Save Energy & Money With Controls From Enigin

Engineering seems to be a fairly stable industry, stable in the sense that apart from the leading edge of engineering research, many engineers follow sound, tried and tested disciplines and processes.

At times it is difficult to break down established barriers, but that can be a good thing as the engineers want to be certain of a new process or method before implementing it, they do like to measure twice and cut once.

Commerce, industry and the public need to realise that some of the greatest energy savings to be made are through engineering and engineering processors.

Jeff Whiting, energy spokesman for Mitsubishi Electric’s Energy Centre, has written an article for Control Engineering themed “Using Machine Controls for Energy Engineering.”

It underlines how automated controls are a very good solution to producing substantial energy savings – as he states:

“When designing a machine engineers primarily think functionally: what are we making, how can we do that, what processes are involved?

“Energy considerations, where they are considered, usually come somewhere low down the list of goals.”

This has been the norm in engineering hence the need for retrofitted controls for many applications, as Whiting said energy saving controls or solutions were not considered when a piece of equipment was designed.

But is it not more expensive to add controls post production? Yes, it is bound to be, but applications such as Enigin’s iMec, ACES, LESS and CUES are all automated and will save so much money that the investment to retrofit is a no-brainer.

Whiting highlights this very fact:

“Extra equipment needed often pays back in energy saving in just a few months. Given that the life expectancy of automation equipment is over 12 years, substantial returns during the life of the machine can be expected.”

He also realises there is a business opportunity for those who can supply retrofit energy saving control equipment, when he says there is a “window of opportunity” which provides “a competitive edge” as energy concerns and carbon emission consciousness increases.

What sort of payback can be expected, Whiting makes an estimate:

“Let’s quantify savings we could reasonably expect. Many public buildings have been retrofitted with Building Management Systems in recent years: a comprehensive study of their performance suggests that this leads to an average reduction in annual energy bills of around 15-20 per cent.

“In energy hungry industrial processes, a 20 percent energy saving could be very significant to the overall bottom line of the entire business.

“It is reasonable to take this as a rule of thumb and say a plant or machine designed for energy efficiency will be one-fifth cheaper to own and run.”

Whiting estimates 20 percent saving, a substantial amount and experience shows that in many applications the savings are far greater.

Also to be considered is the increased life of the plant that is intelligently and automatically controlled, as the process often extends the life of the equipment considerably, due to lower running times and running under lower stress levels.
