Features

Compact ventilation unit with heat recovery for floor-standing installation indoors or outdoor installation, including control system, fully wired. Universal installation with outdoor air connection on the left or right possible. Built-in electric preheating register to protect the heat exchanger from freezing at very low outdoor air temperatures. For increased comfort temperature requirements, an electric or hot water reheating coil can be installed in the unit housing as an option. Housing: Consisting of robust and stable aluminium frame profiles, thermally optimised to minimise thermal bridges. Double-walled panels made of aluzinc sheet metal, insulated on all sides with 50 mm mineral wool for optimum heat and sound insulation, coated on the outside with a corrosion-resistant finish (class C4) (RAL 7047), galvanised on the inside. Housing classes according to DIN EN 1886: T2/TB2/D2, generous inspection openings on both sides of the unit for easy access to all unit components and optimum cleaning and maintenance options. The Eurovent-certified aluminium rotary heat exchanger (condensation rotor) is manufactured according to the latest production standards and guarantees the highest quality and high thermal efficiency. The heat exchanger is suitable for heat and cold recovery with additional moisture transfer capability and guarantees frost protection down to approx. -15 °C outside air temperature. Optimum hygiene is ensured by a sophisticated sealing system and a purge chamber included in the scope of delivery. An innovative drive belt ‘Power Belt’ also guarantees high wear resistance, a long service life and easy replacement. Fans: 2 direct-drive EC motors, class IE4 with very low SFP values, dynamically balanced and vibration-damped in the unit. Steplessly controllable via 0-10V signal. Plug connections on all electrical components to simplify maintenance work. Filters: Two large-area, pressure loss-optimised cassette filters are installed as standard (outdoor air ePM155% (F7) and exhaust air ePM10 50% (M5)). Use up to filter class ePM1 80% (F9) in the outside air and ePM1 55% (F7) in the exhaust air is optionally possible. In addition, a pre-filter of class ePM 10 50% (M5) can be used in the outside air directly in the unit. The filters are monitored by means of dynamic, volume flow-dependent pressure monitoring. Control: The ventilation unit is delivered ready for operation with a versatile control system. The control system is easy to maintain, located in a connection box on the side of the unit, factory-wired and function-tested. Two control elements (ECO and Touch) are available (required accessories). Control functions: Ventilation modes: constant volume CAV, constant pressure VAV (accessories required), constant speed CRPM in % or via weekly program. Automatic ventilation mode/ventilation on demand (VOD) via humidity, CO2 or VOC sensors. Up to 18 sensors can be connected per ventilation unit. Free cooling, active cooling via cooling register (cold water or DX). Temperature control, e.g. constant supply air, supply air controlled by outside temperature, room supply air cascade, etc. possible. Digital inputs for fire alarm and external switch (on/off). Digital output for collective fault signal. External fan control via two analogue 0-10V inputs (supply air and exhaust air fan separate). Connection to the building management system via BACnet IP or Modbus TCP possible. Commissioning wizard for quick and easy commissioning of the unit and the appropriate accessories.
