Yes, vapor compression can produce both hot or cold USP Purified and WFI water. In many instances, vapor compression is the most cost effective solution for USP Purified water production.

Yes, because Vapor Compression stills run at a relatively low temperature and pressure (1.5 psig and 218 degF), the soft scale formation seen on Multi-Effect Stills is not a consideration. Multi-Effect Stills will form soft scale from other constituents in the feed water due to the elevated temperatures (300 degF).
