Blauberg KOMFORT EC SB350 S11
- Capacity diagram
- Designation key
Air handling units for efficient energy saving supply and exhaust ventilation in flats, houses, cottages and other premises.Heat and humidity recovery minimizes ventilation heat losses during cold season and reduces air conditioner load during hot season.Controllable air exchange for creating the best suitable indoor microclimate.Compatible with round Ø125, 160 or 200 mm air ducts.
The casing is made of double-skinned polymer-coated steel panels, internally filled with mineral wool layer.The spigots are located at the top of the unit and are rubber sealed for airtight connection to the air ducts.Depending on the unit model, the units may be equipped either with a hinged service panel to enable convenient access for maintenance operations or with a separate door for quick access to filters KOMFORT EC S(B)250(-E) S11.
The units are equipped with high-efficient EC motors with an external rotor and a centrifugal impeller with backward curved blades.EC motors have the best power consumption to air capacity ratio and meet the latest demands concerning energy saving and high-efficient ventilation.EC motors are featured with high performance, low noise level and optimum control across the entire speed range.The impellers are dynamically balanced.
Two built-in G4 and F7 filters provide efficient supply air filtration. The G4 filter is used for extract air filtration.Supply air in the KOMFORT EC S(B)250 units is purified by the G4 and F7 filters. The G4 filter is used for extract air cleaning.
|HEAT RECOVERY||CONTROL AND AUTOMATION|
The KOMFORT EC S(B) ... S11 unit is equipped with a plate counter-flow polystyrene heat exchanger for heat recovery. In the unit condensate is collected and drained to the drain pan under the heat exchanger.The KOMFORT EC S(B)-E ... S11 unit is equipped with an enthalpy plate counter-flow heat exchanger for enegry (heat and humidity) recovery. Due to humidity recovery condensate is not generated in the enthalpy heat exchanger.
The air flows are completely separated in the heat exchanger. Thus smells and contaminants are not transferred from the extract air to the supply air.Heat recovery is based on heat and/or humidity transfer through the heat exchanger plates. In the cold season supply air is heated in the heat exchanger by transferring the heat energy of warm and humid extract air to the cold fresh air. Heat recovery minimizes ventilation heat losses and heating costs respectively.In the warm season the heat exchanger performs reverse and intake air is cooled in the heat exchanger by the cool extract air. That reduces operation load on air conditioners and saves electricity.When the indoor and outdoor temperature difference is insignificant, heat recovery is not reasonable. In this case the heat exchanger can be temporary replaced with a summer block for the warm season (available as a specially ordered accessory).FROST PROTECTION
The integrated automatic freeze protection is used to prevent freezing of the heat exchanger in the cold season. The supply fan turns off according to the temperature sensor to get the heat exchanger warmed up with extract air. After that the supply fan turns on and the unit continues to run in the standard mode.
The units incorporate an integrated control system with the S11 wall-mounted control panel with an LCD display.S11 automation functions:
The KOMFORT EC SB ... (-E) S11 units are equipped with a 100 % bypass for summer ventilation (air cooling by the cool air from outside).
The units can be fixed to the wall or mounted on the floor using the mounting brackets.While mounting provide free access to the service panel for filter replacement and servicing.Due to universal casing design both left and right mounting is possible. It requires swapping the service and the back panel.
