CENTRA RDS
The CENTRA-RDS is a storage and recirculating distribution system designed to work with other CENTRA or PURELAB systems or existing purification installations.
In addition to storing and distributing pure water, the CENTRA-RDS maintains and improves water purity. The CENTRA RDS stores, controls and distributes pre-purified water throughout a building, or a suite of laboratories, via a loop system.

"We had been spending a lot on consumables from point of use systems across our laboratory. It took our time to replace consumables regularly too which impacted on our workflow. By having a centralised system we removed all of those issues, it has made our lab so much more productive."

Features
- Delivers up to 30 liters per minute of type I, type II and type III water from a distribution loop
- Up to 18.2 MΩ.cm, type I, type II and type III water suitable for general and analytical applications
- Bacterial specification <5 CFU/ml is maintained using a combination of technologies
- Reliable continual supply of pure water using unique access controls and leak detection system with optional building management system (BMS) connectivity
- Designed to operate with other ELGA LabWater systems or existing purification installations
- Compact design provides more flexibility for new buildings and refurbishments.
- Full service and validation support

Consumables

Increase in airborne contaminants and potential recontamination of purified water

High levels of organics and inorganics remain in the water reducing the functional life of the DI pack

Reduced flow-rates and bacterial specification will not be maintained

Chlorine, chloramine and organics remain, increasing the burden on downstream consumables which will need more frequent and expensive changes

Uncontrolled bacterial contamination and TOC levels are not reduced

FAQs
- What is the CENTRA RDS?
The CENTRA RDS is a purification system designed to feed a whole building from a plant room. It type 1 ultra pure water or simply distributes RO quality feed water. The difference between a CENTRA RDS and a CENTRA R200 is it does not have an RO so water supply is only limited by pre-purified volumes being distributed to it. Its 200m loop can cover multiple floors or multiple laboratories on a single floor to provide a truly centralised solution. The CENTRA saves space in comparison to competitive products by having an integral 350L reservoir to significantly reduce its footprint.
- Most water purifications systems have a limited make up rate. Is this the case for the CENTRA RDS?
No, the RDS is designed as a distribution system for pre-purified water. This means the only limitation is the amount of water you are able to feed into the RDS.
- How does the CENTRA R200 get type 1 water?
The CENTRA uses an SDI cylinder with a mixed bed resin to remove Ionic content and produce type 1 water.
