Absorption Chiller Service Guide | Nitrogen Gas Purging

Absorption chillers must maintain an internal vacuum condition to achieve proper cooling performance. If non-condensable gases, such as charged nitrogen gas used during storage or maintenance, are not properly removed, they can cause reduced equipment performance and unstable operation. This video briefly introduces the basic principles and procedures for purging nitrogen gas from an absorption chiller, along with key precautions to consider during on-site work. Depending on the manufacturer’s design, purge method, operating conditions, and site environment, the gas removal procedure and work process may vary. Improper purging may result in vacuum loss, reduced equipment performance, or equipment damage. This video is provided for general reference purposes only. For accurate work procedures, safety standards, or technical support suitable for your equipment, please contact a professional absorption chiller service company or your equipment supplier.
