pR300T
PRK30T*
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.
