BeaconII Refrigeration System

Refrigeration Controls & Technology

Beacon II™ Refrigeration System is a patented, pre-assembled, factory-installed refrigeration control system featuring an integrated microcomputer-based electronic control board and an electric expansion valve at the heart of the system. With components factory mounted at both the condensing unit and evaporator, the Beacon II™ system can be used with single or multiple evaporator applications. While perfect for restaurants and convenience stores, the Beacon II™ system can be scaled up to meet the needs of larger refrigerated warehouses with optional system devices such as the Beacon II™ Smart Controller.

Features and Benefits

Reduced Installation Time/Cost


    Factory mounted components, testing, and programming substantially reduces field assembly and fine tuning at the job site Increased System Efficiency & Reliability


  • Beacon II™ electronic control board and electric expansion valve more accurately controls the flow of refrigerant verses traditional thermal expansion and solenoid valves
  • Preset factory superheat allowing the system to run more efficiently and reducing future adjustments


Reduced Energy & Operating Costs


  • Reduce up to 75% of unnecessary defrosts per day verses traditional timer systems with the Beacon II™ Smart Defrost
  • Improved Product Integrity & Reduced Spoilage
  • Precise temperature control improves product integrity while alarm notifications helps prevent small problems from turning into large problems
  • Strengthen Food Safety Compliance Programs
  • Data-logging capability helps comply with FDA and USDA HACCP food safety requirements
  • Compatible with the Remote Refrigeration Control
  • Web based remote monitoring and control service offering that provides instant access 24/7 to real time refrigeration system status and information
