Forbes and Company are the leading manufacturer of precision products in 4 segments - cutting tools, turnkey solutions for marking and traceability, industrial automation, and spring lock washers.
Since the machines are running 24 hours a day. The workers feel uncomfortable as the machine is constantly running.
Industrial fans installed there do not give enough air, and the sound of that fans is too high.
The problem in the shop is related to air movement. Also, the temperature in the shop is very high in summer.
Due to this shopkeepers can't work properly. Also, heat-related issues can be detrimental to employees
- Epoch 2.0, 18-ft Fan was installed with the following specifications ;
- Motor: Epoch 2.0;
- Coverage Area: 15000 Sq. Ft. (1393 Sq. m);
- Speed: 75 RPM;
- Peak Power: 1.1kW/1.5 hp;
Epoch 2.0, 18 ft diameter fan 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: 126 ft X 89 ft = 11,214 Sq. ft.
- Floor to Ceiling Distance: 25 to 28 ft,
- By a rule of thumb distance/1.5 gives us the approximate fan diameter.
- In this case, we chose to go with a 18-ft fan.
Fans and coverage area
Three test reports are collected for each fan installation as follows:
Power Consumption Report
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 35, 45, 55, 65 and 75 RPM. Power drawn at those speeds are 310, 490, 570, 785, and 980 W 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.
Input Current Report
The input current is also measured at 35, 45, 55, 65 and 75 RPM. Input current is recorded as 0.62, 1.3, 2.38, 3.85, and 4.8 A respectively. The input voltage varied from 230 to 240V during the measurement.
Air Flow Report.
The airflow is measured from the center of the fan and is recorded at every 3-ft distance. Values were recorded upto 27-ft from the center of the fan. The values were respectively, 230, 268, 340, 395, 414, 430, 410, 360, and 310 ft/min at distances of 3,6,9,12,15,18,21, 24, and 27-ft respectively.
