Automated Pure Water
About
Automated Pure Water (APW) is a manufacturer of residential and light commercial water treatment components, originally founded by Jerry Bechtold and acquired by Nelsen Corporation in 2019, with products now distributed under the APW-Nelsen brand. The company's flagship product is the Model 400 Non-Electric Chemical Feeder, a gravity-operated dosing system that uses dry chlorine pellets and water pressure differentials rather than electricity, making it suitable for well systems and off-grid installations up to 75 psi. The feeder features no moving parts, corrosion-proof construction, fully adjustable metering, and carries a three-year warranty. APW also manufactures mineral extractors in six styles with proprietary tank adapters; sand traps in multiple configurations for pre-filtration sediment removal; patented saturation-type chemical mixing retention tanks in nine sizes for contact time in water treatment; and single and twin-chambered ChemMixers (static swirl mixers) for in-line chemical blending. Their Noryl in/out heads come in 3/4-inch to 1-1/2-inch sizes with upflow and downflow configurations using proprietary O-ring distributor dimensions, serving as critical connection components in residential softener and filter tanks. Additional products include tank adapters compatible with Culligan and Ecowater systems, media loaders for resin and media replacement, auto flush valves, and a full line of chemical feeder replacement parts. The complete APW catalog comprises 63 items distributed through Nelsen Corporation's website.
