1 .Eaton Power Quality, India A Case Study : Epoch 2.0 HVLS 12-ft Fan

Achieve 180% savings on electricity while getting 2x the airflow, all with the world's lowest sound level at under 35 dBA

This industrial installation in India features the Epoch 12-ft 5-blade HVLS fan, operating at 130 RPM and powered by the advanced Epoch 2.0 motor and controller system. The solution utilizes a direct drive PMSM motor with active power factor correction, achieving the lowest weight in its class while delivering 90Nm of torque with 1.1kW (1.5 hp) power output.

Problem

  1. Eaton power Quality is home of UPS, power suppression and production, and power management products. The plant is located at Pondicherry.
  2. In summer days, temperature in shop makes employees highly discomfort. Also due to atmospheric temperature machineries get overheated, so the person working on machine unable to work.
  3. The plant shop lacked proper ventilation, so the air movement is not appropriate.
  4. To get air movement in proper way, the management decided to install HVLS fans in the shop so that, the air ventilation in the shop becomes better. So that person working in the shop becomes comfortable.

Solution

  • Epoch 2.0, 12-ft 14 Fans was installed with the following specifications ;
  • Motor: Epoch 2.0;
  • Coverage Area: 7,000 Sq. Ft. (650 Sq. m);
  • Speed: 130 RPM;
  • Peak Power: 1.1 kW/1.5 hp;
  • Epoch 2.0, 12 ft fans are 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: 90 Ft X 62 Ft = 5,580‬ Sq. Ft.
  • Floor to Ceiling Distance: 14 to 16 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.

Test Reports
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 90, 100, 110, 120 and 130 RPM. Power drawn at those speeds are 400, 500, 690, 810, 990 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 90, 100, 110, 120 and 130 RPM. Input current is recorded as 1.6, 2.2, 3, 3.8, and 4.3A 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 24-ft from the center of the fan. The values were respectively, 190, 330, 460, 433, 410, 354, 310, and 290 ft/min at distances of 3,6,9,12,15,18,21, and 24-ft respectively.

Include any additional information that helps users understand the application better.

2. BIC Cello India Pvt Ltd, Gujarat, India

Achieve 155% savings on electricity while getting 2x the airflow, all with the world's lowest sound level.

This industrial installation in India features the Epoch 24-ft 5-blade HVLS fan, operating at 62 RPM and powered by the advanced Epoch 3.0 motor and controller system. The solution utilizes a direct drive PMSM motor with active power factor correction, achieving the lowest weight in its class while delivering 170Nm of torque with 1.5kW (2.0 hp) power output.

Problem

  1. BIC cello is manufacturer of writing instruments and they have more working people in the assembly area and retails store area.
  2. There is no air movement as more workers work so the temperature rises, so the workers working in this area did not feels comfortable.
  3. Due to such working atmosphere, productivity of the employees reduces, which affects industry’s growth.
  4. As the air comfort is very important factor, branch head tried to make area air comfortable so that workers working in that area work with better efficiency.

Solution

  • Epoch 3.0, 24-ft 05 Fans were installed with the following specifications ;
  • Motor: Epoch 3.0;
  • Coverage Area: 30,000 Sq. Ft. (2,787 Sq. m);
  • Speed: 62 RPM;
  • Peak Power: 1.5 kW/2 hp;
  • Epoch 3.0, 24 ft fans are 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: 393 Ft X 98 Ft = 38,514‬ Sq. ft.
  • Floor to Ceiling Distance: 35 to 40 ft,
  • By a rule of thumb distance/1.5 gives us the approximate fan diameter.
  • In this case, we chose to go with a 24-ft fan.

Test Reports

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 12, 23, 32, 42, 52 and 62 RPM. Power drawn at those speeds are 81, 118, 188, 390, 720, 1152 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.

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 24-ft from the center of the fan. The values were respectively, 275, 295, 334, 411, 492, 413, 393, and 334 ft/min at distances of 3,6,9,12,15,18,21, and 24-ft respectively.

Input Current Report

The input current is also measured at 12, 23, 32, 42, 52 and 62 RPM. Input current is recorded as 0.404, 0.57, 0.92, 1.93, 3.15, and 5.11 A respectively. The input voltage varied from 230 to 240V during the measurement.
