CENTRA RDS

Part Number: CNXXXRDM1-230

Quick Overview

The CENTRA has revolutionised the way that large volumes of pure water are produced, stored and distributed. Instead of a central lab system, comprising of an untidy grouping of components and pipework, you can now have just one integrated system box. 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 compact design provides more flexible installation options for new buildings and refurbishments. The CENTRA's small footprint means that it can be placed closer to the laboratory, avoiding the negative cost and design implications of long pipe work loops




Reliable, continual supply of pure water using unique access controls, leak detection systems and full AV alarms with optional building management system (BMS) connectivity



Optimized inorganic water quality through use of in-line purification technologies. Recirculated water is UV treated, filtered and (if fitted) can be improved through deionization



350 l reservoir of purified water available at up to 30 l/min from a distribution loop. A wide range of water purities are possible from RO permeate up to 18.2 MΩ-cm Type I purity



Low microbial counts achieved through vent filtration, spray-ball water distribution and smooth internal surface in the reservoir combined with UV oxidation and 0.2 μm filtration in the loop
