All condensers will foul, causing a combination of heat transfer and efficiency issues and other potential problems to different equipment within the plant. However, Air Cooled Condensers pose significant challenges that differ from the typical Steam Surface Condenser found in Power Plants.

This webinar will focus on the cleaning and leak problems that commonly occur on ACC units and how end users can minimize downtime and improve plant efficiency by maintaining the effectiveness of their ACC unit. We will discuss cleaning technologies, the effectiveness of the cleaning process, the time required to perform the task and the frequency these tasks need to occur. We will also examine leak detection and the methods used to find the troublesome leaks in the miles of piping in the ACC unit.

This webinar is geared toward the engineers and maintenance personnel that are new to ACC configurations, those that work with ACC units but have cleaning and leak issues right now and those plants that are considering or having an ACC unit built on site now or soon.

  • Discussion of Cleaning and Leak Detection
  • Cleaning technologies
  • Effectiveness of the cleaning process
  • Leak discovery methodology
  • Improvement of plant efficiency and time management
