2 Page Chapter Title Centra Water is all we do. We know water. We recognize that a fundamental element in designing or upgrading a laboratory is planning space and equipment needs for critical services, such as gases and highpurity water. At ELGA, we have applied our expertise gained from 50 years of innovation in water purification technologies, to design CENTRA, a complete water purification, storage and distribution system packaged into a single unit. The CENTRA design overcomes the limitations of traditional central water purification systems to deliver consistent water purity, flexibility and economy. This brochure outlines the key features of all the products in our CENTRA range that are designed to supply Type I to Type III purified water to everything from glassware washers and autoclaves to high purity polishers such as our PURELAB Ultra and PURELAB flex. Total confidence in your Pure Water system. The CENTRA product family includes a Centralized Recirculating Distribution System and Centralized Purification and Distribution Systems (first purifies and then distributes the purified water). All built in purification technologies are controlled by a central processor with audio-visual alarm warnings, an internal leak detection alarm and connection to building management systems. Prior to installation a dedicated team of ELGA project engineers will work with you to develop a designed engineered solution and for complete peace of mind, every ELGA product is backed by a global service structure, ensuring your system remains costeffective and delivers pure water during its entire life time.

3 Page CENTRA Centralized distribution of pure laboratory water adapting to your applications as they change The CENTRA Advantage Purity This is ensured by vent filtered wrap-around reservoirs, controlled distribution flow rates, and a selected range of purification technologies such as UV photo oxidation, deionization cartridges etc. Simple and easy sanitization processes ensure longterm bacterial control. A choice of purification media solutions is available to optimize inorganic and organic purity. Flexibility Modular design allows a number of CENTRAs to be connected, thereby creating a network of water units for a facility. Purity of water can be adapted to specific laboratory applications and changed as needs develop. A smaller footprint ensures the water purification system occupies less premium plant or laboratory space than conventional installations. Economy Individual laboratory needs can be met separately without requiring the entire building or site to have a higher specification. Maintenance is easier on a smaller system and can be tailored towards the needs of individual laboratories. Faster commissioning and installation time speeds up the build process and helps reduce costs. The table below provides a summary of the CENTRA range and the key features of each product to help you match the best system to your laboratory design.

6 Page Chapter Title Training and education in system design considerations At ELGA we see it as our responsibility to ensure that clients, architects, consultants and contractors are made aware of the complexities when designing new lab services. We hold a range of training courses and seminars that cover detailed loop and system design through to basic awareness of key design issues. For more information contact info@elgalabwater.com. Facility design, build and installation working together for a customized solution We understand the challenges of designing, building and equipping research laboratories, whether you require a complete water purification package for an individual laboratory, a suite of laboratories, or all the laboratories and associated facilities (i.e. washing rooms) in a building. We have provided centralized solutions that have met all specified lab water requirements economically and on budget across a broad range of organizations, including academic research laboratories in universities and institutes, clinical laboratories in hospitals, R&D laboratories in small biotechnology companies and laboratories in major pharmaceutical and biopharmaceutical corporations. Being part of Veolia Water, the world s largest water purification company, gives us the capabilities and resources to provide unsurpassed centralized water purification solutions to either single or entire suites of laboratories in a building, immaterial of the quantities and qualities of purified water and the space available. Our ELGA team works together with architects, consultants, facilities managers, suppliers and scientists to provide help and expertise at all stages from conceptualizing and finalizing the facility design through to the actual build and water purification installation. The design and installation of complete water purification packages depends on a wide range of parameters that include: The specific scientific or clinical applications Feedwater quality Required range of water qualities and compliancy Range of water quantities i.e. peak-usage and normal usage per day or week Space availability Budget

7 Page System Design Your first step to Pure Water: The ELGA LabWater water analysis kit An informed start for a streamlined solution At ELGA we do not speculate or work on assumptions about your water quality. On our first visit to your laboratory we will carry out a test, on site, that analyzes your feed water quality. Armed with data about your laboratory s water quality, required applications, lab design and budget, our sales team will deliver an informed proposal about the best water purification solutions to suit your needs. At ELGA we help you through the entire process of concept, design and implementation of your project. At the very early stages of planning, estimates can be provided for different scenarios without much information from the client. However, as the project progresses we will take you through a water usage assessment. This identifies each point-of-use (e.g. sinks, washers and any local ultrapure systems) as well as the flow rate and volume required for a given period. It is important to identify peak and normal usage per hour, day and week, as well as pressure requirements. This information, combined with distribution loop length and path, will determine not only the overall amount of purified water, but also the most efficient size and type of system (purification, storage and distribution). Using this data, our teams of contract engineers and project specialists will design the most efficient system for your design, using CENTRA modules as well as (if required) other ELGA products or bespoke components. After installation and commissioning, our ongoing tailored service and maintenance support will ensure that your systems are running optimally.

