Huihui's HHPA/DZ seriesAir-cooled screw-type low-temperature chiller unitAvailable for -65℃ to 5℃ low-temperature water solutions and 5℃ to 25℃ chilled water, widely used in ice storage air conditioning, low-temperature air supply industrial air conditioning, low-temperature process chilled water, and various other applications requiring chilled water above -65℃.

Product Features

       ◆Air-cooled screw-type low-temperature water chiller unitIndependent refrigeration system design, with relatively independent multi-head units, minimizing moving parts for reliable operation.

◆ Equipped with imported high-efficiency and economic semi-hermetic twin-screw compressors, offering high energy efficiency, reliable operation, and long lifespan.

◆ Under minimum load (25%), the compressors of various refrigeration systems start with a star-delta reduction voltage, effectively reducing the starting current and impact on the power grid.

Flexible adjustable design allows for continuous energy adjustment (stepless adjustment) of the air-cooled screw chillers over a 25% range, ensuring full compressor performance and helping users save operation costs to the maximum extent.

       ◆Air-cooled screw type low-temperature chiller unitEquipped with a high-precision large-screen touch screen, industrial-grade intelligent controller, and advanced computer control system, featuring full digital display. It can be connected with external devices for unified control, and remote users and control rooms can be connected via standard interfaces, enabling multiple control functions.

◆ Multi-protection functions: temperature protection for compressor exhaust overheat, motor overheat, and cold water anti-freezing; electrical protection for overcurrent, phase loss, and reverse phase; abnormal state protection for refrigerant system high and low pressure, oil level, and water cutoff, etc. Optional maintenance and management functions such as alarms, prompts, records, and searches for the above protection features.

◆Automatic on/off, achieving unmanned operation and management according to the predetermined work schedule.

◆ Multi-factor password settings ensure that the equipment will not be inadvertently shut down or damaged.

Remote data collection, operation inspection and control, fault diagnosis, and other management functions are achieved through a local area network or the INTERNET.

We select internationally branded thermal expansion valves, solenoid valves, check valves, and other control components to ensureAir-cooled screw-type low-temperature chiller unitEfficient and reliable performance across a broad range of operating conditions.

◆ Utilizes a dual-cycle heat exchanger refrigeration method with an energy-saving enhancer to improveAir-cooled screw chillers for low-temperature chilled waterWorkability and energy-saving efficiency.

◆ Products are factory tested and pass full-load operation tests before being shipped with refrigerant, ensuring the equipment can start working immediately upon water and electricity supply.

The compressor is equipped with a patented exhaust gas separator, ensuring low noise operation for the air-cooled screw chiller unit.

◆Air-cooled screw type low-temperature chiller unitAll refrigeration components are brand-name, enhancing the overall reliability of the unit.
