Auto-Defrost Vertical Spiral Seafood Tunnel Evaporator

Overview

Details

Material & Construction Versatility

The CJS unit offers flexible material options: Stainless Steel evaporator tubes (304/316), titanium, aluminum, or copper tubes, paired with 0.2~0.4mm Aluminum evaporator (aluminum-magnesium alloy) fins. The casing is available in titanium or stainless steel 304/316, with integrated corrosion protection and reinforced internal structures. Aerospace-grade fasteners ensure stability during high-velocity airflow operations.

Freezing Performance & Refrigeration

As a high-performance fast freezer evaporators system, it covers a cooling capacity range of 10~300 kW, compatible with HFC, NH₃, and CO₂ refrigerants. Its in-line geometry and vertical air direction generate concentrated high-velocity jets, with customizable fin distances (16-8, 18-9, 20-10, up to 40-20-10 mm, or custom). Centrifugal fans minimize pressure drop, while multi-mode defrosting (electric, hot gas, glycol, brine, water, ADF) ensures continuous operation.

Design & Compliance

The unit features a low-profile, wide-width design for seamless integration with impingement tunnels. It meets global hygiene standards with smooth surfaces and radius corners, supporting food safety compliance. Customizable intake configurations (plenum-style or flat-panel) adapt to diverse production layouts, while CE certification enables worldwide deployment.
