What additional feature should vapor recovery receivers include?

The inclusion of a minimum rated pressure in vapor recovery receivers is crucial in maintaining the efficiency and safety of the vapor recovery system. This feature ensures that the system operates within specific pressure parameters, promoting optimal vapor recovery and preventing potential issues like over-pressurization or inadequate vapor collection.

Having a minimum rated pressure helps in assuring that the vapor recovery system functions properly, reducing the risk of leaks or suboptimal recovery rates. It provides a baseline for the system's operation, ensuring that the pressure remains above a certain threshold to effectively recover vapors before they can escape into the atmosphere, which is important for both environmental and safety regulations.

While features like automatic shutoff, pressure gauges, and cooling mechanisms have their own importance in safety and functionality, the minimum rated pressure specifically addresses operational standards that are critical for the effective recovery of vapors and maintaining compliance with industry regulations.
