Blauberg KOMFORT Roto EC LE 700-3.3 S17
- Capacity diagram
- Designation key
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, 250 or 315 mm air ducts. KOMFORT Roto EC LE/LW 2000 are designed for connection to 500x300 mm rectangular air ducts.DESIGN
KOMFORT Roto EC LE – model with electric heater. KOMFORT Roto EC LW – model with water heater. The casing is made of double-skinned aluzinc panels, internally filled with 20–25 mm mineral wool layer for heat- and sound-insulation. The casing has mounting brackets with anti-vibration rubber mounts for easy installation. The spigots are located at the sides of the unit and are equipped with rubber seals for airtight connection to the air ducts. The hinged side panels ensure easy access to the internals for service works including cleaning, filter replacement, etc.
The unit is equipped with high-efficient external rotor EC motors and centrifugal impellers with backward curved blades. EC motors have the best power consumption to air flow 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.AIR FILTRATION
The built-in G4 supply filter and G4 extract filter provide air filtration.
The unit has a high-efficient rotary aluminium heat exchanger. The rotary regenerator is a short, rotating cylinder, filled with corrugated aluminium sheet layers. The air streams flow through them. The band layers of the heat regenerator first come in contact with the supply and then with extract air flows. Therefore the band is alternatively warmed up and cooled down and the extract air heat and humidity are transferred to the cold intake air. This way heat recovery reduces heat losses in the cold season and reduces operation load for air conditioner in the warm season. The advantages of the rotary regenerator as compared to the plate heat exchangers include no condensate generation, maintaining comfort air humidity and high freeze resistance.
The unit can be installed on the floor, suspended to the ceiling or fixed to the wall by means of mounting brackets. The correct mounted unit must provide condensate collecting and drainage and free access to the hinged side panel for servicing and filter replacement. Access on the left side.
The integrated heater is activated to warm up supply air flow if set indoor air temperature may not be reached by means of heat recovery only. KOMFORT Roto EC LE are equipped with an electric heater for operation at low outside temperatures.
KOMFORT Roto EC LW are equipped with a water (glycol) heater for operation at low outside temperatures.
KOMFORT Roto EC LE…S17 and KOMFORT Roto EC LW…S17 are equipped with the th-Tune control panel.
