The BSK BRHR Plus High-Efficiency ceiling-type HRU is designed for residential and light commercial applications requiring powerful ventilation and maximum energy savings. Engineered to deliver airflows up to 4000 m³/h, it efficiently recovers up to 90% of thermal energy using high-performance hexagonal counter-flow heat exchangers.
Its double-walled galvanized steel casing, insulated with 25 mm acoustic and thermal foam, ensures silent operation and robust durability. Equipped with EC fans, a free-cooling bypass damper, and intelligent control modes like boost and defrost, the BRHR Plus HE offers complete control over your indoor climate.
The system supports digital and Wi-Fi control panels, integrates with ModBus/BMS systems, and features weekly scheduling, temperature & humidity sensors, and optional add-ons like CO₂ sensors, electric/water heaters, and F7 pollen filters.
Ideal for large homes, offices, retail spaces, and institutions needing high-capacity, low-noise, and smart ventilation.