8 Page The CENTRA concept The centralized water system challenge facing modern laboratories Figure 1: A traditional central system. The single centralized system serves labs located on two floors, and takes up a large area in a dedicated plant room. Any usage changes in the labs will require the entire building to be up- or downgraded. There is an increasing requirement for high purity water to support a wide range of research applications. Many research laboratories change their activities with time or need to scale up their current research applications, thereby requiring larger quantities of research-grade water. Laboratory reconfigurations will also change the demands on lab water. This continual need for adaptation to meet changing requirements has led to a more modular approach to laboratory design and architecture. Traditionally, laboratory networks within a building can require larger central systems with very high storage volumes of pure water and powerful (high pressure) distribution systems. This type of design does not always optimize water purity and can lead to spiralling distribution costs (see Figure 1).

9 Page The CENTRA Concept Providing all the support you need The CENTRA solution Products in our unrivalled CENTRA range provide the laboratory designer with a level of flexibility that is impossible to create with traditional central systems. Our application specialists will provide advice and guidance on the most efficient and effective CENTRA solution for your laboratory design. With each CENTRA comes the support and guidance of a global network of project engineers who can ensure that your system design, commissioning and installation runs smoothly. Of course, as with all ELGA solutions, ensuring lab water purity is a priority and was, therefore, a key element in the CENTRA design. CENTRA can incorporate a range of purification options that include: reverse osmosis (RO), UV photo-oxidation, sub-micron filtration, deionization, storage quality control and full system recirculation to match the water quality demands of the laboratory. Figures 2 and 3 illustrate the flexibility and economy of the CENTRA system. Adapting to changing laboratory needs Figure 2: Today s lab water requirements. One lab, located on the second floor, requires a distribution loop. Figure 3: Tomorrow s lab water requirements. An additional laboratory, on the third floor, requires a distribution loop. This can be easily connected to the CENTRA loop below (using a CENTRA-RDS), thus extending the distribution system. Alternatively, a new loop can be created using a standalone CENTRA-R 200. The CENTRA design can be further tailored to suit the activities in the new laboratory. In addition, the CENTRA systems can be interconnected to enable full redundancy, thereby ensuring that in the unlikely event of failure, water is still available. Figure 2 Figure 3

11 Page Inside the CENTRA Issues raised by traditional central laboratory water systems versus the CENTRA solution Purity Economy Flexibility Reliability Traditional central systems Water purity can be compromized as traditional central systems require reservoirs that are susceptible to bacterial contamination. Uneconomical use of space; a single centralized water purification and distribution system typically occupies a large area in a room that is separate from the laboratory (i.e. plant area or washing room). Higher costs if only one or a few laboratories in a building require(s) a high flow rate for their applications, then all the laboratories (e.g. those requiring low flow rate or usage) must have a much larger and more complex purification and distribution design. This often results in higher costs as larger diameter pipework, increased pressure and flow rates are required. Inflexible design; as pure water usage changes between laboratories, central systems must upgrade or downgrade throughout the entire building. If the central system fails, then there is seldom a back-up; therefore, the entire suite of laboratories in a building will not have access to purified water on tap. CENTRA solution CENTRA systems are designed to provide water purity without compromise. The systems are placed close to high flow applications (e.g. large glass washers) and variable speed pumps can control the water flow in the loop to suit individual requirements, thereby eliminating the need for large storage volumes. Compact design allows CENTRA systems to be placed directly in or close to laboratories, thereby occupying less plant room space. CENTRA systems can be placed closer to the applications, saving costs by reducing lengths of pipework and excluding the need for larger diameters and minimizing pressures throughout the entire loop. Modular design allows the optimum flow rate to be delivered separately to individual laboratories, i.e. requirements that range from high flow rate through to low usage can be met with the flexibility of the CENTRA system. CENTRA systems can be interconnected to enable full redundancy, thereby ensuring that in the unlikely event of failure, water is still available.
