Air Cooled Low Temperature Water Chiller Anti Corrosive With Axial Fan

Technical Excellence: Advanced Screw Compression Technology

Engineered for Peak Volumetric Efficiency and Industrial Longevity

1. World-Class Compression Architecture

• Certified High-Efficiency Rotary Sub-Compressor: Our units utilize international-brand screw compressors that are ISO9001 certified and protected by European and US patents. These units deliver a documented 20%–30% increase in efficiency compared to conventional models, providing a significant competitive edge in energy consumption.

• 5:6 Patented Asymmetric Rotor Profile: The precision-machined 5:6 tooth ratio ensures superior gas tightness and minimal internal leakage. This optimized geometry allows for smoother rotation, reduced vibration, and maximum displacement per revolution.

2. Intelligent Load & Energy Management

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

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

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

  • Stepless Modulation (Optional): For ultra-precise applications, our stepless control system adjusts output in real-time to match the exact load, eliminating energy spikes.

• Optimized Volume Ratio (VI) Selection: We offer a full spectrum of compressor capacity ratios (VI=2.2/2.6/3.0/3.5). By selecting the VI that matches your specific pressure requirements, we prevent over-compression and under-compression, ensuring no energy is wasted during the cycle.

3. Reinforced Mechanical Durability

• Heavy-Duty 11-Bearing Design: While competitors use standard bearing counts, our compressors feature an 11-bearing architecture integrated with an axial thrust balance drum. This reinforcement neutralizes internal mechanical stress, extending bearing service life by 2.5 to 3.5 times and significantly reducing overhaul frequency.

• High-Performance Motor Cooling: The motor utilizes a specialized silicon steel sheet groove design. Combined with an omnidirectional cooling flow path, the motor maintains optimal operating temperatures even under 24/7 continuous full-load conditions, preventing insulation degradation.

4. Advanced Lubrication & Filtration Systems

• Passive Oil Management (Pump-less): Our unique built-in oil pressure system utilizes pressure differentials to maintain optimal lubrication. By eliminating the need for an external oil pump, we remove a common mechanical failure point and reduce parasitic power loss.

• Double-Layer Oil Separation: High-precision dual-stage filtration ensures that oil carry-over into the refrigerant circuit is virtually eliminated. This keeps the heat exchanger surfaces pristine, maintaining maximum thermal conductivity and system efficiency over time.

5. Multi-Refrigerant Versatility

Our engineering platform is fully compatible with a wide array of industrial refrigerants, allowing you to meet local environmental mandates (GWP/ODP) without sacrificing performance:

• Supported Media: Optimized for R22, R134a, and R407c (and other eco-friendly blends upon request).
