The 100% aluminum evaporator for air blast freezing tunnels is specifically engineered for high-capacity, low-temperature refrigeration applications in the food processing and cold chain industries. Designed to operate with Freon R-507 refrigerant, this evaporator delivers 380–390 kW of cooling capacity at −35°C, ensuring rapid and uniform freezing performance in demanding industrial environments.
Air blast freezing tunnels require powerful and reliable evaporators to achieve fast temperature pull-down and uniform airflow across products. This evaporator is optimized for installation in continuous or batch air blast freezers, supporting high air velocities and stable low-temperature operation.
Its geometry, fin spacing, and tube layout are engineered to maximize heat transfer while maintaining controlled pressure drop, ensuring consistent freezing quality and high throughput.
The evaporator is manufactured entirely from aluminum, including tubes, fins, headers, and casing. This all-aluminum design offers several advantages:
Excellent thermal conductivity for efficient heat exchange
Lightweight structure, reducing installation load
High corrosion resistance in low-temperature and humid environments
Long service life with minimal maintenance requirements
The aluminum construction also improves system efficiency by enabling faster heat absorption from circulating air.
Designed specifically for R-507, a widely used low-temperature refrigerant in industrial freezing applications, the evaporator ensures stable evaporation performance at −35°C. Circuiting and internal flow design are optimized to support high refrigerant mass flow rates while maintaining uniform distribution and reliable oil return.
This compatibility ensures high efficiency, operational stability, and compliance with established industrial refrigeration practices.
With a cooling capacity of 380–390 kW at −35°C, this evaporator meets the requirements of large-scale air blast freezing tunnels used for:
Meat and poultry freezing
Seafood processing
Ready-to-eat and convenience food freezing
Bakery and dough freezing applications
The high capacity enables rapid freezing, minimizing product dehydration and preserving texture, color, and nutritional value.
The evaporator is designed to work with high-efficiency axial fans, ensuring uniform airflow across the entire heat exchange surface. Fin spacing is optimized to balance heat transfer efficiency and frost resistance.
The design supports both electric and hot gas defrost systems, ensuring reliable operation and quick defrost cycles under continuous low-temperature conditions.
