Observation Elevator,Panoramic Elevator,Sightseeing Elevator Observation Elevator Co., Ltd. , http://www.cn-elevators.com
1. Our factory in Shanghai-15000 square meters
2. Festures for air cooled screw chiller
1) Cooling capacity: 180kw~1520kw
2) Cooling conditions: Chilled water inlet temperature is 12 degrees, outlet temperature is 7 degrees Ambient temperature is 35 degrees
3) Input power: 3P-380V-50Hz, Allowable fluctuate voltage: ± 10%, allowable voltage difference in phase: ± 2%.
4) Measuring noise spot: 2m ahead and 1.5m high in front of chiller with average measurement on four dimensions.
5) Semi-closed 5: 6 asymmetric twin-screw compressor from world-renowned brand, trouble-free operation over 100000hours.
6) Eight stages volume control or 0%-100% automatic regulation.
7) Fluoride-resistant high-performance motor from French.
8) Use PLC microcomputer control from Germany Siemens LCD touch screen, both English and Chinese human-machine interface.
9) Wide range of variable chilled water temperature to meet the industrial requirements throughout whole year.
10) Friendly choose to use environmentally R407C or R134A refrigerant.
11) Free step-down triangle stars starter
12. Dual refrigeration circuits to each other back-up
3. Pictures reference for air cooled screw chiller
