Blauberg CIVIC EC LB 300-E S21 V.2

The CIVIC EC LB V.2 units are designed for single-room ventilation of schools, offices and other public and commercial premises. Offer the ideal simple and efficient ventilation solutions for existing and renovated buildings and require no layout of air ducts.Efficient supply and extract ventilation for separate premises.

EC motors with low energy consumption.Low-noise operation.Simple mounting.

Made of high-quality polymer coated steel, internally lined with heatand sound insulation of mineral wool, cellular synthetic rubber or other materials.Built-in preheater and reheater modifications available for cold climate conditions.

High efficient electronically commutated motors with external motor and impeller with forward curved blades. Such motors are the most state-of-the-art energy saving solution.EC motors are featured with high performance and total speed controllable range. High efficiency reaching 90 % is the premium advantage of the electronically commutated motors.

Exhaust cassette filter: ISO Coarse >60 % (G4).Supply cassette filter: ISO ePM1 60 % (F7).

The CIVIC EC LB… S21 V.2 units are equipped with an integrated automation system.The S21 controller allows integrating the unit into the BMS (Building Management System).The unit can be controlled by the Blauberg Home mobile application via Wi-Fi.

The units are equipped with a bypass. The bypass damper opens for free cooling ventilation mode in summer.

The automatic supply and extract air dampers are used to prevent uncontrollable air draughts during the unit standstill.

PREHEATING

CIVIC EC LBE V.2 and CIVIC EC LBE2 V.2 units are equipped with an electric preheater which protects the heat exchanger from freezing.

REHEATING

CIVIC EC LBE2 V.2 units feature an electric reheater to raise the supply air temperature.

The CIVIC EC LB V.2 unit has a counter-flow heat exchanger made of polystyrene.

• In cold season the heat energy of the extract air flow is absorbed by intake air flow, thus decreasing the heat losses caused by ventilation. Condensate generated during heat recovery is collected in a drain pan and removed to the sewage system.
• In warm season the heat of the outdoor air is absorbed by extract air flow. This way the supply air temperature decreases and heat recovery reduces operation loads for the air conditioner.

The CIVIC EC LB... -E V.2 unit is equipped with a counter-flow heat exchanger made of enthalpy membrane.

• In cold season the heat and moisture of the extract air are absorbed by supply air through the enthalpy membrane, thus decreasing the heat losses caused by ventilation.
• In warm season the heat and humidity of the outdoor air is absorbed by extract air flow through the enthalpy membrane. This way the supply air temperature and humidity decreases and heat recovery reduces operation loads for the air conditioner.

Cold outside air flows through the filters and heat exchanger and is moved to the room with a supply centrifugal fan.

Warm polluted air from the premise flows through the filter and the heat exchanger and is exhausted outside with an extract centrifugal fan through an air duct in the wall.
