A Case Study : Epoch HVLS 12-ft Fan By Falco eMotors Inc.
Report No. 030420-01
Problem:
- Stauff India Pvt Ltd is the manufacturer and supplier of pipework equipment and hydraulic components.
-
The shop shed is made of steel structure, so the shop is hot and humid in summer temperatures.
-
In such situation, employees have to deal with heat related issues like heat stroke, heat exhaustion and heat stress.
-
Employees are not comfortable working in such situations and they are prone to illness and health problems.
- To facilitate the work environment, Staff India decided to install an HVLS fan in the shop.
Solution:
- Epoch 2.0, 12-ft 02 Fans 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.
Site Survey:
A site survey is mandatory before any HVLS fan recommendation. The survey revealed the following dimensions:
- Total Area: 157.5 ft X 55.8 ft = 8,788 Sq. ft.
- Floor to Ceiling Distance: 18 to 20 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:
Test Reports:
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 90, 100, 110, 120, and 130 RPM. Power drawn at those speeds are 410, 530, 680, 820 and 980W 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 90, 100, 110, 120, and 130 RPM. Input current is recorded as 1.9, 2.2, 2.8, 3.6 and 4.2A 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, 290, 358, 433, 460, 420, 410, 354, 330, 290, 250 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 14-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 $1,184 to $3,894 per year over any competitive brands because of its unique technology.
