14 aspects to consider in equipment selection Consulting

Apr 18, 2016· In selection, engineers must find the least expensive equipment that will be cool and quiet enough; but once satisfied, every additional dollar for extra cooling or added quiet is a luxury. However, additional benefits in efficiency and low maintenance, even at the expense of low cost, can be evaluated to find an ideal cost/benefit ratio.
