Falling Film Screw Chiller

I. Yuzhen Falling Film Screw Chiller: Product Core Architecture and Technical Highlights

As a flagship model in Yuzhen's industrial and commercial refrigeration portfolio, this Falling Film Screw Chiller is designed with "efficiency + reliability + intelligence" as its core design logic. Key configurations are as follows:

It uses Hanbell's independently developed semi-hermetic twin-screw compressor (international certifications: ISO-9001, UL, CE, Swiss Lloyd's Register, etc.), with the motor and compressor integrated into a single unit, preventing oil leakage; it boasts high transmission efficiency and low operating noise.  Combined with an independent ejector pump oil return system, it ensures stable oil return even under full load conditions, significantly extending the unit's lifespan.

High-Efficiency Heat Exchange: Falling Film Evaporator + Baffle Plate Condenser

Falling film evaporator: The refrigerant covers the heat exchange tubes in a thin film, improving heat transfer efficiency by more than 15% compared to traditional models, and requiring less refrigerant, aligning with environmentally friendly procurement trends;

Baffle plate condenser: The compartmentalized flow design reduces the condensation temperature by 0.5℃~1℃, providing even better energy efficiency advantages for large-tonnage units.

Precise Flow Control: Customized Orifice Plate Throttling Device

Each set of orifice plates is "tailor-made" for the performance of the Yuzhen unit. A combination of 2-3 plates achieves dynamic throttling, automatically adapting the refrigerant flow rate under full load/partial load conditions. The design without moving parts makes its reliability far superior to traditional throttling valves, making it a typical configuration for "low maintenance costs" in industrial procurement.

II. Intelligent Operation and Maintenance: The Digital Control Advantages

The "advanced control system" of the Yuzhen Falling Film Screw Chiller is a core advantage in procurement decisions, particularly regarding "operational efficiency":

Millisecond-level Microcomputer Controller

Equipped with a microcomputer controller with a processing speed of 0.25ms/1K Words, coupled with PID precise temperature control, it can stabilize the water temperature within ±0.3℃ of the target value, meeting the high requirements of precision industrial refrigeration.

Visual Human-Machine Interface and Cloud Connectivity

The touchscreen supports real-time monitoring of the unit status, and operation requires only clicking on the interface; a Modbus-RTU communication interface is reserved for seamless integration into building monitoring systems, allowing purchasers to achieve remote alerts and centralized management without additional deployment.

30+ Comprehensive Protection Functions

Covering all aspects of protection (such as password locking, condenser cleaning reminders) for power supply, compressor, and system operating conditions, ensuring "safe operation throughout the entire lifecycle" of the unit from the procurement stage.

III. Procurement Value

For corporate procurement, the core value of the Yuzhen Falling Film Screw Chiller lies in "scenario coverage + cost optimization":

Multi-condition Adaptability

Supports single/dual unit combinations (maximum cooling capacity up to 410RT), R22/R134a refrigerant switching, and multiple voltage/starting method options. Whether for large commercial complexes or industrial production workshops, customized models can be matched to meet specific needs.

Total Life Cycle Cost Advantages

Energy saving: Falling film evaporation + high-efficiency compressor, improving energy efficiency ratio by 10%~15% compared to traditional units;

Low maintenance: Designs such as non-moving part throttling devices and refrigerant-cooled oil coolers significantly reduce maintenance frequency and costs;

Reliability Backed by Authority

Each unit has passed the full-performance test of the National Compressor Quality Inspection Center. Our compressors have a leading global market share and a reputation as the industry leader since 2006, giving purchasers peace of mind regarding product quality and after-sales service.
