  • General characteristics

    Heosbox is a condensing unit for waterloop applications entirely engineered and manufactured by CAREL. 
    Heosbox incorporates all of the features of the Heos solution, starting with the controller and the components for continuous modulation: 

    • BLDC compressors. DC technology allows greater efficiency through permanent magnet brushless motors, the widest range of modulation (25-100%), high reliability due to a reduction in electrical and mechanical stress, low noise and extremely compact dimensions. Both vertical and horizontal solutions are available, with a wide range of brands and performance.
    • DC drivers. CAREL drivers for Heos applications feature high electrical efficiency and reliability of both the driver and the entire solution, thanks to perfect integration with the system (envelope control, safe torque off, crankcase heater...), as well as electromagnetic compatibility . 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, the evaporation temperature can be controlled continuously to ensure efficiency in all operating conditions. The use of electronic valves also allows preventive and alarm monitoring actions, for greater reliability of the entire solution. 
    • Heos controller. All-in-one solution for:
        - cabinet temperature and superheat control
        - compressor management (envelope, COP calculation, oil recovery procedures)
        - condensing stage control
        - lights, defrosts, fans and alarms

    Heosbox is available for R448A/R449A, R410A synthetic refrigerants, with both CE and UL certification. Capacities up to 10 kW in MT conditions (-10°C/40°C) and 3.5 kW in LT conditions (-30°C/40°C) to satisfy a wide range of applications. 
    Performance combined with ease of use thanks to the default pre-configuration for immediate use.

    Heosbox is also supplied with integrated services developed specifically for this solution, which include remote monitoring, data analysis tools and advanced algorithms for predictive maintenance.

    All the unique features and advantages of Heos technology:

    Continuous system modulation

    Variable speed compressors (BLDC) and electronic expansion valves with stepper motor.

    Energy efficiency

    The decentralised approach and continuous modulation make it possible to adapt operation perfectly to the demands of the cabinet in all conditions. Synchronisation of control actions and possibility to read COP in real time.

    Maximum food preservation quality

    Continuous modulation of the compressor and EEV electronic valves ensures excellent temperature and humidity stability in the cabinets.
