- EC Fans: Direct-driven EC plug fans with high-efficiency electronic commutation (EC) provide an energy-efficient and quiet solution with low power consumption.
- Counterflow Heat Exchanger: The integrated, efficient counterflow heat exchanger recovers 85% of the thermal energy from the exhaust air without mixing air streams.
- Panel Filter F7/M5: Ensures a high level of filtration for dust particles and contaminants from outdoor air, contributing to a healthy and comfortable indoor climate and protection of internal components.
- Automatic Summer Bypass: Enables summer and night cooling by supplying cool outdoor air directly without warming through the heat exchanger.
- Plug-and-Play Control: The air handling unit is delivered complete with built-in controls for all functions, allowing quick and easy installation and commissioning without additional control technology.
