Tailor-made system solutions Air handling units for all applications The requirements on a ventilation system are not always the same. In many applications, all that is required, is a straightforward exchange of air, whereas in other applications the requirements can be very exacting, with regard to temperature, humidity and purity of the air. Rosenberg air handling units in the Airbox series have a modular design and can be individually configured. In this way, the appropriate solution can be assembled using a kind of modular principle for each application, in a quick and straightforward procedure....

rosenberg Airbox air handling units in modular construction (series A20, S40, S60, T60) The units consist of a framework structure with double-walled panels, that have acoustic and thermal insulation. The individual modules for the filter, fan, heater, cooler, heat recovery, acoustic insulation as well as the frame materials, are assembled flexibly according to the customers' requirements. Frameless Airbox air handling units (F40) The F40 series is produced in a frameless design. The panels are screwed together from the outside, which means the units have a smooth surface on the inside and will...

Energy efficiency Energy efficiency parameters of air handling units: The main factors which, are important for the energy efficiency of an air handling unit, are the air velocity in the profile unit face, as well as the electric power consumption of the fan, which is dependent on the air volume and pressure increase. In a combined air handling unit with heat recovery (HRU), the efficiency and pressure loss of the heat recovery must also be taken into account. We work in accordance with the statutory requirements of the German Energy Saving Ordnance (EnEV), as well as the requirements of the...

The units have a frame, made from hollow aluminium profile with two chambers, that are joined together using corner connectors, made from fibreglass reinforced polyamide. In order to ensure that the sidewalls are screwed together evenly, the profile is equipped with a guide groove. The 20 mm thick casing panels are double skinned. Up to size 08Q, the inside sheet is 0.75 mm thick, while the outside sheet is made from 1.0 mm galvanised steel. Coatings (standard RAL 7035) stainless steel (AlSl 304), or aluminium panelling (AlMg3) are available on request. The glass wool mats inserted between the...

Panel connection The panels for the Airbox A20 are screwed onto the aluminium frame profile, using countersunk tapped screws M6. The inside sheet of the panel is pressed against the frame profile by the outside sheet of the panel in this case. The necessary air leak tightness is achieved by the sealing strip between the inside sheet of the panel and the frame profile. Deformation of the outside sheet of the panel at the screw connection points means, that the countersunk screws form a level surface with the outside skin of the unit. Module connection: Special module connectors made from aluminium...

Casing design: Units in the F40 series have a frameless construction. The Air-box F40 is a low-cost alternative to the S40 series, with small sizes up to a unit size 13Q (outside dimension 1340 x 1340 mm). All panels in the F40 series are double skinned, with an inside sheet, outside sheet and insulation in between. The insulation thickness of the side and top panels is 40 mm. The bottom panel of flat units with operation from underneath is also fitted with 40 mm thick insulation. In all other variants, the insulation thickness of the bottom panel is 60 mm. The inner surface of the unit is completely...

Panel connection: The panels of the F40 series are designed to be offset in relation to one another at their connection points. They are screwed on from the outside at opposite sides in each case along the outside edges, meaning that a highly stable connection is achieved. The screws are located completely within the panel in order to provide the best possible thermal and visual properties. The openings in the outside sheet required for the screw connection on the inside are tightly sealed with UV-resistant plastic caps. Module connection: Gusset plates are mounted on the casing corners at the...
