ZONESUN ZS-CT3 Industrial Cooling Tunnel with Reciprocating Conveyor System
The ZONESUN ZS-CT3 is an industrial cooling tunnel designed for continuous cooling and solidification of products after processing. With a powerful cooling capacity of 28,000 Kcal/hr, it features an efficient piston compressor, a reciprocating conveyor system that extends cooling time without increasing floor space, and comprehensive protection devices for safe operation. The stainless steel construction ensures durability, hygiene, and easy maintenance, while the adjustable conveying system allows precise cooling time control. Ideal for chocolate, confectionery, bakery, beverage, wax, candle, and other food processing applications requiring reliable and uniform cooling.
Key Features
- Control Panel – Controls the cooling tunnel’s operating status and parameters, enabling start, stop, and adjustment of cooling and conveying functions for precise control and stable operation.
- Maintenance Access Door – Provides access to the inside of the cooling tunnel for cleaning, inspection, and maintenance. The sealed design helps prevent cold air leakage and improves refrigeration efficiency.
- Reciprocating Conveyor System – Extends the product travel distance and cooling time inside the tunnel through a back-and-forth conveying path, ensuring more uniform and sufficient cooling while saving floor space.
- Evaporator – Generates cold air through refrigerant circulation and heat exchange, providing stable cooling for fast and uniform product temperature reduction.
- Refrigerant Receiver – Stores and regulates liquid refrigerant to ensure a stable supply, reduce fluctuations, and improve the stability and efficiency of the refrigeration cycle.
- Condenser Fan – Enhances condenser heat dissipation by forcing airflow, helping refrigerant release heat and complete the condensation process for efficient and stable refrigeration performance.
Benefits
- High Cooling Capacity – Delivers 28,000 Kcal/hr of efficient cooling for rapid product temperature reduction.
- Extended Cooling Time – Reciprocating conveyor design prolongs product travel distance, ensuring thorough cooling without occupying extra floor space.
- Safe & Reliable – Multiple protection devices including high/low pressure switch, overload protection, phase reverse protector, and coil overheat protector for worry-free operation.
- Durable Construction – Stainless steel body provides excellent corrosion resistance, hygiene, and long service life in food processing environments.
- Easy Maintenance – Maintenance access doors and well-organized internal layout simplify cleaning and routine service tasks.

Component Details
Control Panel
Controls the cooling tunnel’s operating status and parameters, enabling start, stop, and adjustment of cooling temperature and conveying speed for precise and stable operation.
Reciprocating Conveyor System
Back-and-forth conveying path extends product travel distance and cooling time inside the tunnel, ensuring thorough and uniform cooling while minimizing the machine’s floor space footprint.
Evaporator
Generates cold air through refrigerant circulation and heat exchange, providing stable and uniform cooling airflow for fast product temperature reduction throughout the tunnel.
Piston Compressor
Efficient piston-type compressor delivers reliable 28,000 Kcal/hr cooling capacity with 0–100% capacity control for flexible adaptation to different production requirements.
Refrigerant Receiver & Condenser Fan
Refrigerant receiver stores and regulates liquid refrigerant for a stable supply, while the condenser fan forces airflow to enhance heat dissipation and maintain efficient refrigeration cycle performance.
Maintenance Access Door
Sealed access doors provide convenient entry to the tunnel interior for cleaning, inspection, and maintenance while preventing cold air leakage to maintain refrigeration efficiency.
Stainless Steel Construction & Protection Devices
Stainless steel body ensures hygiene and durability, while six built-in protection devices (high/low pressure switch, fusible plug, overload protection, coil overheat protector, auto temperature switch, phase reverse protector) guarantee safe, worry-free operation.
