Puretech’s innovative OASYS™ is a chemical sanitisation system that provides a single source solution for taking raw water to purified water complying with all relevant pharmacopeia standards.

The OASYS™ has been developed to complement GENESYS™. It is a chemically sanitised version of the GENESYS™ with a simpler GAMP 4 compliant control system. The unit can be validated up to USP and EP standards with a full FAT being carried out at our works.

Puretech engineered and installed a purified water to system at the AstraZeneca Research and Development Centre, Cambridge , taking raw water from the mains through purification using OASYS™ units. The purified water, which is stored in a 5000-litre tank, is distributed via a stainless-steel ring main to user points in the laboratories.
