Cooling Capacity: 1046～3198KW
Outlet Temperature of Coolant: -10～-35℃
Features
● Advanced design
Optimum aerodynamic design of chiller is done by the centrifugal compressor software from CONCEPT NREC (USA) and CFD (computational fluid dynamics) software from NUMECA FINE/TURBO. Strength analysis, rotor dynamics and bearing analysis etc. has done by ANSYS，DYROBES software, improving optimal performance.
● Unique Feature
CQGI's patent shrouded compressor is driven by two ends of motor, having a wide range of cooling capacity and good performance in different working conditions. High pressure section and low pressure section of compressor are mounted on the two ends of motor respectively. The different speed of high pressure section and low pressure section makes centrifugal refrigeration machine have higher cooling efficiency. Main motor and compressor are mounted together, with good featuring seal and compact structure.
This kind of semi-hermetic integrated centrifugal low temperature refrigeration machine (-11℃～-35℃）fills in the blank of domestic market.
● Advanced manufacture
3D impeller is processing on the Deckel Mahao 5-axis machining center from Germany. Impeller profile test is done on the Carl Zeiss 4 coordinate measuring system from Germany, ensuring accuracy of impeller profile. Spin test of impeller is done on the Schenck Spin Test Stand from Germany. The dynamic balance test is done on the Schenck Dynamic Balance Machine from Germany, ensuring good quality of products.
● High automation
Special microprocessor control system. The key elements of specially designed microcomputer system are imported from OMRON Company, Japan, characterized by touch screen, simple operation and direct vision.
All performance and protection information are displayed on the screen at any time. The electric control cabinet has more than 30 control and safety functions and can record the history of last 10 shutdowns. The control system is equipped with RS422 interface control, so multiple-unit centralized control is available, otherwise, it can connect to building automation system (BASO) so as to remote control (start/stop of chiller).
Application：Chemical process flow, chlor-alkali industry etc.
