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.
