A simple analysis based on the linear model of energy savings indicates that the energy of the
MTSA process can be significantly reduced by right-sizing. For example, if it were possible to reduce
the size of the equipment from a volume big enough to handle 270 cards to a volume right-sized
for customer demand and operational flow (say 3 cards per day, five days a week), there would be
a staggering 99% reduction in energy required to satisfy customer demand for this process. While
this approach would probably require acquiring multiple smaller MTSA machines, or at least a more
flexible design to handle the variety of circuit cards tested in the equipment, the payoff in terms of
energy, estimated at around $51,200 annually, would be significant.
Other examples of equipment that were consistently well over-sized in terms of volume for current
demand at the facility (by 50% or more) were many of industrial ovens, including the vacuum ovens in
the Oil Room. While anecdotal evidence from the facility indicates that management and operators
are aware of and currently addressing this problem, for example by purchasing several smaller ovens
to replace one large shared oven, the full extent for energy savings from applying this principle to
equipment throughout the facility is well worthy of further focused re...
