The Centralized Water System Challenge Facing Modern Laboratories
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 spiraling distribution costs (see Figure 1).
CENTRA products provide the laboratory designer with a level of flexibility that is impossible to create with traditional central systems.
Ensuring lab water purity is a priority and is, therefore, a key element in the CENTRA system design. CENTRA systems 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 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.
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 system loop below (using a CENTRA-RDS system), thus extending the distribution system. Alternatively, a new loop can be created using a standalone CENTRA-R 200 system. The CENTRA system 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.
