The BSK Notus HV is a new generation residential heat recovery unit featuring an EPP body, a hexagonal counter-flow plate heat exchanger with up to 90% thermal efficiency, and airflow up to 375 m³/h. Built-in WiFi and the BSK Connect mobile app let you monitor and control the unit from your phone. The universal design supports both vertical and horizontal installation, and switching between right and left configurations simply by swapping the air ducts — all in a single unit.
Key Benefits
Smart control with BSK Connect
Standard WiFi connectivity lets you monitor and control the unit via the BSK Connect mobile app. For centralized management of multiple units, BSK Cloud offers a web-based tool designed for apartment buildings and facility managers.
Humidity control and defrost
The built-in humidity sensor automatically switches the unit to Boost mode when indoor humidity rises. In freezing conditions, the automatic defrost mode activates to prevent ice build-up inside the device.
Universal installation in one unit
The BSK Notus HV combines vertical and horizontal mounting and right/left configurations into a single device. Simply swap the interchangeable air ducts to adapt the unit to any space — no need to order a different model.
ModBus for BMS integration
The ModBus communication protocol allows seamless connection to your building management system (BMS). Monitor operational status, report malfunctions and schedule maintenance directly from a computer or central control system.
Counter-flow plate heat exchanger
The BSK Notus HV uses a hexagonal counter-flow plastic plate heat exchanger with up to 90% thermal recovery efficiency. Unlike rotary exchangers, it does not transfer moisture between air streams, ensuring maximum hygiene and complete separation of supply and exhaust air.
The double-walled metal casing with 25 mm insulation material combined with the EPP body significantly reduces thermal losses and noise levels. EC fans with energy-saving motors deliver reliable and quiet operation at minimal power consumption.
Optional Accessories
Control Options
BSK Connect app — standard WiFi connectivity lets you monitor and control the unit directly from your smartphone or tablet. Set ventilation modes, check temperatures and humidity in real time.
4“ touch control panel — optional wall-mounted panel for advanced control of all features directly from the room.
BSK Cloud — centralized web tool for monitoring, controlling and servicing multiple units from a single location. Suitable for apartment buildings, commercial properties and facility management companies.
