When conducting leak testing on a low-pressure chiller, what is the maximum pressure that should be used?

The maximum pressure that should be used for leak testing on a low-pressure chiller is 10 psig. This limit is established to ensure safety and proper functioning of the chiller's components during testing. Operating above this pressure can potentially compromise the integrity of the system and could lead to unsafe conditions or equipment damage.

Low-pressure chillers are designed to function optimally at specific pressure ranges, and exceeding the maximum pressure can stress seals and connections, creating further leaks or failures. Conducting leak tests at 10 psig helps ensure that the chiller can be safely tested without exceeding the thresholds it is built to handle. It is important to adhere to these guidelines not only to maintain system efficiency but also to comply with regulatory standards and best practices in HVAC system maintenance.
