As one of China's earliest professional manufacturers of purification air conditioners and HVAC equipment, Sujing specializes in R&D, production, sales, and installation. We operate two core segments: air conditioning systems and heat pump systems. The heat pump line includes CO2 heat pumps, cascade variable frequency units, air source (chilled water) units, water-cooled chillers, industrial screw units, air-cooled modules, and drying units.
Our products are widely applied in industry, agriculture, commerce, transportation, and aerospace, as well as in specialized fields like green heating, coal mines, oil fields, livestock farming, agricultural drying, and biomedicine. They are exported to over 30 countries, including the U.S., Finland, the Netherlands, Canada, and Brazil.
SJFX Series Flooded Water Cooled Screw Unit
The SJFX series full liquid type semi-closed twin-screw chiller unit features high efficiency,energy saving,high reliability,and simple and convenient control.
The enhanced heat exchange tube significantly improves the heat exchange capacity of the unit,combined with twin-screw compressor technology,greatly improving system efficiency;multi-compressor design not only achieves higher efficiency at partial loads,but also enhances unit redundancy.
Equipped with Siemens controllers and a touch-screen LCD display,it easily achieves operation and monitoring of the unit.At the same time,we have abandoned some flashy but impractical functional designs and,based on the concept of simple operation and reliable performance,have introduced this economical and practical screw-type chiller unit to our customers.
