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.

Overview of the unit series

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 S60 and T60 are equipped with a framework construction made from aluminium or galvanised, rolled steel profiles and aluminium cast corner connectors or plastic corner connectors. The double-skinned panels of Airbox S60 and T60 air handling units are 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).

Rosenberg offer a wide range of standard fans for a variety of applications and fans for OEM applications. All Rosenberg fans are equipped with direct driven external rotor motors which are manufactured in-house. The Rosenberg fans offer you fans with decisive advantages in comparison to conventional fans:

• extremely long service life
• compact design
• motor and impeller assembled in one unit
• the speed is 100% controllable (auto transformers ; controller)
• low start-up current
• Rosenberg fans are equipped with motor protection through thermal contacts as a standard feature
• The impellers are balanced on 2 levels according to DIN ISO 1940 (quality grade G2.5).

AC motors

The drive using an external rotor motor offers space-saving, compact and attractive design. The engine sits inside the impeller and is thus optimally cooled. For this reason, a 100%variable speed control can be guaranteed. V-belts, additional tension bars and motor mounting devices are not necessary. Only well-dimensioned ball-bearings, fitted on both sides and long-life lubricants are used. Both ball-bearing seats are ground to high precision in one work process to eliminate any vibration.

External rotor motors are also characterised by an extremely low start-up current. The drive motors correspond primarily to protection class IP54 according to DIN EN 60034-5. The winding insulation corresponds to the thermal class F. In addition, the winding has a standard moisture protection impregnation.

EC motors

The EC motors used are characterised by very high efficiency even at partial loads, and excellent control behaviour. They are easy to connect, individually preconfigured, compact in design and have a high power density. The implementation of additional functions (e.g. volumetric flow and pressure control) is possible. Rosenberg EC motors primarily meet protection class IP54; input voltage of 380V-480V (50/60Hz). Rosenberg EC motors are continuous speed controllable and have integrated motor protection.
