Utility Boiler Engineering Capabilities

The condition and successful function of utility boilers is crucial to any industry that utilizes them for heat or power. Regular maintenance, inspections, assessments, and prompt action to address any issues can help ensure normal operations and prevent costly downtime for repairs.

Pearl Engineering started 20 years ago in the Utility Boiler driven power industry and our dedicated and experienced engineering staff has decades of experience working for the major boiler OEMs and for owner/operators maintaining and operating all styles of utility boilers.

Whether it is designing a new system, managing your replacement project, or inspecting your equipment and offering the best repair solutions, Pearl Engineering is committed to only providing good value to our clients at lower costs and with greater consistency.

Because our office’s are centrally located in Wisconsin, our associates eliminate the need for large expenses and travel time associated with airline travel, such as overnight layovers, flight delays, hotels, and meals, that many other firms will ultimately account for in their invoice. Your local Pearl Engineering team is able to drive straight to your site to do the work without the hassle of rescheduling or re-booking a flight if there is an outage delay or extension. Depending on your location, we may not even face any travel or overnight costs.

The advantage Pearl Engineering has as a local Wisconsin engineering firm is that the engineers and inspectors you will interact with will be the same every time your plant calls on Pearl Engineering to perform boiler inspections, evaluations, and upgrades for years to come. The familiarity with your plant means our future work can be completed quickly, thoroughly, completely, and prevent the need for overmanaging by your team.

Pearl Engineering has the engineering expertise and experience to address any utility boiler problems, issues, or maintenance; and if not we have the integrity to say so and the resources to refer the client to someone who can.
