Flexibility is the trump card. That's why EC centrifugal blowers from ebm-papst can be expanded in modules. Even connecting fans in parallel is no longer a problem thanks to the active PFC. The result is that virtually every customer requirement can be fulfilled.
See for yourself: The new EC centrifugal blowers from ebm-papst start up faster than conventional EC models, whilst at the same time offering much quieter operation and greater energy efficiency. The "heart" of this speedy starter, available in fan sizes 160 and 250, is a GreenTech EC motor with a power of 0.75 kW. The graph on the right shows the time required to run up to maximum speed with an applied control voltage of 10 V.
Air curtains are used wherever cold air needs to be separated from warmer air. In just a matter of seconds, they generate a wall of air that prevents cold air from mixing with the warm air in adjoining areas, for example in cold storage rooms or at goods reception.
In air locks, a strong air flow is quickly generated to decontaminate clothes in no time at all. This is where the EC centrifugal blowers developed by ebm-papst show just how superior they are: They start up at least as quickly as conventional AC versions, but with far greater energy efficiency, as illustrated by the graph on page 3.
