New Ostberg fans
Now new models have been added to the already well-established fans:
• ducted fans CK EC;
• ducted fans in an insulated housing IRB EU for rectangular ducts;
• roof fans TKS EC.
Fans OSTBERG with the EU-engines have a number of advantages:
• Low power consumption. The high efficiency of the engine (90%), reducing operating costs by at least 30%
• Smooth and precise adjustment. Fan control is carried out by a control signal of 0-10 V. When the values of the control signal changes the fan speed, and delivers as much air as needed for the ventilation system
• Starting currents are minimized, since the built electronic control system when running the fan continuously brings the current value of the minimum values to the worker. This allows you to save on wiring and switching equipment
• Built-in protection against overheating of the motor and electronics, as well as protection for locked rotor
• Low level of noise in low speed mode
• High reliability and long service life due to the absence of sliding electrical contacts in the engine.
