A key component of sustainability policy is a reduction in energy use. Fortunately, implementing new air quality measures can lead to such a reduction. For example, RoboVent’s dust collectors are designed to use less energy. RoboVent’s electric motors are energy efficient, and our ePad Control Panel helps monitor equipment and make energy-saving adjustments as needed. The AutoSaver feature allows your system to rest when welders are idle but turns it back on when the welder strikes an arc, avoiding unnecessary energy use. Working with RoboVent’s industry-leading engineers to improve your air quality can lead to significant energy savings. These benefits are, of course, in addition to the many other benefits that come from cleaner air.
Energy savings can derive from cleaner air in other ways, as well. Putting your dust collectors into a networked array can create new efficiencies. For example, RoboVent’s Grid Configuration connects your dust collectors into a system that needs only 70% of the airflow that the individual units need. Over time, this configuration saves significant amounts of energy and money. Another RoboVent product designed to save energy is the eDrive Automatic VFD. The eDrive monitors airflow and automatically adjusts the motor RPM to compensate for filter loading. Energy peaks and valleys are evened out, and energy use is cut by around 40%. As with any sustainability option, a company must weigh the return on investment (ROI). The ROI on the eDrive varies from 8 to 14 months, depending on energy costs.
One of the fastest ways to save energy and meet sustainability goals is to end the practice of venting contaminated air to the outside. A comprehensive dust collection system will filter your air and return clean air back to your facility. This avoids the need for make-up air and to spend money heating or cooling that air. If you are venting to the outside in winter, your warm air gets exhausted along with your contaminants. Fresh air brought in from the outside needs to be heated. Likewise, in the summer your air-conditioned air gets vented out with the contaminants, forcing you to cool the make-up air. Both of these practices add significantly to your utility bill.
