Within the framework of the BAFA-sponsored 'Energy consulting for medium-sized enterprises' (EBM), the entire Brendle GmbH & Co. KG in Dettingen/Erms was analysed under the aspect of energy efficiency. In the run-up, relevant data was collected by the company's employees and completed during the on-site visit by the consultants from OPTENDA (until April 2020 GILDEMEISTER energy efficiency GmbH), so that a detailed energy-related starting point was determined. In addition to the purchased energy quantities and costs, the recorded data includes performance data, operating hours and years of construction of the individual plants and machines. Furthermore, the current load curve from 2016 was processed and analysed in detail. The subsequent analysis focused on heat and compressed air generation and hall lighting.
Within the scope of the consulting services, a ventilation and air conditioning concept for the production halls was also drawn up for Brendle GmbH & Co. KG. Among other things, the waste heat of the air compressors can be used for this purpose via an adsorption system for the provision of cooling.
During the on-site inspection two energy meters were installed. The measuring devices record the electricity supply from the distribution network and the generation of the PV system. Thanks to the monitoring system, a regular recurrent load peak could be identified on the weekends. Closer examination of the reason for this was identified in the non-disconnected air compressors. Corresponding corrective measures could be initiated purposefully. In general, energy monitoring makes sense, as it allows valid and up-to-date energy data to be used. Optimization measures can be calculated much better by the monitoring and can be tracked after implementation.
Thanks to the energy consulting, several possibilities for energy savings were presented to Brendle GmbH & Co. KG and quantified with concrete calculations. The measures described can now be implemented step by step.
As a specialist in the field of precision turned and precision milled parts, Brendle GmbH & Co. KG supplies its customers with prototypes, special series and serial parts. In addition to mechanical and automotive engineering, the sectors supplied include the electrical industry as well as process engineering and medical companies. An example product of the company Brendle GmbH & Co. KG are the nozzles for sewer and ultra-high pressure cleaning.
OPTENDA, formerly GILDEMEISTER energy efficiency GmbH, headquartered in Stuttgart, offers its customers holistic and individual solutions in the areas of energy monitoring, energy management, optimization of the energy efficiency of buildings, technical systems and processes as well as the reduction of energy costs.
Very competent and friendly advice. Many hints and tips, which lead to significant savings when consistently implemented.
