c-pro 3 CHIL

The c-pro 3 CHIL from EVCO is a control solution 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:

• the 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)
• I/O expansion if required (c-pro 3 EXP micro+, available in blind version)
• bipolar stepper electronic expansion valves driver for each circuit (EVDRIVE03, available with integrated user interface or in blind version)
• remote user interface if required (Vgraph).

The solution is based on programmable controller technology and remote user interfaces belonging to the c-pro 3 series. The controller can 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.
