The FIC ageing tank is necessary to keep the ice-cream mix at 4°C. It has a slow stirrer and uses cold water or freon by request as the refrigerant (if freon is used, the refrigerating unit can also be supplied). The refrigerating fluid feeds the PILLOW PLATE exchanger which is integrated into the tank. The standard capacity varies from 300 litres to 12,000 litres.
The tank has an electronic control and can be supplied in either an open or closed version.
