Before the holidays we talked about how vacuum-pump oil becomes contaminated. It is now time to talk about how to overcome this problem using gas ballasting – how it is performed, its advantages and limitations.

The Metal Treating Institute (MTI), media partner Industrial Heating and over 30 sponsors are pleased to announce another record-breaking crowd for the Furnaces North America trade show and conference (FNA 2016).
The January 2017 issue of Industrial Heating features our cover story on a horizontal quench system, the importance of materials science in failure analysis, a new quarterly column, Academic Pulse, and much more.
