Ensure the Highest Quality with Our Purified Water Systems

Purified water is essential in the pharmaceutical industry, playing a vital role in drug production, quality control, and equipment sterilisation.  NSI Mobile Water Solutions provides advanced purified water solutions with fully hot water sanitizable, skid-mounted systems. These multi-technology systems deliver high-performance purified water for the pharmaceutical industry in a sustainable way, meeting USP and Ph Eur purified water quality standards and complying with FDA, cGMP, and GAMP requirements.

Cold Water for Injection (Cold WFI)

Cold Water for Injection (Cold WFI) is a high-purity water produced using advanced cold-processing technologies like Reverse Osmosis (RO), Continuous Electrodeionization (CEDI), and Ultrafiltration (UF). These systems meet stringent microbial and endotoxin standards without the need for distillation, offering lower operational costs and a smaller footprint. Widely used in pharmaceutical manufacturing, biotechnology, cosmetics, and medical device industries, Cold WFI is ideal for processes requiring sterile, high-quality water. Modern systems also feature biofilm control and hot water sanitizable membranes, ensuring long-term reliability and compliance.
