Ejector Manager: a new proposal in the CO₂ range
The new Ejector Manager joins the CAREL range as a specialised control solution for systems equipped with vapour, liquid or combined ejectors, alongside the tried-and-tested pRack for more complex applications, and the compact µRack CO2 for entry-level applications.
Based on the next-generation STone software platform, Ejector Manager provides an intuitive user interface for quick and smooth setup. When combined with the use of the APPLICA Desktop and SPARK tools, users are supported at every stage of configuration, significantly reducing setup times and simplifying day-to-day system management.
Main features
Ejector Manager stands out for its advanced and perfectly integrated management of ejectors, covering different types and configurations. The system is designed to control up to six vapour ejectors and up to two liquid ejectors, as well as combined configurations that operate in both modes. This flexibility means the controller can adapt to different system needs, always guaranteeing the highest performance.
One key aspect of the Ejector Manager is its priority logic, developed to automatically select the most suitable ejector based on current system operating conditions. This allows continuous optimisation of operation, maintaining high energy efficiency even when there are variations in load or variable environmental conditions.
The Ejector Manager architecture has been designed to be modular and expandable. Indeed, up to three I/O expansion cards can be connected, depending on the number and type of ejectors managed. The digital outputs can be configured flexibly, choosing between standard or SSR outputs, to suit the specific needs of the system.
Finally, the system is designed to operate with on/off ejectors, managing up to eight activation steps. The possibility to set custom opening sequences allows fine flow control, improving overall system performance.
One of its most notable features flooded evaporator mode. This is especially advantageous, as it allows refrigerated cabinets to operate at low superheat values, significantly improving evaporator heat exchange efficiency. Through dedicated control of liquid ejectors, the system can guarantee stable and optimised operation, increasing overall system efficiency.
