Air is your biggest enemy in any refrigeration system. If you have high purge minutes on your chiller it is very possible that you have substantial leaks on the machine that need to be located and repaired.

You can pull the entire charge, and pressurize the system with nitrogen, or you can use a pressurizer. in this video we walk you through the process of how to use a hyperwatt pressurizer to find leaks in a low pressure centrifugal chiller.
This video runs through how to use a HyperWatt chiller pressurizer to pressurize and leak check a low pressure Trane centrifugal chiller.

This is the process used to find vacuum leaks on the machine that bring air into the system during operation.

Trane CVHE and CVHF chillers were depicted in the video, but this process will work on York chillers, carrier chillers, and all other low pressure centrifugal chillers that operate in a vacuum



Wether your a project manager, mechanical engineer, or beginning your career as a chiller technician, this video walks you through the basics of how to pressurize a machine so you can grow in your career.
