What is China High-Efficiency Water-Cooled Screw Chiller and Why Do We Use Them?

The series water-cooled type chiller adopts an efficient semi-closed screw compressor. the compressor adopts a 5:6 asymmetric high-efficiency screw rotor, which is graded or steplessly energy regulated. It is automatically adjusted according to load changes and is more energy efficient. The unit heat exchanger adopts a high-efficiency heat exchange tube to improve refrigeration efficiency, and the unit is equipped with multiple protections to make the unit operate safely and reliably.

Huateng supply professional and honest service.

(1) The water-cooled screw machine is generally an open upper and lower structure of the chiller. Simple structure, fewer moving parts, convenient installation and debugging, reliable operation, low cost;(2) the single machine has large cooling capacity and high volumetric efficiency;

(3) the cooling capacity can be a step-less adjustment.

This water-cooled screw chiller can be used as the cooling system for large commercial buildings, office buildings, factories, power plants, chemical plants, steel plants, hospitals, schools, shopping centers and production processing.

FAQ：

Screw chillers are a common choice in various industries that need a dependable solution for process cooling. These types of chillers, known as vapor compressor chillers, use a screw compressor to circulate the coolant within the system. While there are air-cooled screw chillers, the water-cooled version is more prevalent in many industries, especially those in need of small- to medium-scale cooling solutions.

A water-cooled screw chiller offers advantages such as consistent and quiet operation, low maintenance expenses, space-efficient installation, and enhanced energy efficiency. It's also suitable for use in high-rise buildings.

However, reaping these benefits is contingent on the chiller's design and manufacturing quality. This is why it’s crucial to work with a well-known and skilled manufacturer of industrial cooling solutions so you can secure top-quality water-cooled screw chillers that deliver on the promised features. Leading manufacturers stand behind their water-cooled screw chillers, ensuring they provide these benefits and more:

Rational design and first-class configuration

With a solid internal and external structure, a high-quality water-cooled screw chiller is guaranteed to run on a strong foundation to ensure stable performance all the time. Manufacturers choose parts only from top brands, like Siemens for the programmable logic controller and Hanbell or Bitzer for the semi-hermetic screw-type compressor. Moreover, they take the time to test and verify every component before including it in the chiller. They apply an established production process to ensure reliable pipe connections, welded parts, and other critical aspects of the chiller.

Satisfaction guaranteed!

High-quality water-cooled screw chillers undergo strict quality control to ensure a high-performance and reliable process cooling solution for every application. Additionally, many configuration options are available with specialty parts like an integrated hydronic module, stainless steel water circuits, a heat recovery module, and a remote control panel to meet specific requirements.
