RoofLine roof ventilation unit
Three main parts
The unit consists of three main parts, an outdoor unit, a roof frame and an indoor unit.
)
Outdoor unit
Roof frame
Indoor unit
Outdoor unit
High-performance casing
Weatherproof casing made of corrosion-resistant aluminum alloy (AlMg3), featuring double-shell wall panels with 50 mm thick non-combustible mineral fiber insulation per DIN 1643.
)
Air filter
Outdoor and extract air filters are equipped with highquality standardised bag filter inserts of filter quality M5 (ePM10 50%), optionally up to F7 (ePM1 60%).
The air filters can easily be maintained from the roof.
Air damper
Air dampers with counter-coupled hollow blades for outdoor air, exhaust air, recirculating air and plate heat exchanger bypass.
Sound attenuator
For the operation in very noise-sensitive areas, units with sound absorber at the exhaust air side are available; sound absorbers for supply air incorporated in the transition duct piece are also possible.
Roof frame
The scope of supply includes roof frame designs for flat roofs, sloped roofs and double sloped roofs, also custom made to meet constructional requirements.
Heat recovery
Counterflow plate heat exchanger made of completely smooth, dirtresistant, crosswise arranged aluminium plates. The heat recovery block can be dismantled for maintenance, two condensate drip trays, safe drainage of condensate through ready-fitted siphons. Integrated bypass for bypassing and power control of the heat recovery unit. Anti-freeze protection and defrost monitoring.
Fans
High-performance radial fan with backward-curved blades and flow-optimized inlet nozzle for high efficiency. Statically and dynamically balanced (DIN/ISO 1940, G 6.3), directly driven by an electronically commutated external rotor motor with integrated electronics.
Includes fault relay, locked-rotor protection, phase failure detection, soft start, undervoltage and overtemperature protection, and short-circuit safety.
Delivered as a complete unit with impeller, motor, and inlet nozzle.
Roof frame
Waterproof integration
The flat roof frame is made of corrosion-resistant AlMg3 aluminium with 50 mm thick interior insulation. It is designed for the installation of the outdoor unit on flat roofs and is suitable for all roof constructions. Designed to be incorporated into the roofing in a fully waterproof manner.
)
Indoor unit
No ductwork required
The indoor unit features a frameless aluminium casing filled with 35 mm mineral wool insulation. Reliable and precise operation is ensured by Siemens control technology, while a condensate pump is available as an optional accessory.
)
BURE diffuser
Adjustable geometry diffuser suitable for both heating and cooling applications, with the airflow pattern automatically adjusted by an electric actuator. BURE is made of robust, powder-coated steel and ensures low maintenance requirements and a long service life.
Cooling coil
Droplet eliminator
Heating coil
Construction
RoofLine roof ventilation units are designed for peripheral ventilation with heat recovery, heating and cooling. They consist of an outdoor unit, a roof frame and an indoor unit, and are ideal for exhibition halls, industrial buildings, gyms, storage facilities and indoor sporting facilities.
Aluminium thermal break profiles
Compact, lightweight sea water resistant (AlMg3) casing
Flexible design of indoor part according to customer requirements
Large inspection doors for easy maintenance
For building retrofitting and different roof designs
No duct system necessary
Outdoor unit
Weather-proof casing made of corrosion-resistant aluminium alloy AlMg3, double-shell wall panels with intermediate insulation made of non-flammable mineral fibre boards according to DIN 1643 with an insulation thickness of 50 mm.
Revision doors with exterior hinges and handles, with gaskets for reliable sealing even at high wind pressures. Suction and exhaust openings with driving-rain-proof rain hoods made of aluminium and protective bird screens.
The air heater (air cooler) is installed inside to be protected against frost. No pipes on the roof which are subjected to frost.
The casing of the outdoor unit and the indoor unit can be supplied in RAL colours (additional charge).
Available for units without integrated control for additional charge: lockable repair switch for intake and outlet air fan mounted on the unit, all electrical connections wired on central terminal box.
Roof frame
Roof frame made of aluminium AlMg3, for the installation of the RoofLine outdoor unit. The roof frame is incorporated in the roofing in a water-proof way. The design of the roof frame must be negotiated in the order process; later modifications are not possible. For buildings with raised crane tracks where the indoor part would extend downwards too much, the height of the roof frame can be increased so that most of the indoor part reaches into the roof.
Indoor unit
Direct air supply and air extraction without ducts, with possibility of installation of water heating coil, water cooling coil or reversible coil (heating / cooling), self-supporting casing, air distribution element (RotaVent - rotating nozzle and/or swirl diffuser), extract air grille or design for duct connection.
Control
Integrated control system with master/slave control
Easy integration of control system into building management system via Modbus, EXOline & TCP/IP
Selection software
Capacity and technical data are calculated by the airCalc++ software. Within a few minutes, it's possible to get the preferred configuration of the units and accessories.
Optional
Sound attenuator for exhaust and supply air optional
Water heating coil, water cooling coil or reversible coil optional
