Choosing the right fan is no easy matter for manufacturers of fan coils and fan coil units: As well as having to have the necessary output, operate quietly and be suitable for installation in the housing of the fan coil, the operating principle of the fan drive used also has to be appropriate to the requirements. After all, this has a decisive influence on how much energy is consumed and, therefore, the operating costs.
Ebm-papst has taken all these aspects into account – and even more besides. In the past, the operation of multiple fans in parallel used to be problematic due to disturbing harmonics. These are filtered by the specially developed active PFC (Power Factor Correction) optionally available from ebm-papst, and no further measures are then necessary to satisfy the harmonics-related requirements.
