HRU-BoxAIR Heat Recovery Unit – The Universal Solution for Modern Ventilation
The HRU-BoxAIR series represents a paradigm shift in residential ventilation, combining a cutting-edge, universal design with exceptional performance. Available in three variants—150, 200, and 225 m³/h—all housed within the same compact external dimensions, this unit offers unparalleled flexibility for installers and architects. Its innovative construction and high-efficiency components ensure optimal thermal comfort and superior indoor air quality for any modern home.
Innovative Design for Ultimate Flexibility
The BoxAIR was engineered from the ground up to solve common installation challenges, simplifying everything from planning to commissioning.
Universal Left/Right-Handed Unit: The groundbreaking design allows the unit's configuration to be switched from left to right-handed directly on-site. This is achieved with a simple 180° rotation and minor adjustments, eliminating planning errors and the need for separate model versions.
Adjustable Duct Connections: Optional BFX connections provide multi-directional elbows that allow for a flexible ductwork layout in any direction, making it perfectly adaptable to complex and tight installation spaces.
Intelligent Acoustic Design: Both supply and exhaust fans are located on the outdoor air intake/exhaust side of the unit. This clever arrangement means the high-performance heat exchanger also functions as a powerful sound attenuator, significantly reducing noise levels in the connected living spaces.
Dual Service Access: Full access for maintenance, including filter changes and service checks, is conveniently provided from both sides of the unit, removing access constraints.
Performance and Technology
At its core, the HRU-BoxAIR is a powerhouse of efficiency, equipped with technology that guarantees optimal performance and energy savings.
High-Efficiency PET Exchanger: A large, counterflow heat exchanger made from durable plastic (PET) ensures maximum thermal efficiency of up to 93.2%, leading to significant savings on heating costs.
Fully-Featured Standard: Every BoxAIR unit comes equipped with a built-in electric preheater to prevent freezing, an intelligent automatic by-pass for free cooling in the summer, and an internal RH sensor for precise humidity monitoring.
Constant Flow (CF) System: Optionally, the unit can be equipped with a Constant Flow system. It continuously monitors pressure in the ducts and automatically adjusts fan speeds to maintain a constant, balanced airflow, ensuring the system runs at peak efficiency at all times, regardless of filter condition.
Advanced Control Options: The unit is compatible with a wide range of wireless and wired controllers, as well as on-demand sensors (CO2, RH). With an internet connection, it can be managed remotely via a mobile app.
