Air Cooled Inverter Screw Chiller Export to Kenya for Plastic Factory

2022/03/09

On Mar.8th, we, Eurostars, loaded an air cooled inverter screw chiller into a 40 feet container successfully.

This chiller will be delivered to Kenya for plastic industry cooling purpose.

The factory wants to equip industrial chiller for their 2 HDPE 300kg per hour lines and 2 PPR lines 300kg, total 1200Kg, they have a tank with 75 meters cubic, required chilled water outlet temp. 12℃, ensure enough cooling efficiency, working ambient temp. maximum is 25℃. Bitzer compressor is prior choice, and to save energy, they prefer to VFD(variable frequency driver) with Siemens PLC controller.

 

Considering inadequate water source at client’s factory location, and easy installation, we suggest air cooled screw chiller, and as it is low ambient temp., we adopt fan condensing pressure switches for axial fans, and suggest INVT branded VFD, with frequency range 25~50HZ, with Siemens PLC touch screen controller, Siemens control module. We calculate chiller cooling capacity based on plastic weight, plastic type, plastic injection temp. and mounding temp., specific heat, safety factor, etc.

Eurostars variable frequency air-cooled screw chiller adopts enhanced air-cooled variable frequency compressor, which has the advantages of stable and reliable operation, high efficiency and energy saving, not easy to wear, low failure rate, long life, good performance, small vibration, strong resistance to liquid strike and convenient maintenance. This series of products have many advantages, among which the main advantages are reflected in the following aspects.

 

1. Wide Adjustment Range

Frequency conversion chiller adopts airborne frequency conversion drive technology, adjustment range: 20HZ-80Hz, wide adjustment range.

2. Increase the Heat Transfer Efficiency by More than 15%

The variable frequency air-cooled screw chiller is equipped with self-produced high-efficiency finned tube type heat exchanger and adopts new hydrophilic aluminum foil, which can make the condensate water not easy to form water bridge, ensure the heat dissipation and heat transfer smoothly, not easy to scale, high reliability, and the heat exchange efficiency is more than 15% higher than the same type of machine in the industry.

3. Large Refrigeration Capacity and High Energy Efficiency

Frequency conversion air-cooled screw chiller adopts PLC intelligent control system, the single unit has large refrigeration capacity, more accurate outlet temperature and high energy efficiency, which can be widely used in shopping malls, hospitals, hotels, factories, office buildings and other different types of buildings.

 

4. Remote Control System

The chiller is controlled by microcomputer and can be highly integrated through centralized management system. Chiller equip with remote management program, feedback system running information, remote service.

 

5. Safe and Reliable

The chiller has a variety of safety protection measures to ensure the normal operation.
