[Overview]

This specialized chiller is engineered to meet the stringent thermal requirements of hard anodizing processes. Featuring advanced full-liquid screw compressor technology, it delivers precise temperature control for both cooling and heating applications, ensuring optimal performance and efficiency in hard anodizing operations.

[Key Features and Technical Parameters]

I. Temperature Control Capabilities

• Cooling Side Temperature: Precisely controlled within 18°C – 22°C (64.4°F – 71.6°F), ideal for oxidation cooling. This stable low-temperature environment ensures the quality and uniformity of the anodized coating.

• Heating Side Temperature: Reaches up to 90°C (194°F), suitable for processes such as acid etching, alkali etching, pure water washing, and hole sealing. This dual-temperature capability allows the chiller to serve multiple purposes in the anodizing line.

II. Energy Efficiency and Cost-Effectiveness

• Dual-Purpose Function: A true “two-in-one” solution, replacing both a boiler and an anti-corrosion chiller. This saves equipment investment and installation space.

• Operating Cost: Competitive at approximately 0.6 yuan/m³ of natural gas equivalent, offering significant long-term savings compared to traditional separate heating and cooling equipment.

III. Compressor and System Performance

• Semi-Hermetic Screw Compressor:

  • Equipped with 1-2 sets.

  • Input power: 58.4kW to 243kW.

  • Rated Full-Load Current: 97.8A to 396A. Highly reliable and stable across different load conditions.

• Unloading Mode: Supports stepless unloading in multiple levels (e.g., 0, 25, 50, 75, 100% or more refined ratios like 0-100% in 12.5% increments). This allows precise adjustment of cooling capacity to actual process load, minimizing energy waste.

IV. Heat Exchanger Specifications

• Condenser (High Efficiency External Finned Tube Shell and Tube Type):

  • Cooling Water Flow: 46.2m³/h to 254.7m³/h.

  • Water Pressure Loss: 62.0kPa to 71.0kPa.

  • Connection Size: Cooling water inlet/outlet diameters range from Dn100 (4 inches) to Dn200 (8 inches).

• Evaporator (High-Efficiency Anti-Corrosion Flooded Type):

  • Trough Liquid Flow: 83.7m³/h to 357.0m³/h.

  • Trough Liquid Pressure Loss: 58.0kPa to 64.0kPa.

  • Trough Liquid Temperature: Inlet 20°C (68°F), Outlet 18°C (64.4°F) for efficient heat exchange.

V. Physical and Safety Parameters

• Weight and Dimensions:

  • Weight: 2729kg to 8226kg.

  • Dimensions (L×W×H): e.g., JCK220 model: 2800mm×1250mm×2000mm; JCK900 model: 4600mm×1650mm×2300mm.

• Safety Protection: Comprehensive features including acid pump interlock, phase loss, over/under voltage, reverse phase, compressor over-temperature, high-pressure safety, oil level, and water-lack protection to ensure safe, stable operation and prevent damage.

[Suitable Industry Fields]

• Hard Anodizing Industry:

  • Aluminum Processing Plants: Provides accurate temperature control for all stages of hard anodizing (cooling, etching, sealing) of profiles and parts, critical for aerospace-grade aluminum.

  • Automotive Parts Manufacturers: Ensures consistent anodizing for wear-resistant and corrosion-resistant automotive parts (e.g., engine blocks, wheels) in mass production.

• Other Metal Processing Industries:

  • Precision Hardware Processing: Utilized for precise temperature control in acid etching and hole sealing for improved surface quality and accuracy (e.g., electronic connectors).

[Competitive Advantages]

• Precise Temperature Control: Dual temperature capabilities (cooling 18-22°C / 64.4-71.6°F and heating up to 90°C / 194°F) meet diverse hard anodizing needs, ensuring product quality stability.

• Energy Saving and Cost-Effective: Dual-purpose function and stepless unloading technology significantly reduce energy consumption and operating costs, offering clear economic advantages over traditional equipment combinations.

• Reliable and Durable: High-quality semi-hermetic screw compressors and multiple safety protections ensure stable operation in harsh industrial environments, minimizing maintenance costs and downtime.
