This development course is available in both virtual and in-person, instructor-led formats, it is a two-day chill water systems course that will develop your team how to keep them running efficiently, whether it keeps people or equipment cool.

Description:
Team members will learn about components used in chilled water systems, uses and applications of chilled water systems among many other things. This workshop is perfect for anyone looking to increase their knowledge about chillers, cooling towers and other chilled water systems.

Course Outline:
Day One – Topic

Day One examines the basics of chilled water systems including chillers and cooling towers. We’ll do an overview and review heat theories, so team members understand why things happen.
