He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - That purge units are required on low-pressure chillers because they operate in a vacuum, which causes leaks to draw air and moisture into the system. - Why non-condensable gases accumulate at the top of the condenser, where the purge unit is located to remove them. - That excessive or frequent purge unit operation is a critical exam indicator that the chiller has a leak and needs to be repaired. - How moisture contamination in a chiller leads to the formation of highly corrosive hydrochloric and hydrofluoric acids. - The difference between older purge units that vented refrigerant and modern low-loss units designed to comply with EPA regulations.
