A SUITABLE FAN FOR EVERY REQUIREMENT – OUR ADVANTAGE
As a result of the large variety of our HRV programme it is possible to find a fan with high efficiency for almost every operating condition.

We modify the blade geometry to cater for specific dust compositions and burdens. We counter wear with different types of wear protection.

Blowers operating at practical load we equip with the less energy consuming air flow control devices.

CONTROL DEVICES : Energy saving & efficiency control devices
In Industrial process engineering plants the volume flowing is subject to the demands of the process operations. Exhaust and combustion air quantities are varied in accordance with the load on the steam producing plants or similar equipment. The selection and construction of the fans aims to achieve maximum efficiency throughout the operational range of the plant, particularly under partial load conditions. The adjustment of the overall efficiency to the actual operational neds frequently leads to large energy savings, particularly as a small reduction in the volume flowing results in a considerable reduction in the power absorbed. The combination of different method of varying the fan throughput, all automatically controlled by plant demand, should lead to the greater possible energy saving. This is particularly so in the case of variable speed drives as the power required varies as the 3rd power of the volume flow i.e at half volume flow the power demand is only one eighth of the original power.

FANS CONSTRUCTION : Leading differences are existing in the construction in respect of the inlet and bearings. The decision, whether a single or double width construction is necessary, is determined by the technical data. The impeller diameter, the impeller geometry and the speed have influence on the device of bearing. Double width fan impellers are generally constructed with a suction box (respt. With two suction boxes with the DHRV).
