µChiller is the solution for the complete management of chiller units and air/water and water/water heat pumps with on-off compressors and/or DC compressors.
Features
- integrated management of BLDC compressor and electronic valve,
- integrated connectivity to supervisory systems,
- Dedicated APP for installer/maintenance technician (Carel APPLICA),
- Integrated double row LED display,
- possibility of having the pGDX as a machine or remote terminal,
- Compatibility with natural refrigerants and low GWP mixtures.

With µChiller it is possible to completely control the high efficiency unit to improve its performance and reduce energy consumption. As an example:
- Increases in the machine’s COP during partial load operation, which result in higher seasonal efficiency values,
- Complete control of the compressor envelope,
- Advanced DC inverter compressor management with EEV synchronization and protections.
The µChiller controls supports the Modbus serial communication protocol.
