Description
FEATURES

Air handling units for efficient supply and exhaust ventilation in flats, houses, cottages and other buildings. Used to create controlled energy-saving ventilation systems. The heat recovery technology is used to minimize ventilation heat losses. Control of air exchange for creating comfortable indoor microclimate. Compatible with round Ø 160, 200 or 250 mm air ducts.

FANS

High-efficient external rotor EC motors and centrifugal impellers are used for air supply and exhaust. The forward curved blades in KOMFORT EC LB(E) 300/LB(E) 400 provide permanent air flow. The KOMFORT EC LB(E) 700 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 high-efficient ventilation. EC motors are featured with high performance, low noise level and totally controllable speed range. The impellers are dynamically balanced.

 

DESIGN

The casing is made of double-skinned aluzinc panels, internally filled with mineral wool layer 40 mm for heat- and sound-insulation. The casing has mounting brackets with anti-vibration rubber mounts for easy installation. The unit is equipped with service hatches on the side panels for easy maintenance of filters. This design enables the left-hand and right-hand installation of the unit. The spigots are located at the sides of the unit and are equipped with rubber seals for airtight connection to the air ducts.

HEAT RECOVERY

The KOMFORT EC LB(E)… unit is equipped with a plate counter-flow polystyrene heat exchanger for heat recovery. The unit condensate is collected and drained to the drain pan under the heat exchanger.The KOMFORT EC LB(E)…-E unit is equipped with an enthalpy plate counter-flow heat exchanger for energy (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.

AIR FILTRATION

Two built-in G4 and F7 filters provide efficient supply air filtration. The G4 filter is used for extract air filtration.

AIR HEATER

The KOMFORT EC LBE S21 units are equipped with an electric heater for additional heating of supply air downstream of the heat exchanger. The KOMFORT EC LB S21 units are not equipped with built-in heaters but both a preheater and a reheater can be purchased separately.

  BYPASS

The KOMFORT EC LB(E) S21 model is equipped with a bypass which is automatically opened in summer if there is a need to cool down the ventilated area with cool intake air. If the unit is equipped with an electric heater, the bypass is used for freeze protection of the heat exchanger.

MOUNTING

Mounting on floor or ceiling with fixing brackets. The correct mounted unit must provide condensate collecting and drainage as well as access to service mounting and filter replacement.

CONTROL AND AUTOMATION

KOMFORT EC LB… S21 units are equipped with an integrated automation system. The remote control panel is not included in the delivery set (purchased separately). The S21 controller allows integrating the unit into the Smart Home system or BMS (Building Management System). The unit can be controlled via the Blauberg AHU mobile application via Wi-Fi.
