The LX series is a precision-engineered evaporator unit and a core component of industrial spiral quick freezers, emerging as a reliable fast freezer evaporators solution for large-scale food freezing. Specifically designed as an evaporator for spiral quick freezer, it excels in ultra-low temperature environments (down to -40℃) and is fully compatible with ammonia (NH₃) refrigerants—offering high cooling capacity in a space-saving footprint. With CFD-validated airflow management and food-grade materials like Stainless Steel evaporator and Aluminum evaporator components, it prevents product displacement and minimizes weight loss, making it ideal for IQF lines, seafood spiral freezing, and bakery product processing.
The LX series boasts a cooling capacity range of 10–350 kW, catering to high-volume industrial needs. Its material options prioritize durability and efficiency: Stainless Steel evaporator tubes (304/316 grades) for ammonia compatibility and corrosion resistance, paired with Aluminum evaporator fins (0.2–0.4mm thickness) or epoxy-coated fins for enhanced heat transfer and hygiene. Fin spacing is customizable (16-8 mm to 40-20-10 mm) to match specific product freezing requirements.
Airflow is optimized via CFD (Computational Fluid Dynamics) validation, ensuring balanced face velocities (4.12–4.16 m/s) that maximize heat transfer without displacing delicate products. The unit supports horizontal air direction and multiple defrosting methods (electric, hot gas, glycol, water, brine, ADF). Equipped with vibration-dampened axial fans, it operates with minimal noise while maintaining stable performance. The evaporating temperature reaches -40℃, making it compatible with blast freezer systems for deep-freezing applications.
