Gas panels are used in central gas supply systems for reducing the high primary pressure in the cylinders to more manageable secondary pressures.
Gas panel is the place where the cylinders are changed, etc. It can be considered the heart of the central gas system.
Linde has two types of manual gas panels: single and double. Single panels handle one cylinder or bundle at a time. When the cylinder/bundle is empty it has to be changed. Double panels handle two cylinders or bundles (or a combination) at a time. When the cylinder or bundle is empty, switchover has to be done manually.
S 300 is a single gas panel with diaphragm pressure regulator, especially suitable for non-corrosive gases up to 6.0 purity (99.9999%) as well as gas mixtures with a low concentration of corrosive components. It is designed for single cylinders or bundle and can work up to 300 bar.
S 203 is a panel designed for single cylinders or bundles with diaphragm single-stage pressure regulator, especially suitable for non-corrosive gases up to 6.0 purity (99.9999%) as well as gas mixtures with a low concentration of corrosive components. It is equipped with external gas purging to allow purging of the high pressure side before disconnecting cylinders. It is mounted on a stainless steel console and consists of a pressure regulator, inlet and outlet pressure gauges, a relief valve and shut-off valves for the process gas at high and low pressure ends and for the purging gas.
