EOS BCompact unit with hydronic heat recovery
High efficiency, advanced quietness, integrated multizone control.
The complete solution for high-efficiency homes: fresh air renewal, heating, cooling and humidity control in one compact module. High performance, energy savings and total comfort in every room.
One single unit for complete indoor comfort
EOS B integrates in one system:
- air renewal and filtration
- cooling and dehumidification
- heating
- multizone control (also via App)
- VAV (Variable Air Volume) ventilation
All in a compact footprint, ideal for new builds and renovations.
High-efficiency heat recovery
The cross-flow polystyrene heat exchanger operates between –30°C and +50°C with an efficiency above 90%.
An integrated anti-freeze cycle protects the exchanger when outdoor air drops below –5°C.
Automatic free-cooling for energy savings
When outdoor temperature is lower than indoor temperature, the motorized damper automatically activates free-cooling, bypassing the heat exchanger and cooling rooms using only the fans.
Quiet ventilation
Latest-generation EC fans and advanced regulation logic ensure extremely low sound emissions, down to < 30 dB(A) in VAV mode.
Advanced management and integrated control
The system features an auto-adaptive regulation that manages:
- airflow
- temperature and humidity
- recirculation
- filtration
- free-cooling
Control is available via user console, smartphone/tablet App or Modbus BMS.
EOS B ensures ideal indoor climate all year long, combining heat recovery, modulating ventilation and hydronic air conditioning. It cools, heats and dehumidifies with maximum efficiency, maintaining stable comfort and optimal air quality.
Summer
Cooling capacity: 3.2–6.3 kW, with dehumidification and VAV for maximum comfort.
Recirculation airflow: 500–1000 m³/h.
Winter
Heating capacity: 4.0–8.0 kW (50°C water).
The heat recovery preheats outdoor air, reducing load on the heat pump.
Mid-seasons
- Fresh-air renewal with heat recovery
- Automatic free-cooling
- Humidity management via dedicated sensor
