Precision Cooling Semi-Hermetic Flooded Twin Screw Chiller for Sale

Product Description

Product Description

The SJSW series inherits the hallmark features of American flooded screw chillers: high efficiency, energy savings, superior reliability, and simple, convenient control.Enhanced heat exchange tubes significantly boost the vessel's heat transfer capacity. Coupled with twin screw compressor technology, this greatly improves system efficiency.The multi-compressor design not only enhances partial load efficiency but also improves unit redundancy for better reliability.Equipped with Siemens controllers and a touchscreen LCD panel, the unit allows easy operation and monitoring.We have intentionally avoided unnecessary and complicated features, focusing instead on simplicity and reliability. This economical and practical twin screw chiller is designed to meet customer needs without overcomplication.

Our advantages

1.Patented Twin Screw Compressor, High Efficiency and Low Noise

Sujing utilizes well-known brand semi-hermetic twin screw compressors, offering higher efficiency and reliability. The compressor features suction cooling for excellent heat dissipation.The motor directly drives the rotor, resulting in fewer moving and wear-prone parts and delivering high mechanical efficiency.

2.Simple Oil Return Without the Need for an Oil Pump

Featuring a unique compressor oil return design, the system enables straightforward oil return without requiring an oil pump, effectively eliminating the risk of heat exchanger freeze damage.

3.Twin-screw compressor linear measurement

The patented 5:6 asymmetric rotor tooth shape is used and is processed by a special high-precision rotor grinding machine, with good precision and stable quality. Under continuous operation, the rotor can maintain the optimal clearance value to achieve the highest efficiency requirements.
