A new range of fans that employs intelligent-motor driven impellers permitting units to be optimised for specific applications with regard to efficiency, speed, acoustic performance and cost.
The intelligent motors combine permanent magnet motor technology with integrated electronic controls. This combination allows units to be set up to meet specific performance requirements and respond to feedback from such devices as heat, pressure and humidity sensors to adjust air flow as required. The integrated package is also simpler to install and requires less space than conventional motor/drive alternatives.
Performance figures:
Flow rates up to 1400M³/Hr (825CFM)
Pressures up to 933Pa (3.5In.Swg)
Other features:
Motor power from 40W to 520W. EC (electronically commutated) motors, IP44 with CE, UL, CSA approval. Speed monitor output, integrated speed control via PWM or 0-10v signal.
Fans are not limited to the synchronous supply of the electricity 50Hz(Europe) or 60Hz(USA) so they can operate at much higher performances.
Onboard electronics are easily adapted to incorporate simple to use integrated speed control.
Fans can take a PWM signal or a 0-10V DC signal for speed control. No need for bulky controllers which allows for easy installation, no hard wiring and no extra controller costs.
Speed control is very efficient and quiet - almost silent running at low speeds
Fans retain their efficiency throughout the speed cycle making a product that runs cooler and uses less energy.
QBL EC fans include onboard rectification of the supply voltage giving a huge advantage for people supplying product over the world. Whether the voltage is between 200v -277v AC 1~ 50 or 60Hz the performance will be exactly the same. This also applies to 3 phase fans when applicable 380-480v 50/60Hz giving stable predictable performance anywhere in the world.
Fans are generally more efficient and run cooler than their single phase counterparts, giving a much lower energy consumption cost for long term operation.
Fans also have a ‘Hall effect’ signal output giving end users the chance to monitor the fan speed performance via a simple sensor – giving early warning of a system failure or for remote monitoring
On bigger versions of the QBL EC range, fans may be connected to a computer or BMS system via a RS232 interface. This enables real-time on demand access to the fan performance locally or further a field.
