A chiller is located on the container roof. After delivery of the container from the loading crane, this put directly in position and flanged on. All the waste heat from the container is dissipated through it. For this purpose, the chillers of the climatic chamber and the media conditioning as well as the cyclers are connected to a common cooling circuit. Both the cooling of the container itself and the heating are carried out by a self-sufficient air-conditioning split unit. This ensures that personnel and electronics can work in good conditions in both summer and winter. A fan provides a supply of fresh air.
