Chillers are used in many applications where chilled liquid is circulated through process equipment. This course will look at different types of chillers used to cool materials, products and machinery, including portable chillers and designs used in 3D printing to cool lasers. It also will explore how some portable chillers use variable-speed compressor technology to provide better efficiency.

Creating energy-efficient chiller systems
With proper design, appropriate chiller features and targeted maintenance, it is possible to establish an efficient chiller system. Simply being conscious of energy considerations and incorporating them into the design can significantly reduce the energy consumption of a chiller system.

Insights into advanced steam turbine centrifugal chiller technology
With a stable supply of low cost natural gas in the United States, steam-turbine-driven chillers are becoming a popular choice, particularly for large combined heat and power (CHP) applications. Steam-turbine-driven chillers also are attractive when the cost of steam is relatively low compared to the cost of electricity. Boilers sized for winter heating can be put to work efficiently year-round when used to generate steam for summer cooling.

Refrigeration 101: Understanding process chillers and their role in industrial settings
Industrial refrigeration is used in many industries, from food processing, chemical, pharmaceutical and plastics manufacturing to construction. Within these industries, water-cooled chillers play an important part in processes that require the cooling of a large amount of water. While they are efficient and last a long time, water-cooled chillers typically are more expensive due to the maintenance required.

Choosing a chiller for laser cooling
For most industrial lasers, adding a process chiller to the layout will help to mitigate the issue of excess thermal energy. The type of chiller chosen influences the integration process and the heat-removal method. Right away, users must decide whether an air-cooled or a water-cooled chiller is best.

5 considerations when choosing a chiller for 3D printing
A recirculating chiller is commonly used to provide liquid cooling to the lasers found in many 3D printers, especially direct-metal laser sintering (DMLS) machines. It is important to pair an appropriate cooling system with a 3D printer to ensure that both systems function properly and reliably for many years.
