Motorhomes are in vogue, and there are a wide variety of mobile options for individual travel. One of the most luxurious is the recreational vehicle (RV) from various providers in the USA. With their elegant interiors, exclusive exteriors and powerful engines, RVs in this segment have developed into five-star hotels. Neither loudly humming air conditioners nor other technical systems operated by the power of compressors, such as the air suspension, door opening and closing or sanitary systems, fit into the picture. During the journey, the additional noise caused by these consumers is not yet disturbing because the compressor connected to the engine then provides the compressed air. But once stopped, travelers want to have their peace and quiet in the truest sense of the word. In this case, two additional compressors take over the task of ensuring a comfortable living environment when the vehicle is parked. In detail, the problem with the air supply system for the suspension, doors and toilets was the fastenings of the respective compressors. Mounted in one of the technical and supply areas underneath the motorhome, they transmitted the vibrations to the body. This led to clearly noticeable and audible vibrations that the owner did not want to tolerate, especially since the two smaller compressors run alternately at intervals of 15 to 30 minutes, depending on air consumption, which proved intolerable, especially at night.

Professional experience an advantage
Peter van Dijk, successor to the founding generation and senior manager of the Dutch company Dijko Ovens B.V. from Tilburg, felt compelled to act. As a mechanical engineer and expert in the automation and electronic control of oven systems with integrated vacuum and deep-freezing for large bakeries, neither air-conditioning technology nor pneumatic systems and compressors were books with seven seals for him. So he set out on the Internet to find industrially proven components for isolating vibrations. After a few clicks, he came across the pages of ACE Stoßdämpfer GmbH, www.ace-ace.de, which belongs to the Stabilus Group. Thereby, he noticed that the company from the Rhineland, in addition to products from the fields of damping technology, speed regulation and safety products, also has a large number of solutions for vibration control.

This market segment is of increasing importance for ACE, since vibration-isolating panels, vibration dampers and air springs can be used to meet stringent requirements for employee protection, including noise emissions. At ACE, the vibration damper sector alone consists of eleven different product families. Summarized under the collective term rubber-metal isolators, these components enable a wide range of applications. They isolate disturbing shocks and vibrations of machines and motors to such an extent that the working conditions for people and the environment are significantly improved. In the field of measurement technology, for example, it is often only through their use that usable results are obtained. Whether levelable or robust machine feet, pot elements, vibration-isolating connecting elements or quick-fixing elements, all ACE vibration dampers are universally applicable and represent ideal solutions for the majority of vibration problems known in industrial applications. The fact that the internationally known service of ACE also helps with individual projects like the one of Peter van Dijk is shown by the design for the calming of the compressors of the motorhome with the help of the free calculation tool, which can be found at this internet address:
