What is the maximum safe pressure for testing the low side of an ammonia system?

The maximum safe pressure for testing the low side of an ammonia system is 150 psi. This standard is established to ensure the safety of personnel and equipment. Testing at or below this pressure allows for sufficient verification of the system's integrity without exceeding the designed pressure limits, which mitigates the risk of leaks or failures.

Ammonia systems operate under specific design parameters, and exceeding these values can result in dangerous situations, including potential explosive decompression or release of hazardous substances. Therefore, adhering to the recommended 150 psi for low side testing is crucial for maintaining safety standards in the operation and maintenance of ammonia systems.
