2 In many production processes, the work area must be exposed to a uniform flow of air or gas over the entire width. The flow-through principle In a tangential fan, the air is drawn in over the entire length of the fan impeller. Inside the impeller the airflow is diverted and accelerated by the vortex created by the rotation of the impeller. The airstream then exits over the entire length of the impeller on the discharge side. The vortex separates the intake and discharge side of the fan at the narrowest point between the impeller and the vortex builder. Together with the fan scroll the vortex...

6 LTG Engineering Services Process Air Technology Successful cooperation with clients from many industries Power modules for amplifiers as they are used in mobile communication systems, must be cooled evenly for trouble- free operation and long life. To avoid heat accumulation, the emitted heat must be removed from the enclosure. Tangential fans series TA 25, 40, 60, allow for a low height of the enclosure and keep the noise levels to a minimum. Plastic bottles Printed/varnished parts such as plastic bottles have to be dried and cooled off before further processing. For a consistently good drying...

7 LTG Engineering Services Process Air Technology Successful cooperation with clients from many industries Steel parts After forging, the red-hot steel parts are annealed with ambient air. To achieve the required hardness and therefore material strength it isessential that air is blown evenly on all parts and that certain annealing curves are adhered to. Tangential fans series VQ meet these criteria. They produce an absolutely even airflow over the entire work area. Plastic bumpers Parts, such as plastic bumpers, are tested in a test cabinet where they are subjected to certain temperature cycles....
