Fans

Centrifugal fans are most commonly used for industrial air handling and HVACapplications. All centrifugal fans operate according to laws related to performancevariables, as follows:
• Airflow varies in proportion to fan speed.
• Total differential pressure is proportional to the square of fan speed.
• Power requirement is proportional to the cube of fan speed.
The fan laws show that changes in airflow and resistance to airflow can significantlyaffect the amount of power required by the fan.This highlights the importance ofducting that does not restrict airflow.Energy consumption by fans is influenced by many other variables, some ofthem related to operating and maintenance tasks. Other factors that affect energyuse by fans are related to the air-conveying system in which the fan is installed.

Our group can serve the following activities:

1. Streamline duct connections for fan air entry and discharge to reduce losses.
2. Optimize or reduce fan speed to suit optimum system airflow.
3. Control the local ventilation systemsto save the operating costs.
4. Measures taken to reduce electricity consumption by fans and pumps help reduce emissions from thermo-electricity-generating stations
