A ‘Process’ application, is one where it’s all about controlling the contents of a vessel, pipeline, or chamber. What is the gas makeup inside the vessel? How much of it is in there? All means to control a chemical and/or thermodynamic reaction so that we add value to some base ingredients to convert them into a marketable product.
Electronics applications typically run their tooling requiring Process Vacuum based on differential pressure from barometric; that is, they control their PVAC pumps to “Inches of Mercury Vacuum”. This is because the parts and pieces being manipulated by vacuum are of certain sizes, shapes, and weights. If the differential pressure across the part is not great enough, then the tooling will fail and result in a loss of product, adverse impact to quality, and production downtime.
