size: 315 - 710 mm (impeller diameter) highly efficient EC technology backward curved impellers integrated control system (EC controller) speed is 100% infinitely variable no condensate formation due to 2-chamber aluminium profile discharge in any direction possible extremely low noise The housing consists of a frame made of an extruded aluminium profile with 2 chambers and plastic edges, as well as double-skinned, 20 mm thick panels made of galvanised steel sheet metal with insulation made of non-combustible, sound and heat-insulated glass wool mats. As standard, one casing wall is left open opposite the impeller. EC Unoboxes are suitable for outdoor installation with appropriate accessories. Backward curved high-performance impellers of aluminium are used. The impellers are mounted directly on the rotors of the external rotor motors and are dynamically balanced on two levels with the rotor according to quality level G 2,5 / G 6,3 as per DIN ISO 21940-11. The electrical connection for size 50 is done on the lead-out terminal box, from size 67 directly at the motor terminal space (cable routing provided). Integrated motor protection is indicated via an alarm relay. In the “open loop” (standard) model, the speed is continuously provided by a 0-10V signal or a potentiometer (accessory).
