A Case Study : Epoch HVLS 12-ft Fan By Falco eMotors Inc.
Report No. 030820-02
Electrolab India Pvt. Ltd. is a manufacturer of Pharmaceutical testing equipment and peristaltic pumps.
In the cafeteria in Electrolab, their workers and office staff are dining in the lunchtime, and as industry is located in Mumbai, the main issue is related to the humid and hot climate.
In the canteen area of the industry, low air ventilation and heat exhaustion make employees feel uncomfortable.
The company has decided to install an industrial HVLS fan that can provide some relief in this case.
- Epoch 2.0, 12-ft Fan was installed with the following specifications ;
- Motor: Epoch 2.0;
- Coverage Area: 7000 Sq. Ft. (650 Sq. m);
- Speed: 130 RPM;
- Peak Power: 1.1kW/1.5 hp;
Epoch HVLS fans becomes most popular with amazing airflow and airflow efficiency.
A site survey is mandatory before any HVLS fan recommendation. The survey revealed the following dimensions:
- Total Area: 75 ft X 34 ft = 2,550 Sq. ft.
- Floor to Ceiling Distance: 15 to 17 ft
- By a rule of thumb distance/1.5 gives us the approximate fan diameter.
- In this case, we chose to go with a 12-ft fan.
Fan and Coverage Area:
Three test reports are collected for each fan installation as follows:
- Power Consumption Report;
- Input Current Report;
- Air Flow Report.
Those reports are shown for this site:
Power consumption report captures the real as well as apparent power. Epoch HVLS fans are the only fans in the world to have active power factor correction and unity power factor. Therefore the Watts (Real Power) and VARs (the apparent power) are almost the same. The power has been captured at 80, 90, 100, 110, 120, and 130 RPM. Power drawn at those speeds are 651, 658, 708, 818, 857, and 935W respectively. The chart above also shows trend lines generated using Excel for real and apparent power to take into account any measurement errors as fan power consumption can be modeled by well known equations.
The input current is also measured at 80, 90, 100, 110, 120, and 130 RPM. Input current is recorded as 2.9, 3, 3.2, 3.6, 3.8 and 4.02A respectively. The input voltage varied from 230 to 244V during the measurement.
The airflow is measured from the center of the fan and is recorded at every 3-ft distance. Values were recorded upto 30-ft from the center of the fan. The values were respectively, 295, 358, 433, 460, 422, 410, 354, 330, 295, 260 ft/min at distances of 3,6,9,12,15,18,21,24,27 and 30-ft respectively.
Estimated Yearly Savings while Using Epoch HVLS Fans
Epoch 12-ft fan was compared against Indian HVLS fan Manufacturer. Based on their data sheet, daily, monthly and yearly power consumption and costs were calculated. An Epoch HVLS fan will save the end user anywhere from $204 to $1,457 per year over any competitive brands because of its unique technology.
Above is the picture of the finished installation.
