Client: Metropolitan municipal wastewater treatment plant
Engine Service: Dual-fuel generators

​

ESi personnel completed an engine controls project for a major US municipality, updating an unreliable system that controlled four engine-generators. The plant had experienced several unplanned engine shutdowns caused by poor functioning of the control system. Because the controls were centralized, a single failure would cause all engines at the facility to shutdown, or fail to start.

​

The client requested decentralization to allow each engine to function independently. Upon evaluation, it was determined that the addition of a small PLC would eliminate many points of failure in the system.

​

In addition to refining the engine control design, ESi engineers worked closely with plant personnel to inspect and tune all of the on-engine mechanical components. Training was provided to ensure continued engine reliability.
