The Next Generation of Ambient WFI / PW is Here!

Membrane-Based Reverse Osmosis Water for Injection (WFI) and Purified Water (PW) Systems

Ambient Water for Injection (WFI) & Purified Water (PW)

The TORRENT™ WFI Packaged Membrane WFI System and TORRENT™ PW Packaged RO/CEDI USP PW System generates compendial water that exceeds current USP, PhEur, and JP requirements for direct and contract manufacturing of critical pharmaceutical, biopharma, medical device, cosmetic, and personal care products. The fully integrated systems are a part of a complete Aqua-Chem water room solution that includes utility pretreatment, generation, and hot or ambient storage and distribution.

TORRENT™ continues Aqua-Chem’s legacy of innovation in WFI with a standardized triple-membrane barrier that is used to deliver water free of microbes and endotoxins at ambient temperatures and ensures maximum quality with minimal risk. All TORRENT™ water systems are engineered for performance and reliability using only non-proprietary, premium components including Mettler-Toledo instrumentation, Bürkert valves, and IonPure® CDI-LX™ modules. The novel form factor improves ease of use, includes fully-automated operation and hot water sanitization, and is fully factory tested for fast installation, start-up, and qualification.
