CAREL pR300T PRK30T*

pR300T is ideal for managing carbon dioxide-based booster systems.
The new pRack pR300T platform offers on the market CO2 transcritical plants as a product that will be continuously improved, allowing the user to easily manage inherently complex machines:

• Complete management of transcritical CO2 plants in a single control
• Use of simple and intuitive user interface (also customisable)
• Quick access to monitoring systems
• Quick access to programming (USB host and device)
• Safety and backup procedures
• High flexibility (multi-board, customisability I/O)

The advantages of pR300T control system are:

• Oil management (cooling-injection-separation)
• Heat recovery (double exchanger and gas cooler bypass)
• Control of the HPV valve (optimal algorithm for pressure calculation)
• Flash valve adjustment (pressure of the receiver- safeties connected to HPV)
• Restore procedures (fault synchronisation with controller case)
• Integration with Chillbooster (Adiabatic cooling system for air condensers)
• Activation of parallel compression (auxiliary compressors for receiver pressure adjustment)

Direct management of the HPV and RPRV valves: Thanks to the driver for stepper expansion valves integrated in the tool, installation of external drivers for valves management is not necessary. Ultracap technology maximises the plant safety levels.
