. The Whizz-Wheel fan system can save up to 30% on plot size, providing size and weight relief for all offshore or brownfield solutions. Less weight is particularly important in offshore applications. Every kilogram on the topsides requires 3-5kg in the substructure. The savings are enormous if taken on board in the early design of a vessel or platform.

The reduction of noise and power consumption

There is no longer the need to choose between less noise or reduced power consumption, as the Whizz- Wheel simultaneously delivers on all accounts. This aforementioned reduction is up to 50% lower power consumption and 20dB less noise respectively.

Customers are invited to speak to the Bronswerk Heat Transfer engineers to find out how the company can make the seemingly impossible happen. The Whizz-Wheel design is efficient, bringing down parasitic loads with no strings attached. The Whizz-Wheel is so silent that motor, transmission and even airflow noise become the dominant factor in noise calculation. This way the customer is guaranteed the lowest noise levels.
