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. Both, in the high-tech area and for classic building technology, air handling units from Rosenberg deliver clean air at the right tempered room climate. Weather-proof and explosion-proof designs are possible, as well as TÜV certified hygiene variants. The units consist of a framework structure with double-skinned panels that have acoustic and thermal insulating properties. 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.

The F40 series is produced in a frameless design. The panels are screwed together from the outside so that the devices are smooth internal surfaces and are hence hygienically safe. The air handling units Airbox A20, S40, S60, T60 are equipped with a framework construction made from aluminium or galvanised, rolled steel profiles and aluminium cast corner connectors or plastic corner connectors. In the case of the Airbox A20, the double-skinned panels are insulated with non-combustible, sound and thermal insulating mineral wool. The Airbox S40, S60 and T60 air handling units are also filled with non-combustible, sound and heat insulating rock wool insulation. In addition to galvanised steel panels and the framework construction, it is also possible to select coated steel, aluminium and stainless steel versions in our range. For modules with smaller dimensions, the base frame is manufactured in various heights (100, 300, 500 mm) using galvanised, folded steel sheet. Larger modules have a welded base frame (primed or galvanised).

3 mm aluminium profile 1,5 mm galvanised steelor stainless steel 1,5 mm galvanised steel 1,5 mm aluminiumand thermally decoupled 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. air conditioning single unitIn a combined air handling unit with heat recovery (HRU), the efficiency and pressure loss of the heat recovery must also be taken into account.ac units for large windows We work in accordance with the statutory requirements of the German Energy Saving Ordnance (EnEV), as well as the requirements of the German AHU Manufactures Association (RLT) when selecting the parameters for air velocity, the electrical power consumption of the fans and the efficiency of heat recovery. home central air conditioner how it works

The criteria of the RLT energy efficiency label correspond to the standard DIN EN 13053 A1 (2011). This standard defines nine air velocity classes from V1 to V9, six heat recovery classes from H1 to H6 as well as six classes for the power consumption of fans from P1 to P6. The specific power consumption of a fan (SFP), installed in the air handling unit, is calculated as defined by the current DIN EN 13779. Air velocity class without thermal air treatment Air velocity class with air heating and / or heat recovery Air velocity class with additional functions Electric power consumption class Heat recovery classes (4,000 - 6,000 hours per year) > 1,6 to 1,8 > 1,8 to 2,0 > 2,0 to 2,2 > 2,2 to 2,5 > 2,5 to 2,8 > 2,8 to 3,2 > 3,2 to 3,6 The accuracy of the data output by our AHU selection software is regularly checked and certified by TÜV Süd, on behalf of the RLT association.
