ZONESUN ZS-CT3 industrial cooling tunnel cools products continuously through refrigerated air circulation and an 11-line recirculating conveyor system. Minimum cooling temperature reaches -18°C. The 11-line conveyor extends product travel path by recirculating within the tunnel footprint rather than running in a straight line. More passes mean longer residence time without a proportionally longer machine. Cold air circulates around products throughout the conveyor path. Uniform air distribution keeps cooling consistent across the full product cross-section. Cooling temperature and conveyor speed adjust at the control panel. Getting the combination right for a specific product requires knowing both the target exit temperature and how quickly the product sheds heat at the set cooling temperature. SUS304 stainless steel construction. Enclosed design. No compressed air required. The tunnel integrates inline with continuous production lines as one cooling stage in the sequence.

Machine Detail
The control panel allows operators to adjust key settings such as cooling temperature and conveyor speed. This helps control product residence time and cooling conditions inside the tunnel.
The air cooling fans continuously circulate refrigerated air around the products. This forced air circulation supports heat transfer while helping reduce water droplet condensation during cooling.
The conveyor guides products through 11 lines inside the cooling tunnel. The multi-pass path extends product residence time within the cooling zone, supporting more uniform cooling without requiring a longer tunnel.
The condenser removes heat from the refrigeration system to support continuous cooling inside the tunnel. It works with the refrigerated air circulation system to maintain the required cooling conditions.
SUS304 stainless steel construction throughout. Smooth stainless steel surfaces resist residue buildup between cleaning cycles.
FAQ of Industrial Cooling Tunnel
What is an industrial cooling tunnel?
A continuous cooling system that moves products through a refrigerated air circulation zone on a conveyor. Products enter at one temperature and exit at a lower one — how much lower depends on the cooling temperature set, conveyor speed, and how quickly the specific product sheds heat across its cross-section.
How does the 11-line recirculating conveyor work?
Products travel through 11 passes inside the tunnel rather than one straight run. More passes mean longer residence time in the cooling zone without requiring a proportionally longer machine footprint. For products that need extended cooling to reach a stable temperature before the next production stage, the pass count is what determines whether the tunnel is long enough.
Is the ZS-CT3 a freezing tunnel?
The minimum cooling temperature is -18°C, but whether a specific product reaches a frozen core at that set temperature depends on the product's thermal properties, dimensions, starting temperature, and conveyor speed. These variables need to be evaluated against the product and process requirements before confirming suitability for freezing applications.
Does the cooling tunnel require compressed air?
No. Cooling runs through refrigerated air circulation only — no compressed air supply or compressed air line required in the installation layout.
What is the cooling capacity of the machine?
Cooling capacity: 28,000 kcal/h. Evaporator airflow: 9,000 m³/h. Condenser airflow: 18,000 m³/h. Whether that capacity is sufficient for a specific product and production rate depends on the product's heat load — confirm against the product's starting temperature, mass per hour, and target exit temperature.
Can the cooling temperature and conveyor speed be adjusted?
Yes. Both adjust at the control panel. The two variables interact — slower conveyor speed increases residence time at a given temperature, faster speed reduces it. Adjusting one without accounting for the other changes the product's exit temperature.
What material is the machine body made of?
SUS304 stainless steel throughout. Enclosed structure keeps the cooling environment separated from the surrounding production area and simplifies cleaning between production runs.
What information is needed to confirm cooling performance for a product?
Product type and dimensions, initial temperature, target exit temperature, required cooling time, and production capacity in units or mass per hour. These parameters determine whether the tunnel's cooling capacity and conveyor configuration match the actual heat load the product generates — cooling performance can't be confirmed without them.
