ebm-papst Mulfingen GmbH & Co. KG – construction of new energy-efficient production plant in Hollenbach.

At the end of 2007, ebm-papst Mulfingen GmbH & Co. KG completed construction of a new production plant in Hollenbach. The plant is 13,600 m² and consists of five separate building units: Production, turnery, administration with canteen and goods in and out. During construction of the new plant, the concept was to cover the industrial building’s entire heat requirement of around 750,000 kWh per year by optimally using waste heat generated in the production process. A large proportion of the heat is generated from lathes, robots and compressors.

Due to the regulated displacement ventilation, the air under the roof of the hall is kept at a temperature that can be used to heat adjoining building parts. Excess heat is stored in an 11,000 hl sprinkler container. This also serves as a heat sink for the heat pump. The stored heat is used efficiently to heat the remainder of the building. If the external air temperature rises above 24 °C, the building can be cooled using the heat pump, if required. Electricity consumption for the cooling system, compared to a conventional system, has been reduced by 19 percent from 83,300 kWh to 67,750 kWh thanks to the use of energy-saving technology.

Assessment
ebm-papst Mulfingen GmbH & Co. KG, has always been committed to energy efficiency, both in production and administration, and consistently allows for such measures when implementing new projects. This holistic approach is worth particular mention, as is the fact that the system layouts are oriented towards actual energy demand, for example with the ventilation and air conditioning systems.

Its intended use was already taken into account as the building was being designed, meaning that a solution was found in which available thermal load could be used to cover the heat requirement for the entire building. The
building is now heated entirely from the waste heat generated during production. The most up-to-date and energy-efficient technologies were taken into account when selecting components. The project can be transferred easily to other manufacturing companies with large internal thermal loads inside production halls.
