Rosenberg and Airtècnics have been supplying their products to the railway sector for years with fans for trains and also with air curtains for stations and hangars. This time, thanks to the reliability and quality of our products, a large railway manufacturer has requested Rosenberg's professionalism to install an air handling unit with air conditioning in its wagon factory in eastern Germany. This AHU is designed for supply and exhaust air with heat recovery.As the space for the AHU is very limited, the unit was built entirely as a monoblock on a base frame and the ...

The entry of insects into food industry and shops is considered a negative aspect because in contact with food products, they can transmit diseases. These diseases, known as "vector-borne", account for more than 17% of infectious diseases globally. How to combat this problem successfully? The least invasive way to prevent insect infestation is to restrict their access in buildings with air curtains, rather than eliminating them with electronic insect control devices, traps or pesticides, which can be harmful to humans and Earth. Aim of the study This study aims to demonstrate the ...

One of the most successful products for optimising air handling unit installations is the EC Fan Grid. These are EC fans mounted in a matrix that replace older, large fans (usually belt-driven) and thus achieve greater energy and economic savings. The special distribution of these EC Plugfan backward blade fans achieves the maximum adaptability in each project: one of the main characteristics of Airtècnics and Rosenberg. The latest example of a Rosenberg retrofit project is the replacement of a large belt-driven fan in a hospital ventilation system with several smaller EC ...

How does an EC motor work? The EC (electronically commutated) motor is a synchronous motor powered by an inverter with permanent magnets in an external rotor design. The stator is driven by electronic switches controlled by a microcontroller. The motor needs to be supplied with AC voltage and a DC voltage signal to operate.The mains voltage, namely the alternating current (AC), is rectified by the electronic commutation of the EC motor. A downstream inverter supplies the motor voltage via the direct current (DC) signal in accordance with the specified load. In contrast to the AC ...

Among the Airtècnics solutions is the renovation or incorporation of custom ventilation systems. Today we are dealing with a real case in Germany, in the Ruhr area, in the west of the German country, where an air handling unit has been installed in a large restaurant.    The model chosen by the restaurant was the Airbox F40 without frames. A very light weight was required, but it was essential that the sound values ​​were low. In addition, the units had to be very compact, because there was very limited installation space. The instalation is composed by two ...

Data centers produce a lot of heat, which is one of the problems they cause and one of the most important to eradicate. Energy-efficient EC fans help to reduce operating costs and are part of an economical and environmentally friendly cooling concept.    Most of the energy consumed by data processing centres goes into cooling and conditioning the environment surrounding these electronic devices. Data centres are spaces in which an organisation's information is stored and processed, and these spaces can be as large as a building, occupy basement rooms or be the size ...
