Stamped Sheet Metal from Kachtenhausen – Optimal Energy Utilization at Spilker GmbH.

The construction of the new Kachtenhausen plant provided the long-awaited opportunity for the long-established manufacturer Spilker to thoroughly review production processes and energy consumption based on years of experience at the Leopoldshöhe plant and to optimize them accordingly at the new location.

The concept developed and implemented by Redeker uses an industrial heat pump to raise the unusable low-temperature waste heat from the etching process to a temperature level suitable for heating the plant. Only after this utilization is the residual heat then cooled using highly efficient free coolers and, finally, power-controlled screw components, thus significantly reducing the energy-intensive use of the chillers. Three precision climate chambers with cooling, heating, humidifying, and dehumidifying functions guarantee the high manufacturing precision required in the milling process. The room temperature is regulated with an accuracy of 0.2 to a maximum of 0.5 K, and the relative humidity is controlled to +/- 5%. Air distribution is absolutely uniform and, above all, completely draft-free thanks to textile displacement ventilation ducts. The administration building and other production areas are cooled and heated by a highly efficient VRV system. Two ventilation systems with integrated heat recovery ensure excellent indoor air quality and make the facility "corona-safe".

The energy-efficient interaction of refrigeration, heating, air conditioning, and ventilation technology is managed by a DDC system control integrated into the Spilker LAN, including online access by Redeker Kältetechnik.
