Panel Systems (Gas Compression)

FW Murphy offers a full line of control panels that interface with a wide range of engine, motor, pump and compressor applications. Murphy believes that you start with a basic control platform, then customize your panel with instrumentation, layout, and software until you get it exactly how you want it.

Whether you need a fully configurable fault annunciator and shut-down system, auto-start and basic engine control, or full-time data logging and expandable communication capabilities, you'll be given the total FW Murphy treatment — reliable control backed by full customer service.


Vapor Recovery Unit Controller Panels


The VRU Pro™ Controller Panels are designed specifically for tank battery vapor recovery compressors. This full-featured vapor recovery controller can be panel mounted as a stand-alone application or integrated with an EICS® or AFR-1/AFR-9/AFR-64 package.

The controller keeps the compressor in a ready-to-start condition until tank pressure reaches a preset level. At that point, it starts the compressor to recover the vapors and draws pressure back down to the set point. It then turns off the compressor.

It pairs with single stage reciprocating, screw or scroll compressors and is certified for CSA Class I, Division 2 hazardous-area operations.

•   Comprehensive signal monitoring and control
•   Automatic start and stop based on suction pressure
•   Engine / electric motor monitoring and protection features are selectable
•   Setup configurable through keypad
•   Equipped with 18 fit-for-purpose fixed digital, analog, thermocouple and frequency inputs and nine (9) field-effect transistor (FET) and analog outputs
•   Modbus RTU monitoring and remote control ready (RS-485)
