Data logging is key to real compressed air energy savings 12 October 2010

Data logging is one of the keys to getting real energy savings from compressed air plant, according to rotary vane compressor manufacturer Mattei.

Mattei general manager Andy Jones believes that many plants are operating with inefficient or unsuitable compressors, and says that data logging can help sort the wheat from the chaff.

"Data logging is the best way to identify whether changes to the system or investment in new equipment can result in energy savings," says Jones. "This is why Mattei always recommends them to any customers who are planning to upgrade or change their systems – so they can be confident they are doing the right thing."

And he adds: "We have seen a number of cases where data logging can result in significant energy and financial savings. Recently, one customer saw an annual saving of £26,000, following a data logging exercise which identified that two compressors installed could be replaced with new more efficient machines, with a payback of just two years."

Jones also makes the point that, in some cases, data logging reveals inappropriate compressor replacement projects, which means "the customer doesn't spend money unnecessarily".

And he indicates that the process also identifies variable speed compressors might have a place, because of their ability to save energy where there are peaks and troughs in air demand.

"We often hear that companies feel they can't afford to replace a compressor but, with the potential for very high savings, we believe businesses should consider the long-term. Perhaps they can't really afford not to change them," comments Jones.
