Electronic Controller Systems

Master-Bilt electronic controllers are designed to increase food safety while reducing energy and installation costs. As an integrated part of refrigeration systems, controllers boost system efficiency and provide many other benefits. Two types of controllers are provided:

  • Enviro-Control™ is standard on all self-contained Capsule Pak™ systems.
  • Master Controller for remote Split-Pak™ systems is standard on freezer systems 6 H.P. and above and optional on other systems.
Capsule Pak refrigeration systems are standard with an electronic controller

Capsule Pak™ refrigeration systems are standard with Enviro-Control.

Split-Pak refrigeration system with electronic controller.

Many Split-Pak refrigeration systems are equipped with the Master Controller.

Food Safety

  • More precise and reliable controls than an all-mechanical system for increased food safety
  • Should there be an issue with the refrigeration system, operators will know instantly through error codes and data provided online

Installation Savings

  • Enviro-Control is an integrated component of all Capsule Pak systems, no installation is required
  • On Split-Pak systems, no wiring is required between evaporator coils and condensing units (2 pairs of low voltage wires, typically thermostat cables, are required to operate the Reverse Cycle Defrost valve and the compressor relay at the condensing unit).
  • On Split-Pak systems, a Master Controller-equipped system uses less refrigerant with no winter charge necessary

Energy Savings

  • Master Controller’s patented design saves up to 27% more energy than an all-mechanical system
  • Demand Defrost technology initiates defrosts only as needed for further energy savings
  • Defrost time, when initiated, is also greatly shortened
  • Master Controller with Reverse Cycle Defrost provides additional savings
  • On Split-Pak systems, save 2-4% more energy with the fan cycle option which saves electricity by cycling the evaporator fans during the compressor’s off cycle


Track refrigeration system performance remotely with electronic controllers.

  • Software loaded on each controller allows remote monitoring and programming using any device with a wireless internet or cabled (cat 5) connection
  • No need for a service tech to climb onto a roof or enter the walk-in to monitor or adjust the refrigeration system
  • Constant data access allows users to improve refrigeration performance and avoid service issues
