In low-pressure chillers, what is the critical factor in selecting a ruptured disc?

The critical factor in selecting a ruptured disc for low-pressure chillers is the pressure rating. Ruptured discs are safety devices designed to protect equipment from overpressure conditions by opening at a predetermined pressure level. In low-pressure systems, it is essential that the ruptured disc is rated for the specific pressure range of the system to ensure proper functioning and prevent potential failures or safety hazards.

A pressure rating that matches or exceeds the operating pressure of the low-pressure chiller is crucial for safety. If the pressure rating is too low, the disc may fail too early, leading to loss of refrigerant and possible damage to the system. Conversely, if the rating is too high, it may not provide the intended safety margin.

Understanding the importance of pressure rating in the context of safe operation and regulatory compliance helps in selecting the proper ruptured disc for effective protection of low-pressure refrigeration systems.
