Dry Screw Chiller

In industrial scenarios demanding long-term stable operation, Yuzhen's Dry Screw Chiller has attracted customer attention with its unique orifice plate throttling technology and integrated semi-hermetic compressor. It solves the troublesome problem of frequent maintenance

Highlight 1:

Millisecond-level computing power: The internal microcomputer executes a 1K Words program in just 0.25 milliseconds. This means that when your process load changes, the unit can adjust instantly, completely eliminating the "sluggishness" of traditional equipment.

±0.3℃ "Constant Temperature Commitment": Relying on PID automatic control, the water temperature remains rock-steady regardless of external environmental changes, greatly protecting the service life of precision production equipment.

Visualized collaboration: The touchscreen is extremely responsive, providing instant feedback. It not only supports local operation but also seamlessly integrates with building or factory monitoring centers via Modbus-RTU for remote control.

Structural Revolution

Many users are most concerned about throttling valve jamming or sensor failure when purchasing a Dry Screw Chiller. Yuzhen directly solves this problem through its physical structure:

Orifice Plate Throttling (Exclusive Highlight): We do not use mechanically driven throttling valves, but instead use a customized orifice plate assembly based on performance requirements. It has no moving parts and uses the refrigerant's own dynamic balance to control the flow rate.

Zero-lag response: Whether at full load or partial load, the orifice plate can adjust instantly, without mechanical delay, resulting in extremely stable operation.

Ejector Pump Oil Return: Cleverly utilizes differential pressure for oil return, requiring no additional energy consumption and eliminating the risk of traditional oil pump failure.

Highlight 3: Hanbell Original Semi-Hermetic Compressor

The core power source comes from the world-leading Hanbell:

The Dry Screw Chiller adopts a semi-hermetic design with the motor and compressor in the same housing, which not only eliminates the common shaft seal leakage problems of open-type units but also retains the structural advantages of easy maintenance.

The motor shaft and the rotating rotor are integrated, resulting in direct and efficient power transmission, with noise and vibration performance at the industry's top level. Falling Film Evaporator: The refrigerant is sprayed from top to bottom, covering the heat exchange tubes with only a thin film of refrigerant. This results in extremely high heat exchange efficiency and low refrigerant charge, truly achieving green and energy-saving operation.

Highlight 4: Multiple Defense Systems, Making "Unexpected Shutdowns" a Thing of the Past

30 Safety Guards: From voltage imbalance protection to evaporator anti-freeze protection, the unit constantly performs self-checks, preventing damage caused by any abnormal startup.

Integrated System: Control interfaces for the cooling pump and fan are pre-installed, allowing the entire circulation system to be controlled by the unit's central control system, optimizing the overall system architecture.
