What is the relief pressure of Anhydrous Ammonia?

The relief pressure of anhydrous ammonia is typically set at around 150 PSIG. This value is established to ensure that the pressure within the refrigeration system does not exceed safe operating limits and to prevent potential system failures or leaks. In industrial refrigeration systems, proper relief pressures are critical for the safety of the equipment and personnel, as too high of a pressure can lead to dangerous situations.

Setting the relief pressure at this level allows for a safe buffer in the operational pressure range while providing adequate protection against pressure build-up due to thermal expansions or equipment malfunctions. Understanding the typical relief pressures for refrigerants like anhydrous ammonia is crucial for operators, as it informs decision-making regarding system safety, maintenance, and compliance with safety regulations. Furthermore, the value of 150 PSIG aligns with industry standards and safety guidelines established for ammonia refrigeration systems.
