plunger lift controllerRELIABLE

The ultra-reliable ALiEn2 plunger lift controller keeps production at it’s peak and operator intervention to a minimum. Designed to withstand extreme conditions, ALiEn2 functions reliably in temperatures as low as -40°C and up to +70°C (-40°F to +160°F). ALiEn2’s unique display technology ensures full operation over this entire temperature range. In areas that experience long periods of low sunlight, ALiEn2 draws so little energy from its rechargeable battery that it will operate for more than 8 months*,** without a charge. Recharge with ETC’s compact 1.1 W solar panel, which comes standard with every ALiEn2 plunger lift controller.

SIMPLE

Installation and setup of ALiEn2 is fast and simple. The universal mounting bracket included with every ALiEn2 supports a variety of mounting locations from shack to well head. Features like the install key, dual purpose numeric/navigation keypad, and a user-friendly menu make configuration effortless. The electronics module removes quickly and easily for upgrading and maintenance, no tools required.
Quick Install Guide


RUGGED

Each ALiEn2 is protected by a Type 4 (dust and splash proof), powder coated steel enclosure featuring a locking door. Pre-punched holes provide a variety of options for fastening solenoids and wiring connectors. Solenoids are securely mounted outside the enclosure to make regular maintenance quick and easy, and avoid corrosion of electronic components.

OPERATION

ALiEn2 is the most feature-rich plunger lift controller in it’s class. Use as a simple well intermitter or in conjunction with a plunger and arrival sensor to optimize production. Protect your well by using a line pressure device to shut in on high line pressure. Log your plunger’s mileage with Plunger Tracking, and use Vent Tracking to keep tabs on vent time. As new features become available, upgrading your controller is fast, easy, and convenient with Vision software.

REMOTE ACCESS

Every ALiEn2 includes a standard Modbus communication port for remote monitoring and control, and is preconfigured to work with several popular SCADA solutions. ALiEn2 can also be configured to work with your internal SCADA system. No SCADA? No problem! ALiEn2 is fully functional and accessible right on site.

OPTIMIZATION

ALiEn2’s intelligent and effective optimization algorithms will help you achieve maximum production.

Adaptive Seeking Velocity Optimization™

This patented algorithm reduces the need for operator intervention (thus eliminating opportunities for human error) by making automatic adjustments that are proportional to the current flow/close time. This method was used with average plunger velocity to double gas well production in a 2015 case study. When Adaptive Seeking Velocity Optimization™ is used with a plunger arrival sensor such as Cyclops®, ALiEn² reacts to the average velocity of the plunger, making proportionate changes to the amount of Close and Afterflow time for the well. The user specifies a Target Rise Velocity, which ALiEn² then works to achieve. For best results, use a Sasquatch® Plunger Velocity Sensor in conjunction with Adaptive Seeking Velocity Optimization™ to maximize production using real-time Surface Velocity. ALiEn² is the first plunger lift controller capable of optimizing on Surface Velocity; a standard feature in the ALiEn² Expert model, and also available as an upgrade for the ALiEn².
Why Optimize on Velocity?

Pressure Optimization

Use a combination of Line Pressure, Casing Pressure**, Tubing Pressure**, and Differential Pressure** to optimize the well. ALiEn2 automatically adapts to use enabled devices. Optimize on Flow Rate (AGA 2 table based) when using a Line Pressure and Differential Pressure sensor.
