MetalPro Resources announces that we are now representing South-Tek Systems, manufacturers of a wide range of Nitrogen generators. South-Tek Systems are clever and simple, yet they can save big money (up to 90%!) over the common bulk cryogenic systems used by most manufacturing plants. Unlike those installations, you generate only the amount of gas that you need, so waste is eliminated. Since youâre in control, there are no deliveries to worry about, and no complicated contracts to navigate. And South-Tek Systems can be set up for a range of purity levels, covering everything from the most demanding processes to simpler, "good enough" applications.
