BACKGROUND

Induspec was invited into a large local manufacturing facility in order to perform an overview energy audit. Induspec observed some specific conditions, quantified them and put together business cases for correcting the observed inefficiencies.

INITIAL CONDITION

One of the biggest observed inefficiencies was a plant wide cooling water system. The system was significantly oversized for current needs and the excessive water flow overcapacity resulted in throttling valves operating at near closed positions. It was soon clear that the oversized pumps not only consumed a lot of energy, but were operating at such a poor efficiency point that they actually contributed significantly to the water warming.

ANALYSIS

Induspec proposed changes to four pumps and a drastic change to the 6” and 8” piping system. In addition, the client identified that the existing water cooling tower was well past its useful life so that a new cooling tower and storage tank were added to the project scope.

SCOPE

Induspec performed the initial energy quantification and performed design calculations for new pumps, complete with variable speed drives. Induspec designed a significant structure, complete with foundations and a jib mount, to hold the new water cooling tower and water storage tank. Finally, Induspec supervised all construction, commissioned the system with the client, procured energy savings rebates with the energy provided, and provided as built drawings.

RESULTS

Not only did Induspec install a robust new cooling system, but the client saved tens of thousands of dollars in annual energy costs making for a quick ROI on this project. The system was tuned and was fully commissioned within only a few hours.
