Product Overview
This PLC control panel is built for parallel screw compressor racks with one to three screw compressors. It works with common screw compressor brands and is operated from a 7-inch industrial touchscreen that shows the live status of the rack. The same control logic used on the reciprocating panel is applied here, with the protection and alarm functions set up for screw machines.
Product Features
Compressor dead-band control is driven by suction pressure, so the rack adds and sheds compressors to hold the set pressure band. The panel reads the alarm signals from each compressor in real time, which helps with fault finding and after-sales support. Air-cooled, water-cooled and evaporative-cooled modes are available to suit the system design.
Structure
The panel is housed in a floor-standing metal cabinet. The front carries the touchscreen, three digital displays, the emergency stop and control buttons. The cabinet is wired and tested before delivery and can be configured to the compressor count and cooling mode of the rack.
