    Ultimate performance

    Whilst the HRX2D is easy and quick to install, commission and maintain, it also provides Specific Fan Powers as low as 0.57W/(l/s) and a high heat exchange efficiency up to 94%; lowering Dwelling Emission Rates for a higher SAP rating.

    Offering control functions such as frost protection, temperature and humidity control, auto thermal bypass and independent fan speed control, the Bluebrain controller boasts a full complement of air quality and commissioning controls for improved air comfort.

    This heat recovery unit and semi rigid radial ducting kit meets the highest and latest Building Regulation requirements and are suitable for newly constructed homes and renovation projects.

    Intelligently manages air conditions

    Digital humidity control aiding homeowner comfort Through advanced AMIE technology, unlike typical humidity sensors, the Bluebrain HRX2D controller will enable occupants to have direct control over managing the humidity levels in their home - to suit personal comfort levels. By accurately measuring air humidity, the HRX2D’s extract speed automatically changes from background to boost as the level of humidity increases, thereby providing optimal ventilation performance. Advanced thermal bypass control Perfect for night time cooling or during warmer periods, the HRX2D controller detects when the air temperature reaches a pre-set level and intelligently activates the thermal bypass mechanism to maximise the effect of maintaining fresh and filtered air. The thermal bypass is also programmable by time, for additional convenience and comfort

    Commissioning made easier

    Engineered to include independent speed control, the Bluebrain control allows quick and accurate commissioning through simple speed adjustment buttons.

    Automated filter maintenance and replacement reminders

    Ease of maintenance and filter replacement is an important consideration when choosing MVHR – not only to ensure performance of the unit is maximised and air quality maintained, but also for peace of mind.

    The HRX2D Bluebrain control removes this concern by providing helpful maintenance reminders for cleaning its filters. 

    Building Management Systems (BMS)

    The HRX2D controller incorporates volt free contacts for fault and filter cleaning indication, to work with a Building Management System
