CEO Two Plunger-Lift Controller Overview

eP's CEO Two plunger-lift controller is designed to provide automatic high/low-pressure shutdown with optional reset. The CEO Two controller accepts analog as well as digital input, including data sent from Murphy switches, float switches and other types of sensors. This versatile controller can operate in three different modes: time-based, single-valve and double-valve.

Applications of the CEO Two-Plunger Lift Controller

  • CEO Two Plunger Lift Controller Simple plunger-lift operations
  • High/low shutdowns
  • Conventional intermitting (stop-cocking)
  • Wells just beginning to liquid load
  • Sour-gas applications (with remote solenoid)

CEO Two Plunger-Lift Controller Features, Advantages, & Benefits

  • Simple controls and settings allow for easy configuration, minimizing operator error.
  • Optional solar panel extends battery life during daylight hours, reducing operating costs.
  • Low-power-consumption unit enables extended run times with limited power source.
  • NEMA 4, watertight casing provides superior protection against the elements, making the CEO Two controller ideal for use in harsh environments. In addition, the internal electronic components are specially coated, preventing damage caused by corrosion, humidity and extreme temperatures.
  • Standard event logger accurately records plunger cycle time as well as plunger arrivals.
  • Automatic high/low shutdown with optional reset conditions allows operator preference on safety controls.
  • The controller can use a Murphy switch to optimize control beyond the timer settings.
  • Remote solenoid enables use of the controller in sour-gas applications without exposing it to damaging gases.
