c-pro 3 CLOSE is a solution for close control management using direct expansion (single and dual circuit with 1 compressor for each circuit) or refrigerated water.
It consists of:
- a main controller (c-pro 3 kilo CLOSE, available in blind version).
- a driver for bipolar stepper electronic expansion valves for each circuit (EVDRIVE03, with built-in user interface or in blind version).
- remote user interface (Vgraph O).
This solution is capable of managing both on-off and variable capacity compressors. It is also able to control on-off and modulating fans with separated condensation.
It has a management system for the secondary source, dry cooler and free cooling.
The main controller is designed to be installed on a DIN rail in a control panel.
