I have seen many pictures on the net with the Displacement lubricator mounted on the side of the steam chest. Does this position work. I thought the idea was to have it in the steam supply pipe so the passing of the steam drags some of the oil with it. Thanks Garry

It's not really dragged out by the steam. The cooler lubricator will collect condensation that settles to the bottom and the lighter oil then flows out into the chest or pipe
