New wall fan tested and optimised for the Asian market
In 2020, SKOV launched a new wall fan in the BlueFan family called BF 50. It is a 50-inch box fan – a perfect solution for both newly built houses and as a replacement fan in existing houses.
Before launching new products, SKOV always ensures that the product is tested in relevant production environments to ensure that the customer receives quality products.
Amco Group, which has a pig production farm of 2,800 sows close to Bangkok in Thailand, has for more than 20 years been one of SKOV’s trusted partners for testing before launching new products.
“It is essential for a company like ours to constantly keep up with new technologies and optimise our farm equipment so that we can deliver high-quality piglets and fattening pigs at low production costs,” Mr Suphanut Jiebna says, Operations Director of Amco Group. The BF 50 fan is a 50-inch box fan that fits into the existing fan holes needing replacement. Likewise, you can often reuse the existing electrical installation and controller.
Able to withstand harsh environments
“Replacement of the traditional box fans with BF 50 took place without problems – both in terms of any mechanical and electrical challenges,” Mr Suphanut continues. Traditional box fans, made of galvanised metal, require replacements at regular intervals due to corrosion as they are exposed to the harsh environment in the livestock house.
In contrast, the new wall fan is made of thermoplastic and stainless steel – non-corrosive materials that, by far, better withstand the harsh environment in a modern livestock house. “Our experience is that traditional box fans must be replaced approximately every 4 years as they rust. Since the new wall fan is made of plastic, we expect a much longer service life, as plastic is not affected by the harmful substances in the exhaust air,” Mr Suphanut says.
Optimal climate and animal welfare
The new wall fan combines minimum energy consumption with a high airflow ratio. The pressure-stable design enables the fans to run efficiently under all weather conditions. It always ensures optimum climate conditions in the livestock house.
“Furthermore, the motor and fan blades are directly connected. There is no driving belt or other moving parts that require replacement and adjustment at regular intervals,” says Mr Suphanut. For optimised climate and animal welfare, Amco Group has chosen the BF 50 with motor-controlled shutters. The motor-controlled versions ensure that the position of the shutter, even at a strong wind, remains in its correct position. It also enables the use of an emergency opening. “Our experience is that the centrifugal clutch, which opens the shutter in traditional fans, must be replaced at 12-16 month intervals. We avoid this replacement here,” Mr Suphanut says.
The shutter is insulated and closes tightly, protecting against condensation and false air intake when the fan is not running. “We did not collect data about energy consumption for BF 50 versus other fans, but it immediately seems that in our setup, it is at least as energy-saving as similar energy-optimised fans on the market,” Mr Suphanut concludes.
The fan can be regulated according to the Dynamic MultiStep principle.
“Tests in large poultry houses in Oceania show a 35-50% reduction in power costs compared to traditionally ventilated houses. When the new fan is used in combination with the Dynamic MultiStep, the customer gets the most energy-efficient ventilation system on the market,” says Mr Rasmus Ellefsen, SKOV Managing Director Asia.
Multiple benefits of the new wall fan
The BF 50 is the new generation of wall fans, setting new standards for outstanding performance, remarkable efficiency, and low wind susceptibility. The savings on electricity costs using the Dynamic MultiStep option with the new fan ensure a quick return on investment and an ongoing reduction in energy consumption.
