Tunnel Cooler

The Hermis tunnel cooler is designed for cooling various liquid products after the hot filling and pasteurizing process has been completed. Once they are cooled beverages are poured into a container and capped prior to final labeling and packing. Made of high quality stainless steel, tunnel coolers ensure that temperatures are controlled as the liquid cools down in the tunnel. They also ensure that the color, taste, smell, and texture of products being processed and packed are not altered. Determining the right type and configuration of tunnel cooler requires careful analysis of the products to be processed.
