R1 Compressor Controller / Single Pump Kit



Model R1

The Compresor Controller is a control system designed for electric single pump reciprocating air compressors, The only 3rd party tested system that saves energy, improves air quality and reports operational problems.

The Compressor Controller retrofit kit delivers full system automation and can be installed on virtually any brand reciprocating air compressor.


  • Reduce tank moisture up to 70%
  • Reduce startup current up to 20% reduction (lower utility demand charges)
  • Eliminate drifting pressure band gap (save energy all year long)
  • Self-reporting of maintenance needs

Features & Benefits

Features & Benefits

Intelligent air tank moisture control:  With Real-Time feedback, it directly controls the air tank drain valve to expel condensate when it is present without excessive waste of air in the process. This maintains a much drier air quality and significantly reduces the lifetime energy footprint of the air compressor by reducing the number of pump cycles.


Compressor pump smart start guards against oil contamination: Controls the compressor pump unloader valve with Real-Time feedback on the power consumption to guarantee a properly timed loading sequence that reduces startup current draw (up to 20% ) and lowers the oil moisture contamination in pumps.


Automatic air line rupture detection:  Detects air line ruptures in the air network and stops the pump preventing further damage to equipment and personnel.


Automatic overheat protection:  The controller observes the pump head temperature and automatically manages any connected auxiliary fans to assist with maintaining the pump temperature below a threshold.


Digital management of pressure band gap: Precise digital monitoring of the system pressure digital system allows the Compressor Controller to control the low and high set points without drifting, even when accounting for weather and climate changes/differences.


Cycle and Hour usage meter: The Compressor Controller counts both the pump cycles and operating hours, displaying this information on the LCD screen.  This information allows passive insight into performance and can be used to appropriately schedule maintenance.


Compressor City: Each Compressor Controller is equipped with a compressor city function

allowing owners of multiple reciprocating air compressors of different types, sizes, and brands to connect them seamlessly together as a system to always satisfy peak-demand air requirements and synchronize maintenance intervals.

Installation Overview

Installing the Compressor Controller can be broken down to the following steps:

  1. Cut an opening in an enclosure* to mount the compressor controller, temperature sensor, power supply, buzzer and magnetic starter * / Solid State Relay (SSR) * / Variable Frequency Drive (VFD) *.
  2. Install the digital pressure sensor on the tank, often added to a tee where the original pressure gauge is located.
  3. Remove a bolt that attaches the pump head to the pump base and install the pump temperature sensor much like a washer and reinstall the bolt.
  4. Add an electrically operated unloader valve* if the unloader is operated mechanically or if an existing electrically operated valve is present it can be used.  (check for electrical compatibility).
  5. Add an electric valve* to the tank drain or if an existing electric valve is present it can be used (check for electrical compatibility).    
  6. Connect and check the wiring.

* Components that are not included with the compressor controller kit and may be needed
