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

This machine can be customized for low temperature models using the low temperature cold medium
