In July 1991, a 65-ton electric chiller was in need of major repair at NutraSweet's R and D facility outside of Chicago. Instead of automatically repairing or replacing that chiller, NutraSweet engineers Larry Aubry and Gerald Schwartz began to look at other alternatives. What they discovered was that a natural gas absorption chiller was a cost-effective, environmentally safe alternative effective, environmentally safe alternative perfectly suited for their application. The benefits for NutraSweet are straightforward: energy bills have been cut by more than [dollar sign]70,000 annually, existing boiler capacity is better utilized, existing electrical cooling system life is extended, maintenance costs are reduced, and no-ozone-depleting CFCs are utilized by the natural gas chiller. Simple payback on the unit, originally expected to be almost four years, has been reduced to closer to three.
