Blauberg KOMFORT EC LB300 S11
Air handling units for efficient supply and exhaust ventilation in flats, houses, cottages and other buildings.For arranging of controlled energy saving ventilation systems.Heat recovery minimises ventilation heat losses.Controllable air exchange for creating the best suitable indoor microclimate.Compatible with round Ø160, 200 and 250 mm air ducts.
The casing is made of double-skinned aluzinc panels, internally filled with 25 mm mineral wool layer for heat and sound insulation.Casing has fixing brackets with vibration absorbing connectors for easy installation.The hinged casing panel ensures easy access to the internals for cleaning and other maintenance operations.The spigots for connection to the air ducts are located at the side of the unit and are rubber sealed for airtight connection to the air ducts.The bypass damper is opened automatically in summer time to cool down a room with cool outside air. For the model with a heater the bypass damper is also used for the heat exchanger freezing protection.
High-efficient external rotor EC motors and centrifugal impellers are used for air supply and exhaust.The forward curved blades in KOMFORT EC LB300/LB400/LBE300/LBE400 S11 provide permanent air flow.The KOMFORT EC LB600/LBE600 S11 model has impellers with backward curved blades.EC motors have the best power consumption to air capacity ratio and meet the latest demands concerning energy saving and highefficient ventilation.EC motors are featured with high performance, low noise level and totally controllable speed range.Dynamically balanced impellers.
The KOMFORT EC LBE S11 model is equipped with an electric heater for operation during cold seasons at low outside temperature.The integrated electric heater is activated to warm up supply air flow if set indoor air temperature may not be reached by means of heat recovery only.Smooth heat output control ensures automatic supply air temperature maintaining.Two integrated overheat protection thermostats, one actuated at +60 °C with automatic restart and the other one actuated at +90 °C with manual restart.
The built-in G4 pocket supply filter and G4 cassette extract filter provide efficient air filtration. Optionally, an F7 supply filter may be used.
The unit is equipped with a counter-flow polystyrene heat exchanger with a large surface area and high heat recovery efficiency.Heat recovery is based on utilization of heat energy contained in the extract air stream for heating up of supply air stream. Extract air transfers most of its heat to the intake air flow. Heat recovery reduces heat energy losses in cold seasons.In summer the heat exchanger performs reverse and intake air is cooled in the heat exchanger by the cool extract air. This contributes to better performance of the air conditioner in ventilated premises.The drain pan under the heat exchanger block is used for condensate collection. The drain pan is fitted with a drain pipe for condensate removal.The electronic freeze protection system is used to prevent the heat exchanger freezing in the cold season:
CONTROL AND AUTOMATION
The units incorporate an integrated control system with a wallmounted control panel and sensor display.The standard delivery set includes a 10 m cable for connection of the unit and the control panel.Automation functions:
The unit is suitable for floor, ceiling or wall mounting using fixing brackets.The correct mounted unit must provide free condensate collection and drainage as well as good access for servicing and filter replacement.The service access is on the side of the removable service side panel, leftwards along supply air flow.
