A drain system that is connected directly to pressure vessels is called a “pressure” or “closed” drain system, throughout the chemical process industries (CPI), the need to drain a tank or process vessel arises. A drain system that collects liquids that spill on the ground is an atmospheric, gravity or open drain.

Drain tank vessels are designed and manufactured to increase the volume of a coalescing filter housing to hold more liquid and increase the service time. This is mostly useful for negative-pressure applications when automatic float system failed or cannot be used.

Drain vessels can either be attached directly to the drain port of a housing in effect extending the bowl of the housing to allow far more liquid to be held before the coalescing element is flooded, or they can be attached by means of a valve with a valve on the drain end so the liquid can be drained into the drain vessel and then the drain vessel emptied later.
