For very large plate heat exchangers with several hundred plates and high pressure units, using any type of manual wrench can be a difficult task. For these units and also PHE's that are opened frequently, you may want to consider our hydraulic closing system.
Our system uses four center hole cylinders, which are positioned at the corners of the moveable frame plate. The system is used to both open and close the heat exchanger. Each cylinder will deliver 60 tons of force with a total of three inches of travel, so your plate heat exchanger is opened or closed 3 inches at a time by the push of a button.
