The Benefits of Using a Screw Compressor Chiller

Screw chillers are among the popular types of cooling equipment that use a screw compressor for higher cooling efficiency, making them suitable for industrial applications. They use a refrigeration cycle to eliminate heat from heat-generating applications and processes. A screw compressor chiller has a simple structure with minimal moving parts that are prone to wear, making it durable. The smooth circular motion eliminates the surge phenomenon during low-load operation, which also helps reduce vibration and operational noise.

High-quality screw chillers come in air-cooled and water-cooled types that range from 30 to 900 tons. Reputable manufacturers work with trustworthy companies that make reliable compressors, such as Hanbell and Bitzer. This way, they guarantee an outstanding system design backed by the excellent performance of the components.

There are many benefits of using a screw compressor chiller. Here are some of them:


·         High-quality parts

The best 105KW to 928KW water-cooled and air-cooled screw chillers use Hanbell or Bitzer screw compressors, making them ideal for factory-wide central cooling or large-scale one-to-one cooling. They are equipped with Schneider electric accessories and Siemens Smart Series Programmable Logic Controllers for comprehensive and intelligent monitoring and controlling. PLCs apply RS-485 and PROFINET communication protocols to simplify controlling expansion and make it economical.


·         Easy to use

An advanced air-cooled screw compressor chiller simplifies the operation with a 10-inch touchscreen panel with an intuitive interface that lets operators see the running status at a glance. It produces a detailed unit running status record and detailed alarm information for faster troubleshooting.


·         Reduce downtime and maintenance costs

The heat-exchanging parts of an air-cooled screw chiller feature a generously sized aluminum fin condenser with an epoxy resin coating to reduce vulnerability to ambient corrosion while ensuring a high heat dissipation rate. The shell and tube evaporator has high-quality threaded copper and carbon steel tube to minimize blockage.


·         Advanced compressor technology

A high-quality water-cooled screw compressor chiller uses Bitzer or Hanbell Semi-hermetic screw-type compressors with four-grade capacity control for a smoother startup without affecting the electricity grid.


·         More configurations

Manufacturers offer plenty of configurations to make the screw chiller ideal for your process cooling requirements. These include a built-in hydronic module, a remote panel, a medical- or food-grade water circuit, and a heat recovery module for energy reuse.

Harnessing the Power of Air: Exploring the Working Principle of Air-Cooled Chillers

  Process cooling varies across industries, depending on specific equipment and applications. One type of process cooling equipment is the air-cooled chiller. This refrigeration system cools fluids and operates in conjunction with a facility's air handler system. Unlike systems that use cooling towers, air-cooled chillers rely on fans to expel heat from the building, enhancing their versatility for various operational scales, from small setups to large venues like outdoor malls and theme parks. An air-cooled chiller consists of four key components—a condenser, compressor, evaporator, and expansion valve. Despite housing these complex components, air-cooled chillers are designed to be compact, which makes them easy to install and maintain. Their portability is a significant advantage, allowing for quick setup in emergency situations or at large events. The simplicity of their structure also makes air-cooled chillers easier to operate compared to their water-cooled counterparts. ...
