Water Cooled Screw Chiller For Injection Molding Plastic High Effective Industrial Water Cooling System

Feature Highlights:

This water-cooled screw chiller offers high cooling capacity from 30 ton to 250 ton, with energy-saving performance, suitable for large-scale industrial applications such as chemical plants and automotive manufacturing. It features a semi-hermetic screw compressor for stepless capacity control, a shell and tube evaporator condenser for high efficiency, and precise temperature control within 3°C to 35°C via an LCD microcomputer controller. Equipped with safety devices like high-low pressure protection, it ensures stable and reliable operation. Certified by CE, ensuring compliance with EU safety standards and enabling market access.

Main Specification

Compressor:

(1). All the DARKO water cooled screw chillers adopt world famous brand semi-hermetic screw and semi-hermetic reciprocating compressors, such as HANBELL, BITZER, REFCOM and etc.

(2). Twin-screw 5:6 gear ratio and advanced linear design, low energy consumption and eco-friendly; good performance, low noise.

(3). According to the cooling capacity need, adopt single compressor or twin compressors circuits system; The compressors can automatically run alternately according to the load change, and balance the running hours of each compressor, which greatly prolongs the chillers working life, and the trouble-free running can reach more than 45,000 hours.

Evaporator:

(1). Adopt the internally and externally threaded reinforced tubes.

(2). The inside surface of the copper pipe is threaded, the outside surface of the copper pipe is smooth, so that can ensure the good heat exchange efficient.

(3). The evaporator design running with the latest CAD design technology, CNC production and processing, compact structure , stable performance. And outside insulated with 25mm thick PE insulation, no condensation, less cooling loss.

Condenser:

Copper tubes more thicker and processed into trapezoidal low-assistance tubes to enhance heat transfer capacity. The surface of the copper pipe is smooth, which reduces the water pressure and ieasy to clean and maintain.

Control System:

DARKO has developed a highly intelligent PLC and PC-level computer control system, which can be used for remote monitoring and control. Simple operation, connect with power supply directly, with lower failure, and high safety factor, easy installation. User can set the parameter as real working need, intuitive and reliable; SIMENS PLC is workable.

Protection System: temperature control switch, high and low pressure switch, overload protection, compressor overheat protector, compressor frequent start protector and abnormal indicator light.
