Heos Pro, the high efficiency solution
Heos Pro, the high efficiency PI&SPI solution
The refrigeration market is continuously demanding solutions to cut direct and indirect emissions through innovation and efficiency. In this challenging context, CAREL has developed the Heos Pro solution to bring the best-in-class technologies to plug-in and semi plug-in units.
This solution brings together all the modulation approaches for cabinet control:
-
Dedicated controller
Intuitive interface, configuration via APPLICA app
Ethernet and Bluetooth connectivity, real-time updates and diagnostics
Natural refrigerant management and continuous modulation for reduced energy use
-
Inverter + DC rotary compressor
Wide modulation range (25–100%), high performance, acoustic comfort, compact footprint
-
Stepper EEV valve
Precise control synchronised with compressor for optimised efficiency and stability
-
Pressure/temperature sensor
Versatile versions, including welded, for accurate monitoring under various conditions
-
CO2/R-290 unit
Designed for low emissions and measurable environmental impact reduction

All these components create the Heos Pro solution, which guarantee “tangible sustainability” through a continuous modulation approach, always operating at highest efficiency while ensuring the best food preservation.
Flexibility is also guaranteed, giving users the opportunity to use both R-744 and R-290 refrigerants in the same solution, qualifying the kit as “refrigerant neutral”.
Advanced connectivity is also at the core of the solution, thanks to the Bluetooth/NFC setup, Ethernet Modbus TCP/IP supervision, faster polling, and quick firmware updates.
CAREL has made adoption of this solution easy by design, ensuring frictionless integration with R-290 units. The components in fact are “A3 ready”, the controller and display are compliant with EN 60 335 2 89 Annex BB, ensuring flexibility and safety.
Propane is just one of the possible path to bring to the market “tangible sustainability”, in fact a CO2 solution with Heos Pro has also guaranteed efficiency and energy savings, as shown in this study with the HEOSBOX R-744 deeply integrated with the HVAC system.
Heos Pro is more than just a refrigeration solution: it’s a technological ecosystem designed to be easy to use and sustainable, while reducing emissions, energy consumption, and operational complexity, right at the point of sale.
