  • What is a ton of refrigeration?

    Commercial refrigeration systems in the US are mostly rated in tons of refrigeration and this term is used widely in other parts of the world. However, outside the US, cooling systems may be normally specified in kW (or MW) or in Btu/h. The roots for refrigeration are in the ice making industry, and the ice manufacturers wanted an easy way of understanding the size of a refrigeration system in ...

  • How to Optimize Oxidation Systems for Efficient Operation

    Emphasis on air management within converting-process dryers and ovens is critical to the design of pollution-control systems for treating exhausts containing VOCs (volatile organic compounds). Efficient air management allows the pollution-control system to be optimally sized to meet the needs of the process. Good process control further defines the emission stream by avoiding the need for large ...
