EC axial fans for agricultural ventilation

The new EC axial fans for agricultural ventilation Energy-efficient fans are also becoming increasingly important in agriculture. Motivated by legal requirements and increasing energy costs, the market is demanding new, energy-efficient solutions. To accommodate this trend, ebm-papst has introduced the new axial fan series with energy saving EC technology, fully in line with the GreenTech philosophy. This brochure contains a selection of axial fans, starting from an outer diameter of 500 mm all the way up to an outer diameter of 1250 mm. This corresponds to an air performance of up to...

Energy comparison: axial fans size 800 The controlled ventilation of agricultural sheds is carried out primarily using axial fans. The fans are driven using single-phase asynchronous motors installed in the hub, with speeds that are adjusted by changing the supply voltage. The disadvantage of this system is the relatively poor energy balance. New motor and control configurations provide a significant improvement in energy balance. The following comparison between a conventional asynchronous fan and a GreenTech EC fan demonstrates this impressively. External rotor technology External voltage...

Energy comparison: axial fans size 800 GreenTech EC fan provides significant cost savings. This is shown in the If both fans are operated over the year with the specified load profile, the following image as a function of the energy costs. For example, if the electricity price is 0.10 EUR per kWh, annual savings of 149 EUR can be Electricity rate The following figure provides the view over a longer period. Here, the Figure: Annual savings as a function of the energy costs annual operating costs of both fan concepts are added up over the years. The load profile shown above also served as the...
