Air Cooled Screw Water Chiller, Industrial Cooling System

Product Description

Sincerely welcome to visit our factory at your convience. Customer could witness their order production real conditions by online videos or photos at any time during production.

SEMI-HERMETIC COMPRESSOR
Semi-hermetic screw compressor for the whole range. Each compressor is equipped with a crankcase heater and
a built-in electronic protection. The compressor steps or stepless energy control, adapt to the changes of different part load.

EVAPORATOR
Evaporator built with high efficiency horizontal type shell and tube heat exchanger, with stable, low resistance and
efficient heat exchange.

CONDENSER
Condenser built with seamless copper tubes mechanically expanded into blue hydrophilic aluminum fins. Low noise, energy saving axial fan, guarantees long service life of the unit.

REFRIGERANT CIRCUIT
Circuit is complete with sight glass, filter drier, high and low pressure gauges, solenoid valve, electronic expansion valve, high and low pressure switch, safety valve.

ELECTRIC PANEL
Electric panel consist of: Compressor contactor, fan motor contactor, compressor protection breaker, fan protection breaker, phase sequence relay and microprocessor with function display (display only for master/packaged unit) Automatic operation dramatically reducing maintenance cost thanks to reliable microprocessor system.

CONTROL SYSTEM
Each unit is equipped with known brand PLC control system. This system is to provide precise and stable
control in long-term running. Meanwhile, it offers perfect communication function, which is convenient to realize
interface with building control system.

OPTIONAL
• Rubber anti-vibration mounting..
• Compressor soft connection
• BMS
• Stainless steel covering
• Heat recovery 20%-25%
• Remote condenser
