The Quantech QWC4 water-cooled screw chiller has been added to Johnson Controls’ chiller portfolio. It utilizes R-134a refrigerant, which has no ozone-depletion potential.

A chiller system is one that must be hard-wired, moved with equipment (rather than human power) and generally has more than 5 tons of cooling capacity.

Developing an industrial process chiller system for low temperature applications has many challenges, but it can be — and has been — done. This article discusses common challenges and shares insights into research that was used to design a chiller system that operates to -45°F (-43°C) fluid temperatures. 

When modern machines run at higher speeds, they use more energy. This generally results in the liberation of more heat. In most printing applications, excess heat is a problem.

With the launch of the TCX 4-90A chiller range, Atlas Copco extended its industrial portfolio to include process cooling equipment. The company plans to introduce more products to the market in 2021 and extend the range to include higher cooling capacities.

To achieve operational goals, the Glace Bay Miners Forum in Nova Scotia upgraded its ice rink with a custom-designed ammonia chiller system.

A new cannabis cultivation facility in Massachusetts will use two 200-ton Tecochill chillers from Tecogen Inc. The chillers will provide facility cooling using natural gas with the free waste heat utilized for dehumidification.

A chiller that utilizes compressor inverter technology can reduce power consumption up to 65 percent and lower operating costs, says one manufacturer.
