Bergi-Plast GmbH: Energy Costs Successfully Curbed
As an innovative manufacturer of high-quality plastic products, the company—with branches in Bad Gottleuba-Berggießhübel and Dohma—offers its customers a full range of services, from tool development and toolmaking to single- and multi-component injection molding processes designed to meet the highest standards, and the assembly of complex subassemblies.
In addition to continuously expanding its successful market position, Bergi-Plast also focuses on improving efficiency in energy and process technology and on environmentally friendly manufacturing. Evidence of this includes, for example, certification in the areas of energy management according to DIN ISO 50001 and environmental management according to DIN ISO 14001.
“We have therefore been proactively addressing this issue for years and consistently rely on smart energy-saving concepts that have already been successfully implemented.” For the new refrigeration system, the project managers once again brought ONI, based in Lindlar, on board as a partner. “Their exemplary solutions have already impressed us greatly in the past,” explains Epperlein.
Security through Availability
The goal of the current project was to utilize energy with the highest possible efficiency in production processes and systems for cooling water generation, ventilation, and compressed air production. Furthermore, this energy was intended to be made available a second time for integrated energy systems. To this end, a comprehensive supply concept with outstanding practical benefits was developed.
Specifically, ONI technicians installed a dual-circuit cooling system that uses outside air as a source of cooling energy, ensuring the lowest possible electricity consumption for cooling machines and tools as well as for ventilation. Furthermore, through the consistent use of free machine waste heat, the company can largely eliminate the need for primary energy sources for heating purposes across all areas of the facility.
