Water cooled screw chiller (double models / 7 ° C)

Product Description

MAINLY UNIT FEATURE OF SCREW COMMPRESSOR 

Superior performance
- Adoption international advanced third generation 5: 6 semi-hermestic screw compressor, the motor and compressor integration, without seal leakage concerns
- Two or a plurality of compressor combination precision control program is reasonable and balanced the handpiece assembly load, prolong the service life of the unit
- Two or a plurality of compressor using multiple sets of refrigeration circuit, when a circuit must be repaired and maintenance, the remaining loop can still be operated normally, with standby function
- Compressor with duplex winding reduced-voltage starting, avoid the impact to the electric network

Easy Installation
- Compact structure, small occupation area, saving the space
- The machine has been checked ststrictly and timing operation completed to reach the using state
- Based minimum vibration, don't need the vibration isolation equipment usually, simple installation
- Just need connect with the cooling water chilled water pipe of evaporator and condenser 

Low cost for operation and maintenance
- Unit can be controled by intelligent program according to the load needs: 0-25-50-75-100% volume control to save energy. 
- Screw compressor has simple structure, few wearing parts, the failure rate is very low
- The built-in oil separator using three stage oil filter; Adoption the coating design to reduce the compressor'noise
- Water chiller compressor trouble-free operation over 40000 hours

Complete security protection function
- High & low pressure protection
- Anti-heatingsafety valve 
- Anti freezing protection
- Overload protection, 
- Incomplete phase protection
- Opposite phase protection
- lacking voltage and over voltage protection
- Water flow protection

Humanized microcomputer control system
- Adoption brand-name PLC liquid crystal color LED display, touch panel computer control, the Chinese interface for simple operation
- Automatic detect outlet temperature of chilled water system, effective tracking site load by adjusting the compressor
- The display is intuitive, can be readily read operation data for reference
- Automatic failure alarm system can display the failure code to handle
- Output feedback information to the other main control system based on the needs of field
- The original content can be modified based on the field needs, such as position of each unit, protection, pressure etc. 

Application of the strong widely
- Widely used in rubber, plastic, petroleum, chemical, electronics, textile, papermaking, brew, pharmaceutical, machinery, food, beverage, vacuum coating, plating, coating, central air-conditioning and other fields
-This machine series is widely applied in the centralized cooling way
- This machine can be customized for the acid and alkali resistant special models, the special needs of customers with special process
- This machine can be customized for low temperature type special models using the low temperature cold medium, to reach the customer special technology of special needs.
