VPure 4400H

The VPure 4400H is a value engineered, Automatic Hot Water Sanitizable, RO/EDI system, designed to meet or exceed current USP, EP and JP Purified Water requirements. All internal wetted construction materials are compatible with Hot Water at up to 85 ˚C (185 ˚F), and it can undergo periodic  periodic cleaning and decontamination with approved chemical sanitizers, acid and base chemical cleaners.



The VPure 4400H is a compact, packaged RO/EDI, USP purified water system with integrated storage and delivery. This feature-packed system efficiently generates, stores, and distributes purified water to the client's distribution loop. It incorporates an electric heat exchanger for user-defined hot water sanitisations, an air compressor to enable smart operation, and pneumatic modulating valves designed for energy and water savings, to align perfectly with your company's sustainability goals.

Packaged RO/EDI USP Purified Water system with Integrated Storage & Delivery System


The Science of Possibility
VPure meets current internationally recognised USP, EP, and JP requirements for purified water. Stilmas’s refined FAT, IQ / OQ, and SAT documentation packages, combined with site implementation support, ensure the quickest path from PO to PQ.
The Science of Possibility
This system offers automatic, independent, or combination scheduling of hot water sanitisations at up to 85°C (185°F) for the generation, storage or delivery system.
The Science of Possibility
The integrated package design of the VPure translates into a compact footprint, designed to maintain proper loop flow velocities and ensure optimum energy efficiency.

Technical description

The VPure system accepts pre-treated potable water, pumps it through reverse osmosis membranes, and enhances conductivity with electrodeionisation. The purified water can be then sent to an optional Ultraviolet steriliser and final filter before storage, or recycled to the system break tank. This ensures high-quality water for purified applications.
