-15 ℃ water-cooled screw chiller

-15 ℃ water-cooled screw chillerself-controlA new control logic has been developed for the system, using a validated Siemens automation control system to provide warnings for critical system parameters,One click power on, automatic start stop, automatic load adjustment,Adopting high-precision large screen touch screen, industrial grade intelligent controller and advanced computer control system, fully digital Han display, connected to external devices, remote users and control rooms through standard interfaces, the following control functions can be achieved:

（1) Multiple protections: compressor exhaust over temperature, motor over temperature, cold water anti freezing, etc. Temperature protection: overcurrent, phase loss, reverse phase, etc. Electrical protection: refrigerant system high and low voltage, oil level, water cut-off and other emergency state protection

（2) Necessary maintenance and management functions such as alarm, prompt, recording, and retrieval can be set for the above protection functions

（3) Automatic power on/off, automatically achieving unmanned operation management according to the predetermined work plan

（4) Multiple password settings ensure that the device will not shut down or be damaged due to accidental factors

（5) Realize remote data collection, operation inspection and control, fault diagnosis and other management functions through LAN or InternetFlexible adjustable design can enable the unit toContinuous energy regulation (stepless energy regulation) between 25% and 100% ensures the full performance of the compressor and helps users save operating costs to the greatest extent possible

-The 15 ℃ water-cooled screw chiller can choose various refrigerants (chilled water) according to the user's needs: alcohol based refrigerants such as ethylene glycol aqueous solution, alcohol, ternary mixed solution, etc. The evaporator can also be equipped with anti-corrosion requirements Calculation, using calcium chloride aqueous solution;
