Energy Savings

The Universal AutoDual ® is so effective it typically allows end users to recover the capital outlay of their entire compressor purchase within 3 years in energy savings alone. Here's how we do it:

Example:  A savings analysis of a 25 HP, 2 stage, reciprocating or rotary screw compressor operating a factory that is producing 7 days per week on three shifts (8760 hours per year). 

Basis

25 HP = 23 KW x motor P.F. of 1.15 (power factor) = 26.45 KW

Unloaded KW = Full Load KW  (26.45KW) x

Unloaded KW (25%) x losses (part load motor efficiency

& power factor = 35% efficiency loss

Unloaded KW = 26.45 x 25 = 10.17KW 

     .65

1st Shift: 75% Loaded, 25% Unloaded

2nd Shift: 40% Loaded, 60% Unloaded

3rd Shift: 20% Loaded, 80% Unloaded

Electric Rate:  $.10/KWH

Unloaded kW: 25% of Full Load = 10.17KW at

8760 hours per year

Unloaded kW Savings

1st Shift:  2920 hours x .25 x 10.17 x .10 = $743

2nd Shift: 2920 hours x .60 x 10.17 x .10 = $1782

3rd Shift:  2920 hours x .80 x  10.17 x .10 = $2375 Total Annual Power Savings:  $4900**

**In areas of higher KWH rates, such as Metro New York, at 0.15/KWH, the annual savings would be  $ 7350.00/yr

Total Annual Electric Energy Savings = 49,000 KwHrs/year 

**In areas of higher KWH rates, such as Metro New York, at 0.15/KWH, the annual savings would be $7350.00/yr.
