The RM 4.2 is a multitube, multi-pass scraped-surface heat exchanger engineered to process viscous or heat-sensitive products that require extended thermal treatment. Its multi-pass configuration allows a longer residence time within a compact footprint, while the scraping system prevents fouling and maintains uniform heat exchange. Ideal for high-viscosity products, it ensures consistent performance and hygienic operation in demanding food and plant-based processing environments.
