Marlen’s Medium Spiral Chillers are ideal for processors looking for a scalable solution that is fully welded, mechanical, and compact. Use as a standalone solution or build multiple lines with this industrial production machine. Our Medium Spiral Chillers deliver ultra-hygienic design features while maximizing production capacity in a compact design. This chiller’s horizontal airflow offers efficient freezing or chilling without the ongoing operational expense of cryogenics such as nitrogen gas. The chiller’s control system automatically adjusts to recipe setpoints including a signal for automatic defrost. Marlen Medium Spiral Chillers provide a reliable solution for targeting consistent product core temperatures, with optimal moisture retention, so you can yield those juicy, crispy, tender, and safely frozen or chilled-to-perfection results.
