CORE BENEFITS

Engineered for profile oxidation processes, this high-performance chiller adopts a full-liquid flooded screw compressor design to deliver precise temperature control and efficient heat exchange.

🌡️

Consistent Oxidation Quality

Maintains precise oxidation process temperature at 19.5°C inlet / 18°C outlet (±0.5°C precision), ensuring uniform coating thickness and significantly reducing reject rates.

High Energy Efficiency

Optimized screw compressor system and flooded evaporator design deliver maximum cooling output with high energy efficiency and superior heat transfer performance.

🛡️

Reliable in Harsh/Corrosive Environments

Engineered for continuous heavy-duty industrial use, providing stable thermal performance even under high load and demanding processing conditions.

🔧

Lower Maintenance Cost

Comprehensive protection logic and modular system design minimize unexpected shutdowns and simplify routine maintenance procedures.

TECHNICAL FEATURES

Semi-Hermetic Screw Compressor System

Equipped with 1-2 high-efficiency screw compressors, supporting 10%–100% stepless capacity control to precisely match dynamic process loads.

Flooded Evaporator Design

Maximizes heat exchange efficiency and ensures highly stable outlet temperature for oxidation tanks (19.5°C inlet / 18°C outlet.Features a specialized anti-corrosion design for long-term durability in chemical environments.).

Industrial-Grade Heat Exchangers

Robust shell-and-tube condenser with optimized water flow patterns, specifically engineered for continuous operation.

Comprehensive Safety System

Integrated safeguards including PLC-based smart control, acid pump interlock, phase loss/reverse protection, over-voltage monitoring, and automatic emergency shutdown.

IDEAL APPLICATIONS

Aluminum & Section Bar Oxidation Lines
Metal Surface Treatment Industries
Industrial Anodizing Plants
Processes Requiring Strict Thermal Control

Technical Notes:

  • Standard Condition: Cooling capacity is based on chilled water outlet temperature of 7°C and inlet temperature of 12°C.
  • Oxidation Process Condition: Based on tank liquid inlet temperature of 19.5°C and outlet temperature of 18°C.
  • Performance Note: If the actual operating temperature is above 15°C, the cooling capacity will increase by more than 30%.
  • Noise Test: Noise is measured 1 meter in front of the main unit at a height of 1.5 meters, with average four-point values (ambient noise below 30dB).
