Labyrinth seals - Import export

For the conveying of gaseous materials. Gas-tight fans If the conveying medium of a fan must not be allowed to penetrate to the outside (e.g. gases that are harmful to health), our fans are equipped with a multi-chamber labyrinth seal on the shaft gland. Depending on requirements, the seals are provided with a sealing gas connection or a grease seal. Under certain circumstances the sealing gas can also be connected to the suction side of the fan. Naturally the flange connections are sealed accordingly and the fan housing is welded gas-tight and tested.

The unrestricted availability of energy is playing an increasingly important role. Highly efficient gas or diesel generators, so-called gensets, are used as power generators, e.g. as emergency power generators in hospitals or as temporary power suppliers in areas that are difficult to access. Another area of application is large data centres, where the unrestricted and uninterrupted availability of electricity must be guaranteed. Gensets ensure the power supply in any situation, even under extreme conditions. Our genset gearboxes are connected between the motor and the generator, so that a frequency adjustment for the required power grid is achieved. It is possible to adjust the frequency from 50Hz to 60Hz as well as from 60Hz to 50Hz. The speed transmission is highly efficient, as the single-stage spur gears guarantee a high efficiency of >99%. The use of a labyrinth sealing system also means that the drives require very low maintenance.
