A SMART product - K3G Series
Why is this product “smart”?
Intelligent airflow is possible using the ebm-papst K3G centrifugal fan series. This series uses a programmable EC external rotor motor with an internal P-I process controller. Constant airflow over changing system pressure can be obtained by using a differential pressure sensor to measure the pressure change across the fan inlet nozzle and feeding this data to the process controller. Once the desired operating point and differential pressure sensor characteristics are entered into the fan EEPROM, the fan speed will react to changes in nozzle pressure to maintain a constant airflow.
Why is this “smart” product innovative and/or different from other products on the market?
- the process controller, variable speed drive, electrical filtering and overload protection is all included
- low noise and vibration across the entire fan speed range
- 0-10v output signal to indicate motor loading
- adjustable speed drive and motor are fully compatible – no burnt out windings from corona effect and no arcing in the bearings
How does this product benefit the contractor and the end user?
- 100% speed controllable without needing to install added components like VFD's and associated filters
- Both 0-10 VDC and 4-20mA output signal accepted from a differential pressure sensor
- Power supply for differential pressure sensor is built into motor – external DC power supply not needed
- “set & forget” airflow
- Steady performance over the full voltage range (3-phase, 380-480VAC, 50/60Hz)
- Modular and compact design makes installation and removal easy, only dealing with a single part
- Direct drive, no belts, maintenance free ball bearings
- Wide size and performance range to choose from (12-25 inch) impeller diameter, 1-3 kW, 2750-9500 CFM)
