Customizable Air Cooled Screw Chiller Anti Corrosion 250HP Screw Type Chiller

The air-cooled screw chiller (single/double series) utilizes internationally renowned screw compressors (Taiwan Hanbell, Bitzer) paired with high-performance copper pipe evaporators and premium components. This combination delivers:

• Compact size with low noise operation
• High energy efficiency and extended lifespan
• User-friendly operation with reliable performance
• Superior design and build quality

• High-Precision Engineering & Compression Technology

  The Core of Industrial Reliability: Advanced Rotary Screw Architecture

  1. Superior Volumetric Efficiency

  • Next-Generation Rotary Sub-Compressor: Our units utilize international-brand, high-efficiency rotary sub-compressors. By optimizing internal clearances and mechanical friction, these units deliver 20%–30% greater energy efficiency compared to standard industry models, significantly lowering your annual electricity expenditure.

  • 5:6 Patented Asymmetric Rotor Profile: The precision-engineered 5:6 tooth profile ensures superior sealing and minimal "blow-back" during compression. This patented geometry maximizes gas displacement while reducing internal turbulence and noise.

  2. Intelligent Load Management

  • Granular Capacity Control: To match your facility’s fluctuating cooling demand, we offer versatile staging options:

    • Four-Stage Control: 100% – 75% – 50% – 25%

    • Three-Stage Control: 100% – 66% – 33%

    • Benefit: This allows the unit to throttle down during low-demand periods, preventing "short-cycling" and maintaining stable temperatures while saving energy.

  • Optimized Volume Ratio (VI Control): We provide a full range of compressor capacity ratios (VI = 2.2 / 2.6 / 3.0 / 3.5). By matching the VI to your specific operating conditions, the system prevents over-compression or under-compression, eliminating unnecessary energy waste.

  3. Extended Mechanical Longevity

  • Industrial-Grade 11-Bearing Design: While standard compressors use fewer supports, our 11-bearing architecture features a dedicated thrust balance drum. This configuration neutralizes axial forces, extending the bearing service life by 2.5 to 3.5 times compared to conventional designs.

  • High-Efficiency Silicon Steel Motor: The motor utilizes a special groove design made from high-grade silicon steel sheets. Combined with omnidirectional cooling, this ensures the motor remains at peak efficiency even during 24/7 continuous operation in high-ambient environments.

  4. Advanced Lubrication & Filtration

  • Integrated Oil Pressure Management: The built-in oil pressure system operates via pressure differentials, eliminating the need for an external oil pump. This simplifies the mechanical footprint and removes a common point of failure.

  • Dual-Layer Oil Filtration: A high-precision, double-layer filtration system ensures that only clean oil reaches the bearings and that oil carry-over into the refrigerant circuit is minimized. This keeps the heat exchanger surfaces clean, maintaining high thermal conductivity over the life of the machine.

  5. Global Refrigerant Compatibility

  Our systems are engineered for global versatility, supporting a wide array of refrigerants to meet local environmental regulations and performance requirements:

  • Standard & Eco-Friendly Options: Fully compatible with R22, R134a, and R407c, allowing you to choose the optimal medium for your specific cooling capacity and GWP (Global Warming Potential) targets.

This air-cooled screw chiller serves multiple industries with exceptional performance:

• Chemical Industry: Custom acid-proof units for reactors and condensers in corrosive environments
• Pharmaceutical: Precise temperature control for drug production stability
• Electronics: Ultra-low temperature cooling for chip manufacturing and LCD production
• Commercial: Low-noise operation for shopping malls, hotels, and office buildings

The air-cooled system provides consistent cooling without water dependency, making it ideal for remote facilities or water-restricted areas.
