Industrial fans take a significant share of total electricity consumption in the industry for their account. In addition, installations with fans are often subject to a high degree of vibration in the system. Maintenance or repair must be carried out regularly. Theses recurring cost are due to the nature of a fan installation. In ATEX environment, the cost of maintenance of fan installations increase rapidly and are often double to triple. Typically for fans are the high current peaks during the start of the installation. The non-contact magnetic coupling also provides a mechanical soft start preventing these current peaks. Often fans are indispensable in the production and cost of downtime can therefore be excessive.
In fan applications applying the magnetic coupling has many advantages. Significant energy savings could be achieved. In case of a mechanical error the damage to other equipment is prevented which reduces high costs for maintenance and repairs and avoids downtime. Applying the magnetic coupling means "FIT AND FORGET".
The Zytec magnetic coupling has no physical contact between the motor and fan shaft. This is connected through an air gap. There are no consumables such as bearings, seals and oil as in a fluid coupling with flexible coupling and is therefore maintenance free. Because the coupling transmits power without contact, no radial forces are generated on the motor shaft and fan shaft. This extends the service life of motor bearings to design life. Misalignment during operation is responsible for more than 50% of damage to rotating equipment. Alignment is no longer relevant with a contact-free magnetic coupling. The service life of the bearing to the fan shown in the film is therefore also significantly extended. In this case the vibrations due to the Zytec coupling were reduced by more than 60%. This means that the MTBR (Mean Time Between Repair) of the entire installation is therefore extended even further. There are even more advantages: no oil leakage, lower starting currents, shorter voltage dip, etc.

The occasions the mobile crane is needed for repair is significantly reduced.
