  • Full BMS smartphone, Modbus and tablet capability with touch screed LCD display.
  • Designed specifically for smaller residential properties that require low noise levels.
  • Pure air G4 and F7 pollen and allergy filtration system reducing particulate matter down to PM2.5.
  • 40mm acoustically insulated casing that dramatically reduces noise levels.
  • Airflow rates up to 300 m3/hour (84 l/s) with a 2.8Kw electric heater.

Main Features

Typically Blauberg Komfort LB heat recovery units are used for small and large residential houses, offices and commercial ventilation systems where noise levels are an issue. A 40mm highly acoustically insulated casing is used to significantly reduce noise levels so that quiet, virtually silent continual operation is achieved.

New for 2019 is our smart home control system. This substantial upgrade enables you to program and control indoor air quality from your smart phone or ipad using wifi, or from anywhere in the world using the built-in smart hub and router. All Blauberg EC SB heat recovery units are now fitted with a built-in wireless router offering not just simple operation and control but full BMS Modbus connectivity to any compatible building management system.

Komfort LB Units are also supplied with a pre-wired touch screen LCD programmable controller. The S25 panel enables full functionality, programming, commissioning and fault finding with simple menu driven options.

High levels of filtration can be achieved as both a G4 and F7 filters are included as standard. This higher level of particle filtration cleans out pollen increasing efficiency down to PM2.5. For heyfever and allergy sufferers why not try the H13 HEPA filters for filtering pollen, airborne particles and other small particulate matter down to 0.3 microns.

Two energy saving German EC fans are at the heart of the heat recovery unit, powerful enough to deliver airflow rates up to 83 l/s. This makes Komfort LB units suitable for residential developments such housing projects, student & nursing accommodation, flats, offices and commercial civic installations.

Significant heat and energy is recovered from the dirty moist air as it passed through the heat recovery ventilation unit. Typically, in an air tight house over 90% of heat can be recovered and reused. Using traditional ventilation systems or extractor fans, this recovered energy would normally be extracted outside and wasted.
