Pure Steam Condensing System

Our PyroPure condensing systems are the perfect element for companies looking to use their pure steam generating systems for the production of water-for-injection (WFI) quality pure steam and WFI quality distillate. Easily change the game by adding our condensing unit to your pure steam generator and get the best of both worlds.

The terms pure steam and clean steam are often used interchangeably in the pharmaceutical industry. However, not all equipment marketed as clean steam generators are up to the task of producing WFI quality pharmaceutical pure steam. Paul Mueller Company pure steam generators use a tangential nozzle to provide separation of impurities from incoming feedwater, producing pyrogen-free steam that, when condensed, meets USP requirements for water for injection.

When used with a PyroPure pure steam generator or when fed WFI quality pure steam from another source, the water produced will be pyrogen-free and will meet or exceed the latest specifications of the USP for water-for-injection (WFI). The optional stand-alone design for the condensing system allows it to be installed adjacent to a pure steam generator or located remotely at point of use.
