Heos Pro

Heos Pro represents the highly-efficient solution for plug-in and semi plug-in showcases, guaranteeing a considerable reduction in environmental impact, cutting direct emissions through the use of natural refrigerants, and indirect emissions through continuous modulation. This approach is the result of the synergy between the variable-speed DC compressor and electronic expansion valve, managed by an advanced controller.

The main components of the complete Heos package are:

• BLDC compressors with DC technology ensure higher efficiency through permanent magnet brushless motors, the widest possible range of modulation (25-100%), high reliability due to a reduction in electrical and mechanical stress, low noise and extremely compact dimensions. 
• DC drivers. CAREL drivers for Heos applications feature high electrical efficiency and reliability of both the driver and the entire solution. Class B firmware is available, with integrated protection and consequent savings in installation costs. 
• Electronic expansion valve with stepper motor. Operation is managed perfectly in synch with the variable-speed compressor.
• Heos controller. All-in-one solution for:
  • showcase temperature and superheat control
  • compressor management (envelope, EER/COP calculation, oil recovery procedures)
  • condensing stage control
  • lights, defrosts, fans and alarms
  • Ethernet and Bluetooth connectivity
  • A3 ready for flammable refrigerants

The Heos solution is available for natural (R290 and CO₂) or synthetic refrigerants.
