Hanbell's AC-420S is a high-performance, industrial-grade screw chiller designed for reliable and efficient cooling in demanding applications.
Technical Parameters
| Model | Power (kW) | Rotating speed (rpm) | Air Delivety (m3/min) | Shaft power (kW) | Specific power (kW/m3/min) | Dimension(mm) | Weight(kg) |
| AC-420S | 30 | 3000 | 4.5 | 31 | 6.89 | 453*353*280 | 100 |
High-Efficiency Screw Compressor: The core of the unit features Hanbell's proprietary semi-hermetic twin-screw compressor, known for its robustness, smooth operation, low vibration, and long service life.
Optimized Heat Exchangers: Utilizes high-efficiency shell-and-tube evaporators and condensers with enhanced internal tube design, ensuring superior heat transfer and stable performance under various load conditions.
Intelligent Control System: Equipped with a advanced microcomputer controller (typically a touch-screen interface). It enables precise temperature control, comprehensive system monitoring (pressures, temperatures, statuses), fault diagnostics, and energy management. Communication interfaces allow for remote monitoring and integration into Building Management Systems (BMS).
Energy-Efficient Design: Incorporates components like adjustable fans for the condenser coil and optional variable frequency drive (VFD) for the compressor motor, allowing capacity modulation to match the cooling load exactly and significantly reduce part-load energy consumption.
Wide Operating Range: Capable of stable operation across a broad range of condensing and evaporating temperatures, suitable for diverse climates and industrial cooling requirements.
Robust Construction & Protection: Built with industrial-grade components featuring multiple safety protections (high/low pressure, motor overload, phase sequence, anti-freeze, etc.) to ensure reliable and safe operation.
Refrigerant Options: Typically designed to use environmentally friendly refrigerants such as R-134a or R-513A, balancing performance with lower environmental impact.
Outstanding Reliability & Durability: The heavy-duty screw compressor and industrial design make it exceptionally reliable for 24/7 continuous operation, minimizing downtime and maintenance costs.
High Energy Efficiency: The combination of the efficient screw compressor, optimized heat exchangers, and capacity modulation technology results in excellent full-load and superior part-load efficiency (often evidenced by high IPLV values), leading to substantial operational cost savings.
Precise & Stable Cooling: Delivers precise temperature control (±0.5°C or better) and stable cooling capacity, which is critical for process applications.
Low Noise & Vibration: Screw compressors inherently operate with less noise and vibration than reciprocating compressors, making them suitable for installations where noise is a concern.
User-Friendly Operation & Maintenance: The intuitive controller simplifies operation and provides clear system data. Easy access to key components and a straightforward service design facilitate routine maintenance.
Strong Part-Load Performance: Unlike centrifugal chillers, screw chillers maintain high efficiency even at low load conditions (down to ~20-25% capacity), making them ideal for applications with variable loads.
Industrial Process Cooling: Plastic injection molding, metal plating, chemical processing, pharmaceutical manufacturing, laser cutting, food & beverage production.
Central Air-Conditioning Systems: Large office buildings, shopping malls, hotels, hospitals, airports, and campuses.
District Cooling Plants: As a reliable module within a larger district cooling network.
Energy Stations & Combined Systems: Integration into systems with heat recovery or thermal storage.
Specialized Facilities: Data centers (for precise environmental control), sports arenas, and convention centers.
