We supply heat exchangers specifically designed as evaporators for industrial tunnel freezers with high cooling capacities. In these heat exchangers (approx. 100 to 1,000 kW each), the refrigerant extracts heat from the air to be cooled. The highest possible heat transfer helps preserve the quality of the product being frozen and also saves energy. At VDL Klima, this is in trusted hands, thanks to more than 100 years of knowledge and experience in heat transfer. In addition to preserving product quality during freezing, food safety also plays a leading role. After all, the air flowing through our heat exchangers comes into direct contact with the unpackaged food products. That is why we place a strong focus on a distinctive hygienic design and optimum cleanability. In addition to good design, craftsmanship and quality, our customers also praise us for the pleasant and close cooperation.

Tunnel freezers are designed to freeze a large continuous throughput of high-quality food products economically. Factors such as sequential defrosting, consistent quality of the frozen product, and maximum freezer reliability and availability all play an important role. These factors are also influenced by the correct configuration and design of the evaporators. That is why, in close collaboration with you, we determine the optimum solution, and our heat exchangers are specially designed for you so that they meet your specific requirements precisely.

Our specialists will be happy to provide further advice on your project or specific application.
