Custom-made reliable and hygiene solutions for pharmaceutical water storage
What is a WFI storage tank?
A WFI storage tank is a purpose-built storage vessel designed to hold Water for Injection – an extremely pure type of water used in the pharmaceutical and biotechnology industries. WFI is primarily used in the production of medicines that are administered as injections or infusions. WFI is produced by distillation or reverse osmosis, followed by additional treatment, it must meet the strict requirements of pharmacopeia standards such as USP (United States Pharmacopeia) and EP (European Pharmacopeia). The requirements for storing this ultra-pure water are extremely high. Stainless steel WFI storage tanks are essential and reliable solutions for ensuring maximum hygiene and sterility in pharmaceutical manufacturing.
Designed for maximum hygiene
In injectable drug production, contamination-free water storage that complies with international guidelines is essential, since patient health depends on it. Our WFI storage tanks are engineered to deliver maximum safety, process reliability, and long-term performance. These tanks combine premium materials, advanced monitoring systems, and complete documentation to integrate smoothly into pharmaceutical processes, ensuring both efficient operation and sterile conditions.
