The ecoPOWER® can operate in either natural or power mode alone or in both simultaneously.
The natural ventilation mode functions through two processes.
The first allows hot air to escape as a result of ‘stack effect’ buoyancy pressure. Hot air in the building rises and is released through the vent to be replaced by cooler ambient air.
The second process results from the ambient wind driving the turbine, thereby creating flow through centrifugal suction.
However they lack reliability due to their dependence on favourable environmental conditions. Natural ventilation also has performance limitations; e.g. cannot increase ventilation rates to meet peak or specific needs. To overcome these limitations, the ecoPOWER® can switch to efficient power mode, which allows natural flow rates to be boosted by powering the Electronic Commutating (EC) motor to drive the impeller.
This provides on demand response to boost flow rates during periods of low wind speed or special ventilation needs. In power mode, ecoPOWER® has a flow rate 3 – 5 times greater than the equivalent size natural ventilator operating at average city wind speeds.
What makes the ecoPOWER® revolutionary is its patented design. The ecoPOWER® design allows the wind turbine itself to be used as a centrifugal impeller, no separate fan is required when running in powered mode. The motor is installed in a direct drive configuration to the turbine, ensuring minimum flow obstruction for maximum air movement. It also results in lower maintenance costs.
The bearing system of the motor functions as the bearing system of the ventilator. This means that the vent can be free spinning under wind load, or power activated as conditions require.
The motor can be activated on by a simple manual switch or operation can be controlled by any digital measure, such as temperature, humidity, gas concentration level etc.
