Chillers: Operations and Maintenance
Description
Become a pro at chiller maintenance. This 3-day hands-on course delivers a solid understanding of water cooling systems and how to maintain them for maximum efficiency. You’ll discover how chillers work and what causes common problems. You’ll learn about the latest technologies for keeping systems at their peak performance. Plus, you’ll develop practical skills in the hands-on lab to gain direct experience with chiller operations and measurements.
NTT is a proctor for the 608, 410A and Test of Excellence. Chillers testing starts at 3pm on Thursday of the course week. Upon registering for this class, you can request a FREE copy of the EPA Certification Exam Preparatory Manual. This manual is for participants taking the ESCO 608 exam offered in these classes.
