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, 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.

 

FANS

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.

HEAT RECOVERY

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.

MOUNTING

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.

  HEATER

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.

  • Smooth electric heater output control ensures automatic maintenance of supply air temperature.
  • For overheating protection the electro heater is equipped with two built-in thermal switches: with +60 °C operating temperature, automatic restart, and with +90 °C operating temperature, manual restart.

KOMFORT Roto EC LW are equipped with a water (glycol) heater for operation at low outside temperatures.

  • Smooth water heater control ensures automatic maintenance of supply air temperature.
  • The air temperature sensor downstream of the heater and the return water temperature sensor are used for freezing protection of the water heater.
  • Water heaters are designed for operation with maximum operating pressure of 1 MPa (10 bar) and maximum heat medium operating temperature +95 °C.
  • The spigots of water heater are located on service panel side.
