Product Description

100HP 120HP 140HP Dual Refrigeration Circuit screw chiller Dual compressor air cooled screw chiller 

The double compressor screw chiller offers several advantages:

1. Increased reliability: The dual compressor configuration provides redundancy, ensuring that even if one compressor fails, the other can continue to operate, minimizing downtime and maintaining the cooling capacity.

2. Enhanced efficiency: By using two compressors, the load can be distributed between them based on the cooling demand. This allows for better matching of the chiller capacity to the actual load, resulting in improved energy efficiency and reduced operating costs.

3. Improved control and flexibility: Double compressor screw chillers often have advanced control systems that allow for precise control of each compressor. This enables better load management, load balancing, and capacity modulation, leading to optimized performance and flexibility in response to varying cooling requirements.

4. Better part load performance: With two compressors, the chiller can operate efficiently even at part load conditions. The ability to modulate capacity offers better performance in applications where the cooling demand varies throughout the day or across different seasons.

5. Redundancy and reliability in critical applications: In critical applications where continuous cooling is crucial, the dual compressor configuration provides an added layer of redundancy. If one compressor requires maintenance or encounters an issue, the other can take over the entire cooling load, ensuring uninterrupted operation.

Overall, the advantages of a double compressor screw chiller include improved reliability, enhanced energy efficiency, better control and flexibility, superior part load performance, and increased redundancy for critical applications.

An air cooled screw chiller is a type of refrigeration system used for cooling applications. It uses a screw compressor as the main component to circulate the refrigerant and remove heat from the system. Unlike water cooled chillers that require a separate cooling water source, air cooled screw chillers use ambient air as the cooling medium.

The application of air cooled screw chillers is wide-ranging and can be found in various industries and processes, including:

1. Commercial Buildings: Air cooled screw chillers are commonly used in office buildings, hotels, shopping malls, and other commercial facilities for air conditioning and HVAC (Heating, Ventilation, and Air Conditioning) applications.

2. Industrial Processes: They are utilized in industrial processes that require cooling, such as plastic manufacturing, rubber processing, metalworking, pharmaceutical production, food and beverage processing, and chemical manufacturing.

3. Data Centers: Air cooled screw chillers can provide cooling for data centers to maintain optimal temperatures for servers and sensitive electronic equipment.

4. Power Plants: They may be used for cooling in power generation plants, specifically for cooling turbine generator units and other equipment.

5. Hospitals: Air cooled screw chillers play a crucial role in providing cooling for critical areas in hospitals, such as operating rooms, laboratories, and medical equipment rooms.

6. Event Venues: They are frequently employed in convention centers, concert halls, and stadiums to maintain comfortable temperature conditions for large gatherings.

Air cooled screw chillers offer advantages such as simplified installation (no need for a separate cooling tower or water source), reduced water consumption, flexibility in installation locations, and ease of maintenance. However, they generally have slightly lower cooling capacity compared to water cooled chillers and may be affected by ambient temperature and air quality.
