KOMFORT Ultra EC S2 300 Compact heat recovery air handling units Features Air flow: up to 300 m³/h 83 l/s Heat recovery efficiency: up to 79 % Air handling units for efficient supply and exhaust ventilation in flats, houses, cottages and other buildings. The heat recovery technology is used to minimize ventilation heat losses. Control of air exchange for creating com fortable indoor microclimate. Compatible with round ∅ 125 mm air ducts. The casing of KOMFORT Ultra EC S2 300 ... white is made of doubleskinned white painted metal panels, internally filled with 20 mm mineral wool layer for heat- and sound-insulation. The spigots are located at the top of the unit and are rubber sealed for airtight connection to the air ducts. The hinged panel of the casing ensures easy access to the unit internals for service works including cleaning, filter replacement, etc. COMPACT HEAT RECOVERY AIR HANDLING UNITS The unit is equipped with high-efficient external rotor EC motors and centrifugal impellers with forward curved blades. EC motors have the best power consumption to air flow ratio and meet the latest demands concerning energy saving and high-efficient venti lation. EC motors are featured with high performance, low noise level and totally controllable speed range. The impellers are dynamically balanced.
