• General characteristics

    pR300T is the ideal controller for managing CO2 booster systems.
    The pRack pR300T platform is proposed on the transcritical CO2 system market as an increasingly high-performance product that helps users manage intrinsically complex units:

    • Complete management of transcritical CO2 systems on a single controller.
    • Simple and intuitive user interfaces.
    • Easy access to supervisory systems via BMS and programming (via serial or USB).
    • Safety and backup procedures.
    • High flexibility (multiboard layout, I/O configurability).


    pRack 300T comes with a long list of functions, including:

    • HPV valve control (optimal algorithm for pressure calculation).
    • Pressure control at liquid receiver via flash valve or parallel compression line.
    • Management of additional backup or supplementary high pressure and flash gas valves.
    • Oil management (cooling-injection-separation).
    • Heat recovery (dual heat exchanger and gas cooler bypass).
    • Integration with Chillbooster (adiabatic cooling system for air-cooled condensers).
    • Water chiller system feature.
  • Plus

    All of CAREL’s experience in CO2 management

    pR300T manages everything a transcritical system needs, from the flash valve to the high pressure valve, with advanced algorithms to maximise operating efficiency.

    Custom functions

    pRack offers the possibility to configure truly custom logic, adding further flexibility to the design of the compressor rack.

    Local and remote supervision

    Advanced local and remote supervision experience through integration with Boss and RED systems.

    High Efficiency Solutions

    Advanced configurations available based on pR300T using modulating DC compressors (multiDC) and EmJ ejectors.
