Together with the system specialist ONI, Bergi-Plast GmbH from Saxon Switzerland has implemented an integrated, optimized supply concept.

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 through single and multi-component injection moulding processes for the highest demands to the assembly of complex assemblies. In addition to the continuous expansion of Bergi-Plast's successful market position, the company also focuses on improving efficiency in energy and process technology and environmentally friendly production. One example of this is certification in the areas of energy management in accordance with DIN ISO 50001 and environmental management in accordance with DIN ISO 14001.

"As an energy-intensive company, it is clear to us that energy costs are becoming increasingly important and that competitiveness can only be maintained if we reduce consumption to a minimum," explains managing partner Ronny Epperlein. "We have therefore been actively dealing with this topic for years and are consistently focusing on clever and already successfully implemented savings concepts". For the new cooling system, those responsible once again brought the company ONI from Lindlar on board as a partner. "Their exemplary solutions have already convinced us impressively in the past," explains Epperlein.

The aim of the current project was to use energy with the highest possible efficiency in production processes and systems for the generation of cooling water, ventilation or compressed air. In addition, this should be available for a second time for energy network systems. For this purpose, a holistic supply concept with outstanding effective benefits was developed. In concrete terms, the ONI technicians set up a dual-circuit cooling system that, by using the outside air as a cooling energy supplier, ensures the lowest possible use of electricity for cooling machines and tools as well as for ventilation technology. In addition, the consistent use of free machine waste heat in all areas of the company means that primary energies for heating purposes can be dispensed with as far as possible.
