pR300T

• Complete management of transcritical CO₂ systems on a single controller
• Simple and intuitive user interfaces (including custom versions)
• Easy access to supervisory systems
• Easy access for programming (USB host and device)
• Safety and backup procedures
• High flexibility (multiboard, I/O configurability)

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

• HPV valve control (optimal algorithm for pressure calculation)
• Oil management (cooling-injection-separation)
• Heat recovery (dual heat exchanger and gas cooler bypass)
• Flash valve control (receiver pressure - safety linked to the HPV)
• Recovery procedures (fault synchronisation with case controller)
• Integration with Chillbooster (adiabatic cooling system for air-cooled condensers)
• Activation of parallel compression (auxiliary compressors for receiver pressure control)

• 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
• Multiboard layout
  pRack boards can be combined together in a highly versatile way serve the different unit configurations available on the market
• Custom functions
  pRack offers the possibility to configure truly custom logic, adding further flexibility to the design of the compressor rack
• High Speed variant
  all of the established experience of pRack in a new variant that is five-times faster. Faster processing, faster software loading, higher performance.
• Local and remote supervision
  Advanced local and remote supervision experience through integration with boss and RED
• High Efficiency Solutions
  pR300T is the basis for high-end solutions with the highest levels of efficiency, featuring EmJ modulating ejectors as well as fully-modulating MultiDC racks
