Various companies specialise in buying and selling technical equipment from industrial and other large buildings. For demolition and renovation projects, it is therefore useful to check whether large installations such as ventilation units or chillers can be reclaimed. Some dealers also offer smaller technical equipment, such as air conditioners. These elements can be interesting and cheap alternatives for new projects.
All this equipment has the advantage that it is usually equipped with a sign, which makes it easy to identify the model and its main technical characteristics. In some cases, these installations have a maintenance book with interesting information about their maintenance. Sometimes they are even covered by a maintenance contract, which may be "moved" together with the equipment to another building.
