c-pro 3 CLOSE

Controllers for close control units
c-pro 3 CLOSE is a high-precision control solution designed for the management of the complete range of close control units: chilled water units, hybrid units or direct expansion units (single and dual circuit with on-off or BLDC variable speed compressors). Up to 16 units can be linked via CAN BUS in a smart network.
To provide optimum and safe control of temperature and humidity conditions, the solution is designed to control on-off and modulating fans with separated condensation and it has a management system for the secondary source, “dry cooler” and “free cooling”.
Each controller can manage up to 2 external driver modules (available in blind version or with built-in display) that make it possible to drive bipolar stepper electronic expansion valves.
Available in 4 or 8 DIN module size, the latter format has a rich equipment of communications ports which support protocols such as BACnet and Webserver.
