Water Screw Type Chiller Cooling System Water-Cooled Industrial Water Screw Chiller
Feature
Superior performance
Semi-hermetic screw compressor in-built motor avoid seal leakage
Two or a plurality of compressor controlled by PLC program, which can balance the load and prolong the service life of the unit.
Two or a plurality of compressor using multi refrigeration circuit, when a circuit be repaired or in maintenance, the remaining loop can still be operated normally
Compressor adopt duplex winding reduced-voltage starting, to avoid the impact to the electric network
Easy Installation
Compact structure, small occupation area.
The machine has been tested strictly and timing operation completed to reach the using state
Extremely vibration and don't need the vibration isolation equipment usually.
Low cost for operation and maintenance
Microcomputer control system make the chillers highly efficient in part load conditions as it adjusts
the capacity 0-25-50-75-100% volume control to save energy
Screw compressor in low failure rate with simple structure and few wearing parts
The built-in three stage oil separator
Adopt the coating design to reduce the compressor running noise
Water chiller compressor trouble-free operation over 40000 hours
Complete security protection function
High & low pressure protection
Anti-heating safety 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
Adopt brand-name PLC controller and colorful touch panel, friendly interface for simple operation
Automatic detect temperature of chilled water system, which tracking the load efficiently by adjusting the compressor
Main operation data for reference can be read in the display
Automatic failure alarm system can display the failure code for analysis
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 capacity position, 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
The central chillers are widely applied in the centralized cooling way
This unit can be customized for the acid and alkali resistant special models, which satisfied the special needs of customers with special process
