Drain Vessels
Classic Filters are always looking for solutions to common problems. A drain vessel is designed to increase the volume of a coalescing filter housing to hold more liquid and increase the service time. This is especially useful for negative-pressure applications. In these cases, an automatic float drain cannot be used.
Fits to the Drain Port of a Coalescing Housing
Drain vessels can either be attached directly to the drain port of a housing. In effect, this extends the bowl of the housing to allow far more liquid to be held before the coalescing element is flooded. Alternatively, they can be attached by means of a valve with a valve on the drain end. In this arrangement, the liquid can be drained into the drain vessel and then the drain vessel emptied later.
Typically these housing are specified for coalescing systems in Hydrogen electrolyser systems. In these systems, liquid is being removed from the H2 and O2 gases.
Need Something Special?
As well as our standard range of drain vessels we build a large number of special ones. In fact, we have even produced them to be used as storage vessels with specific volumes and sampling cylinders.
