Johnson Controls P72AA-18 Differential Ammonia Pressure Control 12" -50 PSI DPST

The Johnson Controls P72AA-18 Differential Ammonia Pressure Control is an essential control device in industrial HVAC systems, that is used to control pressure differentials in ammonia refrigeration systems. It works through pressure variations within its 13" bulb and 36" capillary tube and then regulates the settings for proper functioning and safety. It comes with a threaded 0.5” connection and has a solid construction it has a pressure range of up to 80 PSI and the flow rate is regulated linearly for stability. This control improves system performance by avoiding pressure changes and thus increases equipment’s duration and decreases energy use. This makes it reliable in maintaining constant pressure which in turn ensures that HVAC equipment runs smoothly without breakdowns.
