Pristill manufactures water purification systems that use its patented Centrifugal Vapor Distillation (CVD) technology, originally developed for NASA’s International Space Station, to produce ultrapure water for industrial, semiconductor, and high‑salinity reuse markets. The devices achieve 99.99% contaminant removal—including bacteria, radiological materials, PFAS, and dissolved gases—while consuming only 10 Wh per gallon, delivering up to 99.3% greater efficiency than conventional distillation and significantly lower energy use than reverse osmosis.

Problem
Industries such as semiconductor manufacturing, medical facilities, and high‑salinity water reuse require water that meets stringent purity standards (Type I, II, WFI) while removing a wide range of contaminants, including PFAS, microplastics, and radiological materials. Conventional purification methods—reverse osmosis, vapor‑compression distillation, and multi‑stage filtration—consume large amounts of energy and often cannot achieve the necessary contaminant removal levels.
Solution
Pristill offers water purification systems based on its patented Centrifugal Vapor Distillation (CVD) technology, originally developed for NASA’s International Space Station. The rotating boiler‑condenser creates centrifugal forces that keep contaminants away from the evaporation surface, enabling efficient separation of water vapor from dissolved solids and organics. Integrated self‑cleaning mechanisms prevent scaling, allowing continuous operation on highly contaminated feed streams. The process achieves 99.99% purity, removing bacteria, radiological isotopes, PFAS, micro‑ and nanoplastics, and a broad spectrum of inorganic and organic pollutants. Energy consumption is only about 10 Wh per gallon (≈2.6 kWh/m³), roughly 93% less than traditional vapor‑compression distillation and comparable to or lower than reverse osmosis. Pristill provides three product lines—Standard, Ultrapure, and High‑Salinity Pristillers—tailored to specific market purity requirements and source water conditions.
Target Audience
Primary customers are semiconductor fabs, pharmaceutical and medical manufacturers, and industrial facilities that need ultrapure or high‑purity water, as well as utilities and plants seeking energy‑efficient desalination and high‑salinity wastewater reuse solutions.
