TECHNOLOGY OVERVIEW SUPPLY BOARDS A supply board is used in a central gas supply system in order to reduce the cylinder pressure to an appointed secondary pressure. The supply board will then supply a stable pressure to line regulators or points of use. A supply board can be considered like a simplified switch over board (without the continuous gas supply from several high-pressure sources). Most of our supply boards have 3 common inlets available. This avoids installation of extensions and increases safety of the installation. Our products exist in raw brass, chrome plated or stainless...

TECHNOLOGY OVERVIEW (continued) SWITCH OVER BOARDS Rotarex switch over boards can make your source management easier. Our first target is to make your installation safer, easier-to-control and to help you improve cost productivity. SAFETY: -- DUOBLOC: 4-6 cylinder connections possible w/o extension - to improve the global system tightness of the process and reduce leakage points. Also, with the DUOBLOC concept you can purge independently each side. The purge can also be collected. -- RELIEF VALVE: all supply and switch over boards are standardly equipped with a relief valve (one on...

TECHNOLOGY OVERVIEW SEMI-AUTOMATIC SWITCH OVER BOARDS A semi-automatic switch over board is a system which provides a continuous gas supply to the piping system. One source of gas is used as the primary source, while a second source is held in reserve. When the primary source reaches a predetermined pressure, the reserve supply automatically begins to supply gas to the system. Once the switch over occurs and primary source is replaced, the switch over board is reset, such that the reserve supply supplying gas is now designated as primary source and the secondary source is now held in...

TECHNOLOGY OVERVIEW (continued) PREMIUM QUALITY FOR BETTER PERFORMANCE All our regulators are designed respecting the EN ISO 2503. The production of the regulator is certified according to ISO 9001. Also external audits from customers help us to improve continually our products. This strategy is also applied on our supplier base which is working very closely with us in order to reach new standards and new performance. In order to fulfil the customer expectations regarding quality, Rotarex implements state-of-the-art quality management practices used in the automotive industry in order to...

TECHNOLOGY OVERVIEW (continued) PRESSURE REGULATOR TECHNOLOGIES Rotarex Supply Panels and Switch over Panels use 3 main pressure regulator technologies to achieve a stable and reliable pressure regulation: BALANCED VALVE -- Best-in-class pressure stability -- Minimizes the effect of inlet pressure fluctuations on outlet pressure -- Increases regulator lifetime and reduces cost of ownership by reducing seat effort -- Diaphragm technology only DIAPHRAGM -- Our most-used technology (cylinder regulation, line, supply panel...) -- Compact design -- Good precision PISTON -- Stable outlet flow --...

TECHNOLOGY OVERVIEW (continued) CARTRIDGE REGULATOR Superior technical performance with cartridge technology: -- Better outlet pressure stability due to the cartridge design. Outlet pressure remains stable despite any fluctuation of inlet pressure. -- Longer product life due to less impingement on the diaphragm. -- Compact design with reduction of dead volume (minimal purge requirements) -- Sintered inlet filter provides better filtration without restricting flow. Fine threads to easily set up the outlet pressure Cartridge Sintered filter Ergonomic hand wheel for pressure adjustment Spring...

SELECTING THE RIGHT SUPPLY SYSTEM To choose the right supply solution for your application and get the best results, you should identify the following technical parameters: TECHNICAL PARAMETER Gas Purity Nominal inlet pressure Nominal outlet pressure Nominal flow (N2) Single stage or dual stage ? EXAMPLE Inert, flammable, oxidizing, corrosive, toxic UHP, HP, industrial, medical, diving Bar or psig Bar or psig Nm3/h, Nlpm, Slpm or SCFM Dual stage or BV Technology are needed where pressure stability is essential Regulator, point of use, supply board, switch over board Brass, chrome plated...

Most Rotarex Supply and Switch over Boards are available in stainless steel 316L or chrome plated brass, and on some models, raw brass or aluminium. Which material is best for your installation? Stainless steel 316L: The recommended option for corrosive gases and high-purity applications due to its superior resistence, non-reactivity, exceptional durability and high-surface finish properties. It is compatible with most gas types and low-velocity oxygen applications. Rotarex uses stainless steel type 316L, an austentic chromium nickel stainless steel containing Molybdenum. It offers: -...
