The fluid ice slurry crystals are very small, smooth and round, and they enter every corner of the product to be cooled. This allows for fastest heat transfer, immediate and uniform cooling of the product and prevents the formation of potentially harmful bacteria, enzyme reaction and discoloration. Liquid ice slurry maintains peak product freshness for longer periods. The refrigeration and heat exchange capacity is strong, the reliability is high, and it is used as the condenser in the fluid ice slurry system.
