What is the Design of a Water-Cooled Scroll Chiller and How Does It Work?

water-cooled scroll chiller is a piece of cooling equipment used in various industrial applications. It provides a cooling effect with chilled water circulation, preceded by several scroll compressors interleaving compression on the refrigerant. A well-designed system works efficiently to reduce your operating budget and boost productivity. Newer models function quietly, making them ideal for sound-sensitive, evaporative condenser, remote air-cooled, and water-cooled applications.

The design and reliability of water-cooled scroll chillers depend on the manufacturer. The best ones don’t require an open and large space for reliable and stable operations, making them ideal for outdoor and indoor installation.

Reputable manufacturers use components from international brands, such as Copeland and Danfoss, for the hermetic scroll compressors and Schneider Electric. So, you’re guaranteed superior performance that won’t fail. Here are more things you should know about the design and function of a water-cooled scroll chiller:


High-quality water-cooled scroll chillers have a cooling capacity range from 9.2KW to 203.8KW and a temperature control range from 5 degrees Celsius to 30 degrees Celsius. The temperature-controlling accuracy is ±1 degree Celsius.

Smart microprocessor controller

The intuitive microprocessor controller simplifies temperature control and monitoring. Users can refer to the English text display or get alerted by an audible alarm for any unusual situations for the process and the chiller. Some chillers come with communication protocol support.

High-quality parts

A premium quality water-cooled scroll chiller is equipped with high-end components from reputable brands, like Schneider, including the thermal relay, contactor, and breaker. This guarantees a longer and more stable service life. Some manufacturers work with well-known compressor manufacturers like Copeland and Danfoss for efficient hermetic scroll compressors.

Heat exchange

The chiller has specially designed and generously sized shell and tube condensers to reduce the risk of obstructions caused by poor water quality. A high-quality brazed plate heat exchanger ensures efficient higher heat exchange.

Hydronic module

The water-cooled scroll chiller has a built-in hydronic module with a large-flow circulation pump and buffer tank to simplify installation and use. Outlet and inlet water bypass valves enable water pressure adjustments as necessary, and the water tank sight glass makes it easier to check the water quality and level.

Optional features

Some manufacturers offer custom features for their water-cooled scroll chillers. They can provide a closed-circuit version if you’re using an external chilled water reservoir or an expansion tank to stabilize water supply pressure. They also offer complete food-grade and medical-grade stainless steel water circuits, dual water circuits, remote control panels, and heat recovery modules. Be sure to check with them for more options.
