6 6 introduction Technology overview Supply boards A supply board is used in a central gas supply system in order to reduce the cylinder to an appointed secondary. The supply board will then supply a stable 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- 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 steel. The installed regulators are coming from our standard product range.

7 introduction 7 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 safety relief valve (one on semi-automatic version, 2 on fully automatic version). -- INVERTER (full automatic)/bypass DESIGN (semi automatic): Its design avoids gas flow into the other side. -- Dedicated gauges (HP and LP). Contact gauges could also be mounted in order to connect to an alarm box. -- With installation of a gas monitoring system, you can easily check your gas consumption from your desk. EASE OF HANDLING: -- Easy access of purging and isolation valve. -- Easy installation with all components pre-mounted on an Omega plate. -- All components for service are easily accessible. LOWER OPERATING COSTS: -- A continuous gas supply to the process means less production interruptions or unplanned disruption to change gas cylinders. -- Larger cylinders together = fewer cylinders = lower rental charge, less transportation charge, better cylinder management. -- Grouping all cylinders in one location means also space saving in production area or in lab which are very expensive surfaces. Manual switch over boards A manual switch over board reduces the cylinder to an appointed secondary and insures gas supply from different high sources. It ensures a safe cylinder replacement. When one high- supply source is in service, the other is in reserve. When the service source is empty, the operator must change the service side to the reserve side manually when changing the empty cylinder

8 8 introduction 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, 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 reserve. The empty cylinder can be replaced without interrupting the gas flow. Automatic switch over boards An automatic switch over board switches automatically, when the service source is empty, to the reserve source and does not need to be reset to allow reversal of the cycle. A switch over board will reduce the cylinder to an appointed secondary and will insure continuous gas supply from several high- sources. This reduces the need for continuous operator monitoring and ensures a safe cylinder replacement. When one high- supply source is in service, the others are in reserve. When the service source is empty, the switch over board switches automatically to the reserve source for a continuous gas supply to the process at the same. The empty cylinder can be replaced without interrupting the gas flow. How to choose between SEMI-AUTOMATIC and FULL AUTOMATIC WHEN SEMI-AUTOMATIC : -- For small installations with low gas consumption -- When the process is not sensible to drop after the switch. -- When you want to change the cylinders at each switch. WHEN AUTOMATIC : -- When the process needs stable delivery of outlet (P2). -- When the installation has a huge gas consumption. -- When using bundles. -- When safety is paramount > reduction of operator presence. -- When less external intervention is desired for better productivity. -- For supply installations far away from the process.

9 introduction 9 technology overview (continued) premium quality for better performance All our regulators are designed respecting the EN ISO 253. The production of the regulator is certified according to ISO 91. 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 stay Best In Class. During the production of your regulator we have several control steps in order to provide you the best quality: -- Supplier Audit in order to control that they fullfill our standards -- 1% cleaning of all parts to O2 standards -- Steaming of some specific components -- Measurement control of parts coming from the production -- 1% Helium leak test -- 1% functional test Most of the supply and switch over boards produced by Rotarex are designed for applications with gas purity up to 6. with a leak rate of 1-8 mbar l/s of helium. Flow measurements Flow curves are based on the ISO EN 253 Norm. The nominal flow are specified for the nominal inlet with the regulator set at the nominal outlet. The outlet flow will then decrease when the regulator is set at a lower outlet than the nominal one. For specific application, do not hesitate to contact us to get the exact flow at the wanted values. Service In order to prevent possible contamination, we recommend that the operator performs a purging after the cylinder change. This maintenance step will help remove moisture, air and other impurities from the system before introduction of gas into the process. This maintains a constant purity in the circuit. For some products like our supply/ switch over boards, it is recommended to perform an annual maintenance in order to prevent wearing of some components. Our customer service team remains at your disposal to supply special spare parts. Safety All products are tested under and also leak-tested before shipment. Our high regulators are also equipped with safety relief valves in order to prevent any damage of the regulator. It is also possible to collect the purge on our equipment in order to avoid any gas dispersion in the atmosphere when using toxic gas. Important notice: the safety relief valve fitted on our regulators will only protect the regulator in case of accident and cannot be used to protect the down stream process. When it is needed to protect the down stream process, use a CE safety relief valve on the pipe work.

10 1 introduction technology overview (continued) regulator technologies Rotarex Supply Panels and Switch over Panels use 3 main regulator technologies to achieve a stable and reliable regulation: BALANCED VALVE -- Best-in-class stability -- Minimizes the effect of inlet fluctuations on outlet -- 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 -- Used for regulator where the outlet is close to the inlet balanced valve technology Our Balanced-Valve Technology regulator gives you dual stage regulator performance in a single stage design. Due to its proprietary design, it is able to balance the internal forces within the regulator and compensates for the fluctuation on the inlet. It provides a constant outlet like a dual stage regulator but with a lower total ownership cost. Switch over boards equipped with this technology don t need any line regulator afterwards and can be connected directly to the application.

13 introduction 13 SELECTING the right supply system (continued) body materials 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: -- Exceptional corrosion resistance - particularly against sulfuric, hydrochloric; acetic, formic and tartaric acids, acid sulfates and alkaline chlorides -- resistance to pitting from chloride-ion solutions -- outstanding strength even at elevated temperatures Chrome plated or Raw Brass: The most commonly used material for industrial and high velocity oxygen applications due to its cost effectiveness versus stainless steel, good strength, resistence and low-friction flow properties. Need more information? You can find more detail about optional, materials on our website. Additionally, one of our material engineers would be happy to discuss the pros and cons of each option to help you choose the best solution. Gas Compatibility: Make sure the body material is compatible with the gas type you will be using. Consult the gas compatibility reference chart on page o-ring materials For many regulators, a choice of O-ring materials is available: EPDM: Ethylene Propylene Rubber NBR: Nitrile Butadiene Rubber FPM: Fluorocarbon Rubber Gas Compatibility: Make sure the O-ring material is compatible with the gas type you will be using. Consult the gas compatibility reference chart on page 64. Inlet/outlet s Different models are designed for different inlet and outlet performance.
