Features and Constructions:
Rosenberg centrifugal fans of ranges E/DKHR and E/DKHM with free running impellers out of aluminum are very compact units. The fans have been optimally designed with regard to air movement. They combine a voltage controlled AC-external rotor motor and a newly designed high efficiency impeller.
The combination of voltage controlled Rosenberg- external rotor motors, flexible production of impellers and high end metal fabrication, gives Rosenberg the capability to manufacture fan modules that provide the best possible benefit to customers while taking the design demands and the customers application into consideration.
