Used in rubber and plastic, chemical and pharmaceutical, aluminum profiles, food processing, grinding and stirring, new energy and other fields.
High efficiency full - liquid screw chiller product advantages
1. High efficiency and energy saving: Adopt high performance twin screw compressor and new high efficiency heat exchanger, full load energy efficiency ratio up to 5.9, Partial load energy efficiency ratio up to 6.5;
2. Falling film evaporator has good heat transfer effect, liquid film evenly distributed in the copper tube, heat transfer coefficient is 30% higher than ordinary
3. User-friendly operation interface: Germany "SIEMENS" PLC programmable touch screen controller, simple and intuitive operation;
4. Multiple protection, safe and reliable: over and under voltage, lack of phase, reverse phase, overload, motor overheating and exhaust temperature too high protection;
5. Easy installation: the running test has been completed before delivery, refrigerant and frozen oil have been added, and users can simply connect to put into use;
6. Perform unmanaged operation
7. Frequency conversion starting mode, energy saving and electricity saving.
