c-pro 3 CHIL

Controllers for single- and dual-circuit chillers/heat pumps
c-pro 3 CHIL are controllers for running single- and dual-circuit air to water and water to water chillers/heat pumps, up to 3 compressors for each circuit.
It consists of:
- a main controller with a choice of a c-pro 3 nano CHIL (with a built-in user interface and touch keys) or a c-pro 3 micro CHIL (available with a built-in user interface or a blind version)
- a possible I/O expansion (c-pro 3 EXP micro+, available in blind version)
- a possible bipolar stepper electronic expansion valves driver for each circuit (EVDRIVE03, available with integrated user interface or in blind version)
- a possible remote user interface (Vgraph).
The system is able to manage “on-off” compressors; it is also able to manage both “on-off” and modulating fans, with single or independent condensation.
It can manage the pump down solenoid valve, “free cooling” and the “weekly programming” function.
c-pro 3 nano CHIL is designed to be installed on a panel with snap-in brackets, while c-pro 3 micro CHIL is fitted to a DIN rail in a control panel.
