Multiple Effect Still

Mueller Pyropure multiple-effect stills (MES) are the simplest, most reliable means of producing pyrogen-free water-for-injection (WFI) that meets all the U.S. Pharmacopoeia (USP) requirements.

Mueller Multiple-Effect Stills have a simple, robust design that minimizes moving parts.  This design minimizes maintenance and downtime, ensuring that your facility has Water-for-Injection when it is needed. 

We have eleven sizes of units, each with different numbers of effects, ranging from 90 gph to 3,700 gph, to ensure that you can find the right size for your facility. 

Defining Features

• Simple. Reliable. Efficient.
• Our MES is efficient because the system recovers the latent heat of vaporization occurring within its own process to heat feedwater and uses feedwater as its primary source of cooling.
• With absence of moving parts, the PyroPure MES requires less maintenance and is much quieter than mechanical compression stills.
