Reliable cooling is a continuous requirement but cooling fans running without interruption consume a lot of energy. With the product series ZAplus, Ziehl-Abegg was able to offer several improvements to the existing system. The newly placed cooling fans have Electronically Commutated (EC) motors which are proven to be highly energy efficient and environmentally friendly. The practical design of the fan allows easy maintenance and improves uptime guarantee. The use of EC-Technology will result in a significant reduction of the energy use and the bionic profile of the blades (inspired by the owl) minimizes noise pollution to the surrounding area. Altogether, the new fans will help BritNed to lower its energy consumption by 450.000 kWh per year and reduces its carbon footprint by 51 tons per year. Improved efficiency is not the only benefit that the ZAplus fans bring to the energy operator. To improve the uptime the fans are equipped with a special service ring which enables easy access for maintenance and repair. The whole cooling unit does no longer need to be turned off for maintenance, so expensive outages will be reduced. Before the replacement cleaning took two weeks, now it takes one day. The replacement of the 40 fans took place in two batches during planned outages. Kevin Rendell, BritNed’s Operations Director, praised Ziehl-Abegg’s swift and userfriendly installation of the new fans. The old cooling fans will be recycled.
