The HRU-BoxAIR-225 is the most powerful unit in the series, engineered for larger homes and residential spaces that demand a higher rate of air exchange. Delivering a commanding 225 m³/h airflow (at 100 Pa), it provides robust ventilation performance while retaining the celebrated compact dimensions and revolutionary installation flexibility of the BoxAIR family. For projects where performance is paramount, the fully-featured and highly efficient BoxAIR-225 is the ultimate choice.
Engineered for Unmatched Installation Freedom
The HRU-BoxAIR-225 features the same groundbreaking construction as the entire series, providing installers and architects with a powerful solution that is incredibly easy to integrate.
Universal Left/Right-Handed Design: The unit’s signature feature is its ability to be configured on-site for either left or right-handed installations. A quick 180° rotation is all that is needed, completely eliminating planning errors and the need for separate models.
Adaptable Ductwork with BFX: When equipped with optional BFX adjustable duct connections, the unit can accommodate complex duct layouts in any direction, making it supremely adaptable to even the most challenging site conditions.
Full Dual-Side Service Access: Technicians can perform all maintenance, including filter changes and diagnostics, from either side of the unit, providing unparalleled convenience and installation freedom.
Superior Acoustic Performance: The unit’s intelligent internal layout, with fans positioned on the external air side, allows the large heat exchanger to double as a sound attenuator, ensuring whisper-quiet operation in the home's living areas.
Top-Tier Technology and Efficiency
The HRU-BoxAIR-225 is built to deliver powerful, reliable performance with advanced technology that maximizes both energy savings and indoor comfort.
High-Efficiency Heat Recovery: A large counterflow plastic (PET) heat exchanger forms the core of the unit, achieving an excellent thermal efficiency of up to 92%. This ensures maximum energy recovery and lower heating bills throughout the year.
Comprehensive Feature Set as Standard: Every BoxAIR-225 comes fully equipped with a 1500W preheater for reliable frost-free operation, an automatic by-pass for free summer cooling, and an integrated RH sensor for humidity control.
Optional Constant Flow (CF) System: For installations demanding absolute precision, the unit can be upgraded with a Constant Flow system. This technology ensures the unit always delivers the commissioned airflow rate by automatically adjusting for factors like filter clogging.
Ready for Smart Control: The unit is fully compatible with a wide array of wireless controllers and on-demand sensors (CO2/RH). By connecting it to the internet, users gain full remote control via the intuitive Alnor mobile application.
