When a machine is not immediately productive, the ECOGATE system closes the duct that connects the machine to the dust collector. Typically that is between 30% and 60% of machinery at any given time. If you reduce the volume of vacuumed air by half, your motor uses only 12% of your previous energy consumption (78% savings) to take your dust to the dust collector with the proper velocity and suction. The claim of 49% to 78% energy savings is supported by laws of physics that apply to ventilators.

 
 

The following example shows workstations in use (WS#1 to WS#7) and consequent CFM (air volume) demand from an actual factory. 0 indicates that the machine is OFF, and 1 indicates that the machine is ON. The following is a 30 minute sampling (from 1:00 PM to 1:30 PM) from one week's data collection. Data is based on data loggers installed by SC EDISON on the woodworking machines. The factory considers themselves to be at 100% production mode during this period, however, data loggers monitored the actual on/off activity of the saw blade.

Below is a graphic illustration of the CFM requirements identified above. These data are typical of most factories (low percentage of use of the workstation).

Total air volume demand (0 to 22.000 CFM) based on above table


The average air volume demand of this factory is actually 10,666 CFM. Peak air volume demand is 21,292 CFM. The air volume demand should all machines hypothetically be working at the same time is 25,415 CFM. Classic "unregulated" designs take this hypothetical demand and add at least a 20% safety margin. In this instance the factory's cyclone motors and dust system were designed to maintain a constant airflow of 30,498 CFM (25415 CFM + 20%).

 

HP (horse power) demand based on above data

HP1 (green) is HP demand without the ECOGATE System

HP2 (blue) is HP demand with the ECOGATE System

The BLUE line indicates the power (in Horsepower) requirements of an "unregulated" design while the RED curve demonstrates potential power requirements if only actual CFM requirements are satisfied.


Based upon the laws of physics, here is how you save.
