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.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eIndustrial Cooling Tunnel Parameter\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMachine Model: ZS-CT3\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003ePower Supply: 3-Phase, 380V, 10 HP\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eInput Power: 8.5 kW\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCooling Capacity: 28,000 kcal\/h\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eEvaporator Airflow: 9,000 m³\/h\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCondenser Airflow: 18,000 m³\/h\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eConveyor System: 11-Line Multi-Pass Recirculating Conveyor, 11 * 3 m\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMinimum Cooling Temperature: -18°C\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMachine Body Material: SUS304 Stainless Steel\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMachine Dimensions: Approx. 4080 × 1863 × 1696 mm (L × W × H)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003e*Specifications are for reference only and may vary by your product.

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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does the 11-line recirculating conveyor work?\u003c\/strong\u003e\u003cbr\u003eProducts 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the ZS-CT3 a freezing tunnel?\u003c\/strong\u003e\u003cbr\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the cooling tunnel require compressed air?\u003c\/strong\u003e\u003cbr\u003eNo. Cooling runs through refrigerated air circulation only — no compressed air supply or compressed air line required in the installation layout.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the cooling capacity of the machine?\u003c\/strong\u003e\u003cbr\u003eCooling 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan the cooling temperature and conveyor speed be adjusted?\u003c\/strong\u003e\u003cbr\u003eYes. 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat material is the machine body made of?\u003c\/strong\u003e\u003cbr\u003eSUS304 stainless steel throughout.

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.\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"ZONESUN","offers":[{"title":"ZS-CT3","offer_id":48599559340273,"sku":null,"price":25799.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1538\/6957\/files\/ZS-CT3-industrial-cooling-tunnel.jpg?v=1787018341","url":"https:\/\/www.zonesuntech.com\/products\/zonesun-zs-ct3-automatic-conveyor-industrial-cooling-tunnel-machine-for-wax-lip-balm-filling-production-line","provider":"ZONESUN Technology Limited | Packing Machine Manufacturer","version":"1.0","type":"link"}
