Process Freezing

Process freezing operations — IQF tunnels, spiral freezers, blast freeze rooms, and freeze-dryers — operate at -18°C to -40°C. At these temperatures, even small amounts of moisture cause massive frost and ice accumulation on evaporator coils, belts, and product surfaces. Defrost cycles become more frequent, dramatically reducing operational efficiency and throughput. In Tamil Nadu and Kerala's high-humidity tropical climate, ambient air infiltration during loading creates extreme frost events. Manual defrost during production shutdowns adds cost, energy waste, and microbiological risk. The solution is removing moisture from the air before it reaches cryogenic temperatures.
