The HRU-PremAIR-350 is a modern, high-performance ventilation unit designed for installations requiring a balanced airflow of 350 m³/h at 100 Pa. It integrates a high-efficiency counterflow heat exchanger within an innovative, self-supporting EPP casing, ensuring top-tier thermal performance and acoustic insulation. Controlled by an advanced PCB, the unit offers seamless wireless communication and full remote control via a mobile app, making it a perfect fit for smart, energy-efficient homes.
Core Technical Advantages
Outstanding Efficiency: Achieves a certified thermal efficiency of 88.9% (according to EN 13141-7), ensuring maximum energy savings and compliance with the ErP2018 directive.
Advanced Counterflow Exchanger: The highly efficient PET counterflow heat exchanger forms the core of the unit, maximising heat transfer between air streams.
Automated Comfort: Features a fully modulating by-pass for automatic activation of free-cooling in summer and free-heating during transitional periods, enhancing user comfort without manual intervention.
Lightweight & Robust: Despite its high mechanical resistance, the unit weighs only 35 kg, simplifying transport and installation. Wall mounting racks and feet are included as standard.
Simplified Maintenance: Designed with replaceable duct connections and easy access to filters for straightforward servicing.
Innovative EPP Casing & Construction
The HRU-PremAIR-350 is built using a hi-tech casing made from Expanded Polypropylene (EPP). This cutting-edge material is key to the unit's performance, offering several distinct advantages for both installers and end-users.
Superior Insulation: EPP provides excellent thermal insulation, preventing heat loss and eliminating thermal bridging, which contributes directly to the unit's high efficiency.
Acoustic Dampening: The material's structure effectively absorbs operational noise, resulting in a quiet environment with a sound power level of just 44 dB(A).
Durability: The casing is highly resistant to mechanical damage and is non-degrading, ensuring long-term structural integrity.
