Details

Refrigeration & Capacity Details

This blast freezer supports a wide range of refrigerants, including HFC, NH₃ (ammonia), CO₂, glycol, water, and brine, ensuring flexibility for different environmental and operational requirements. The evaporator unit boasts a robust capacity range of 15 ~ 250 kW, making it suitable for small to large-scale processing lines. Fin distances are customizable (12mm, 16-8mm, 18-9mm, up to 40-20-10mm) to optimize heat transfer efficiency based on specific applications.

Material & Structural Design

Constructed with food safety and durability in mind, the system offers multiple material options for critical components: Stainless Steel evaporator (304/316 grade) for corrosion resistance, Aluminum evaporator for lightweight efficiency, and additional choices like titanium, copper, and AlMg for specialized needs. Fin thickness ranges from 0.15mm to 0.4mm, balancing heat exchange performance and structural integrity. The in-line geometry and horizontal air intake/exhaust design minimize airflow resistance, while reinforced fan mounting plates reduce vibration during 24/7 continuous operation.

Defrosting & Fan Systems

The fast freezer evaporators support diverse defrosting methods—electric, hot gas, air, glycol, brine, and water defrosting—to adapt to different product and facility needs. Equipped with AC or EC fan motors, the system ensures consistent airflow distribution, a key factor in achieving uniform freezing. The integrated insulated water tray prevents ice buildup and ensures efficient defrost water evacuation.

Core Features

Hygienic & Durable Construction
