The HanBell AB-1900R is a large-capacity, industrial-grade water-cooled screw chiller designed for reliable, high-efficiency cooling in demanding continuous operations. It is built around HanBell's proprietary twin-screw compressor technology, which is the core of its performance.
Technical Parameters
| Model | Power (kW) | Rotating speed (rpm) | Air Delivery (m3/min) | Shaft power (kW) | Specific power (kW/m'/min) | S.F. | Dimension(mm) | Weight(kg) |
| AB-1900R | 185 | 2950 | 29.8 | 186.6 | 6.2 | 101 | 1164*748*535 | 975 |
High-Efficiency Twin-Screw Compressor:
At its heart is a HanBell brand twin-screw compressor known for exceptional durability and efficiency. Its asymmetric rotor profile ensures smooth, low-vibration compression with high volumetric efficiency.
Features continuous capacity control (typically from 10% to 100%) via a sophisticated sliding valve mechanism, allowing the chiller to precisely match cooling output to the load, saving significant energy.
Outstanding Energy Performance:
Engineered for a high Integrated Part Load Value (IPLV), meaning it operates very efficiently under the partial-load conditions where chillers spend most of their running time.
Utilizes optimal heat exchanger design and high-efficiency components to minimize power consumption per ton of cooling (kW/ton).
Robust Construction & Reliability:
Built with heavy-duty industrial components for 24/7 operation. The screw compressor has fewer moving parts and less wear than reciprocating compressors, leading to longer service life and lower maintenance.
The oil management system is highly effective, ensuring proper lubrication and efficient oil return, which is critical for compressor longevity and heat exchanger performance.
Intelligent Control System:
Equipped with a advanced microcomputer controller (like a PLC or touch-screen interface). It provides precise monitoring of all operational parameters (temperatures, pressures, currents), system diagnostics, alarm protection, and automated sequencing for multi-unit systems.
Often includes capabilities for remote monitoring and integration into Building Management Systems (BMS).
Flexible Design & Wide Operating Range:
Can be configured for various refrigerants (e.g., R134a, R513A, R514A) to meet environmental regulations and efficiency goals.
Designed to operate stably across a wide range of condenser water and chilled water temperatures, suitable for diverse climates and industrial processes.
Superior Energy Savings: The combination of the efficient screw compressor and seamless capacity control results in substantial reductions in electricity costs, especially in applications with varying loads. The high IPLV is a major competitive advantage.
Exceptional Reliability & Longevity: The industrial design and robust screw compressor make the AB-1900R extremely dependable for mission-critical cooling, minimizing downtime.
Low Maintenance Requirements: The simplicity and ruggedness of the screw compressor lead to less frequent and less costly maintenance compared to centrifugal or reciprocating chillers in its class.
Stable Performance: Provides precise and stable chilled water temperature control, which is vital for process quality in industrial settings.
Quiet and Smooth Operation: Twin-screw compression generates less noise and vibration than many alternatives, contributing to a better plant environment.
Chemical & Pharmaceutical Manufacturing: For process cooling, reactor temperature control, and condensation processes. Its precision and reliability are crucial.
Plastics & Rubber Industries: Cooling for injection molding machines, extruders, and blow molding equipment to ensure product quality and cycle times.
Food & Beverage Processing: Providing chilled water for fermentation control, cooling tunnels, ingredient mixing, and cold storage facilities. Hygiene-compliant versions may be available.
Central Plant Cooling for Large Facilities: Serving as the primary chiller in hospitals, district cooling systems, large hotels, or manufacturing campuses.
Metal Plating & Electrolytic Processes: Temperature control of plating baths and various washing/rinse stages to maintain process consistency and efficiency.
Data Center Cooling: In high-density data centers where precise, reliable, and efficient cooling is non-negotiable for server operation.
Automotive Manufacturing: For paint booth temperature/humidity control and cooling of various testing and production processes.
