Weinreich-temper-devices mark themselves through central placings in temper-zones in common base frames with central cooling-water influx, and efflux lines as well as a central connection for separate water feeds. For machine maintenance an optional reserve can be provided or switchable spare devices via 3-way-valves in the consumer circuit. Furthermore, it is possible to assemble the single-temperature controllers for removable rails. The control of the plant can be carried out on the individual zones, a central control cabinet or externally via various control connections such as Profibus, Profinet or others. Expand can these systems with dessert facilities and water-treatment-plants.
