Refrigeration specialist Güntner relies on BAUER for its testing needs

In the Güntner Group’s 80 years of history, the company has developed into a global leader in ventilation and refrigeration technology. In this sector of industry environmental protection and saving resources have moved into a particularly important role in recent years, inspiring the company to develop a heat exchanger which operates mainly with CO2 in a closed cycle instead of the environmentally harmful coolants used in conventional heat exchangers. Because these heat exchangers must be absolutely leak-tight, they undergo dry-air testing at pressures of up to 180 bar after production.  

Continuous availability of high-purity testing air is essential to ensure production operations run smoothly. As compressor systems by BAUER KOMPRESSOREN are synonymous with reliability in continuous operation, Güntner decided to switch their compressor supplier. After completing successful projects with BAUER in Indonesia and Hungary, the company once again turned to the Munich-based high-pressure specialists when choosing a system for its new plant in Sibiu/Romania. Three BAUER GROUP companies from Austria, France and Munich joined forcesin a cross-border partnership and designed a customized system for Güntner’s new mega-factory. They also brought a unique design concept to life: vast planters packed with greenery transform the production facilities into something resembling botanic gardens, and create a healthy climate and excellent working conditions. BAUER’s innovative compression concept was the perfect fit for this design. Four powerful VERTICUS compressors produce compressed air and store it in 12 cylinders, each with capacity of 80 litres. Each compressor is equipped with a B-KOOL refrigeration dryer for outstandingly economical operation. Four modified FCC control units designed by BAUER France then measure the highly compressed air for each test cycle to high precision levels. Austrian company BAUER POSEIDON KOMPRESSOREN was the project lead in the engineering and design of the system concept. Further projects are in the development stage.
