For variable flow rate and different usage times, the surface key has become obsolete.

Ventilation costs are allocated according to consumption

For many years, it has been customary to distribute ventilation costs of air handling systems based on the floor area, provided multiple users share a common air handling system.

In medium and large industrial complexes/buildings, large volumes of air are moved. Their verification is usually only car…

To give the lower parts of arch printing machines in the Würzburg plant a highly fine finish, KBA acquired a DIXI 270 machining center from the Swiss manufacturer DMG Mori in 2015. (Source: Nerling Systemräume GmbH)

In order for the machine to maintain the required accuracy values of ± 10 µm, a temperature of 22 °C ± 0.2 K/h must be maintained in the machine room. To ensure these climatic conditions, KBA commissioned Nerling System Rooms GmbH to set up a precision manufacturing room with a pre-temperature room. (Source: Nerling System Rooms GmbH)

The system room experts already established a Class 2 measurement room at KBA in 2006, which was directly connected to the machine room. (Source: Nerling Systemräume GmbH)

Overall, this resulted in a U-shaped system room setup consisting of the climate room (right in the background), its pre-temperature room (center of the image), the measurement room, and its pre-temperature room (left in the background). (Source: Nerling Systemräume GmbH)

The room system consists of a steel structure that serves as the load-bearing framework for the ceiling and the on-site 12.5-ton crane. (Source: Nerling Systemräume GmbH)

Since March 2015, the two new rooms have been successfully used. In addition, the lower parts of the arch pressing machines are also pre-fabricated outside the pre-tempering room on a DMG machine. (Source: Nerling SystemrÃ¤ume GmbH)

Then they are brought into the pre-temperature room on a lightweight rail system suitable for weights up to 8 tons.

There they are stored for 24 hours at 22°C until the parts have also reached this temperature. (Source: Nerling Systemräume GmbH)

There they are stored at 22 °C for 24 hours until the parts have also reached this temperature. (Source: Nerling Systemräume GmbH)

According to the First In – First Out principle, the parts are supplied to the DIXI 270 and machined with an accuracy of ± 10 µm. (Source: Nerling Systemräume GmbH)

Finally, the parts are returned to the tempering area and from there to the pre-chamber of the measurement room. (Source: Nerling Systemräume GmbH)

Measuring represents the final processing step.

Modular cleanroom systems

The CleanMediCell® cleanroom systems from SCHILLING ENGINEERING have been specifically developed for the demanding areas of product protection in the medical sector. For controlled production of medical components or pharmaceutical packaging systems, for example, injection molding or hollow body blo…

In the CleanCell® cleanroom of ISO Class 6, semiconductors for optical components are measured, assembled, and later packaged.

The technicians enter the cleanroom through an airlock and put on cleanroom-compatible clothing that releases only a few particles.

The 12 m² large material lock achieves ISO Class 7 and is separated from the cleanroom by quick-operating roller shutters.
