Contracting for 300 logistics centres

deZem system as the information base for specialised contractors

A contracting provider uses the deZem system for the technical supervision and energy management of 300 logistics centres as well as for other successful contracting projects. Within the scope of a contract covering several decades, deZem acts "in the background" as a full service provider for data acquisition and processing, i.e. for installation, system setup and full maintenance of the software and hardware. The system was fully rolled out in 2013 within a few months, well below the promised time, and has been running without problems in close cooperation with the contractor ever since.
