I. Cooling Capacity & Efficiency:

• Range:

  • Cooling capacity: 8.4kW (JCX8FGH) to 80.4kW (JCX40FGH*2).

  • USRT (ton of refrigeration): 2.4 to 22.8.

  • Kcal/h: 7224Kcal/h–69144Kcal/h.

• COP (Energy Efficiency Ratio):

  • Maintains 2.0–2.1 across models.

  • Example: JCX25FGH (25.5kW cooling) achieves a COP of 2.0, reducing long-term operating costs.

II. Compressor & System Design:

• Semi-Hermetic Scroll Compressors:

  • Equipped with 2–4 sets of fully enclosed scroll compressors.

  • Input Power: 4.1kW–39.2kW.

  • Rated Full Load Current: 7.3A–66.4A. Ensures reliable operation under heavy loads.

• Unloading Modes:

  • Supports stepless unloading (e.g., 0, 25, 50, 75, 100% for some models).

  • Adapts cooling capacity to dynamic process demands, minimizing energy waste.

III. Heat Exchanger & Corrosion Resistance:

• Condenser (High-Efficiency Internally Finned Tube Type):

  • Cooling Fan Power: 0.30kW–3.5kW.

  • Features air-cooled heat exchange via copper-aluminum fins for efficient heat dissipation.

• Evaporator (High Efficiency Anti-Corrosion U-Tube Dry Type):

  • Bath Solution Flow: 1.4m³/h–31.9m³/h.

  • Maintains stable bath temperature: -2℃ inlet / -5℃ outlet (28.4℉/23℉).

  • Corrosion-resistant design handles acidic/alkaline bath solutions (15%–25% sulfuric acid), ideal for hard oxidation.

IV. Safety & Adaptability:

• Comprehensive Protections:

  • Includes pump interlock, phase loss protection, over-voltage protection, and compressor over-temperature shutdown.

  • Ensures 24/7 operation and prevents equipment damage.

• Custom Piping:

  • Bath solution connections use Dn15 (0.59 inches) to Dn80 (3.15 inches) pipes.

[Industry Applications]

• Hard Oxidation & Anodizing:

  • Aluminum Processing Plants: Provides precise 7℃/44.6℉ cooling for sulfuric acid bath oxidation, ensuring uniform oxide layer thickness and surface quality for aerospace, automotive, and architectural components.

• Electroplating & Surface Treatment:

  • Stabilizes temperatures for acid copper plating, chrome plating, and zinc plating—improving coating adhesion and finish consistency.

• Other Metal Processing:

  • Precision Hardware Manufacturing: Cools molds and finishing lines for stainless steel, brass, and other metals, ensuring dimensional accuracy and corrosion resistance.

[Competitive Advantages]

• Process-Specific Design:

  • Tailored for hard oxidation: corrosion-resistant materials and -2℃/-5℃ (28.4℉/23℉) bath temperature control meet strict industry standards.

• Energy Efficiency:

  • High COP (2.0–2.1) and smart unloading reduce energy costs by 15%–20% compared to generic chillers.

• Durability:

  • Heavy-duty compressors and anti-corrosion heat exchangers ensure a service life of 10+ years in harsh industrial environments.
