High-Capacity Twin-Screw Compressor System:
Features dual, independent Hanbell semi-hermetic twin-screw compressors, each driving a dedicated refrigerant circuit.
Compressors are engineered with large rotor profiles, precision bearings, and oil management systems optimized for maximum efficiency and durability at high cooling capacities.
Dual Fully Independent Refrigerant Circuits:
The chiller is configured as two complete, standalone 725RT (approximate) chillers within a single package. Each circuit has its own compressor, condenser, evaporator section, controls, and refrigerant piping.
This architecture provides inherent N+1 style redundancy at the 50% capacity level and exceptional operational flexibility.
Optimized Large-Scale Heat Exchangers:
Incorporates high-efficiency shell-and-tube evaporators and condensers, typically designed as independent bundles per circuit or in a common shell with internal separation.
Utilizes enhanced surface tubing and optimized water pass arrangements to maximize thermal transfer and minimize pressure drop.
Advanced Dual-Module Control System:
Employs a master-slave or fully integrated multi-CPU control system, often based on an industrial PLC platform.
Features a large graphical touch-screen HMI for centralized monitoring, control, and data logging of both circuits.
Includes advanced functions like adaptive load sequencing, predictive maintenance alerts, extensive fault diagnostics, and seamless integration with central BMS/EMS.
Integrated High-Efficiency Components:
Standard variable frequency drives (VFD) on all compressors for true 15-100% capacity modulation per circuit.
High-efficiency, low-sound fans with VFD or EC motor control on the condenser coils.
High-efficiency pumps for internal refrigerant cooling circuits (if applicable).
Robust, Service-Oriented Construction:
Heavy-duty structural steel frame designed for stability and to support large component weights.
Component layout prioritizes service accessibility. Major components like compressors, oil separators, and control panels are easily reachable.
Comprehensive multi-stage safety protection system covering pressure, temperature, current, phase, and flow.
Sustainable Refrigerant Platform:
Designed for use with modern, lower-GWP refrigerants such as R-513A or R-134a, balancing performance with environmental responsibility.
Unparalleled System Reliability and Redundancy:
The dual, fully independent circuit design is the primary advantage. It ensures continuous cooling operation even during maintenance on one circuit or in the event of a major component failure, providing exceptional uptime for mission-critical applications.
Industry-Leading Part-Load Efficiency:
The combination of dual independent circuits and full VFD control on compressors allows the chiller to match any building load with extreme precision. At low loads, one circuit can be shut off entirely while the other modulates down, operating near its peak efficiency point. This results in exceptionally high IPLV and NPLV values, drastically reducing annual energy consumption.
Operational Flexibility and Scalability:
Operates as a single large unit or as two medium-sized units. Circuits can be set to different set points or staggered for load balancing.
Simplifies plant design by providing a large capacity in one footprint, reducing the number of separate chillers, pumps, and connections required.
Predictable Performance and Stable Control:
Advanced control algorithms ensure precise leaving water temperature control (±0.3°C or better) and smooth transitions between operating modes, protecting sensitive processes.
Optimized Lifecycle Cost:
While the initial investment is significant, the dramatic energy savings, reduced risk of costly process downtime, extended equipment life due to reduced cycling, and simplified maintenance planning lead to a superior Total Cost of Ownership (TCO) over 15-20 years.
Central Utility Plants for Major Facilities:
Large international airport terminals, major medical center complexes, university district energy systems, and government campuses.
Heavy Industrial Process Cooling:
Large automotive assembly plants, mega-plastic molding facilities, continuous-process chemical plants, and large-scale metal production facilities.
Core District Cooling Plants:
As a primary chiller in a district energy network serving a downtown area, large mixed-use development, or industrial park.
Mission-Critical Infrastructure:
Hyperscale data center cooling (indirect via chilled water), semiconductor manufacturing cleanrooms, and large pharmaceutical production facilities.
Major Entertainment and Sports Venues:
Stadiums, arenas, large convention centers, and entertainment resorts requiring massive, reliable cooling.
