What Chlorking does

ChlorKing, Inc. (operating as Chlorking) is an Atlanta, Georgia-based manufacturer of commercial aquatic water treatment equipment specializing in on-site electrolytic chlorine generation and ultraviolet light disinfection systems. Founded in 1999 by Steve Pearce and chemist David von Broembsen (whose 1970s membrane-based electrolytic chlorine prototype underpins the company), ChlorKing targets commercial swimming pools, water parks, aquatic facilities, spas, and industrial disinfection users including agriculture and food processing. Its product portfolio includes NEXGEN on-site chlorine generators (the first commercial system to produce pH-neutral chlorine using pool water as source water without salt addition), CHLOR (SM) commercial salt chlorinators delivering up to 28 lbs of chlorine output per single cell, Sentry UV ultraviolet systems NSF/ANSI-50 certified for supplemental and secondary disinfection (including 3-log Cryptosporidium parvum inactivation), and the HYPOGEN / HYPO MINI line of hypochlorous acid generators for industrial disinfection. Additional product lines CGEN and CLOROGEN are in active development.

The company operates a sales-led go-to-market model through a dedicated North America sales team, an International Water Division for global markets, and a network of direct sales contacts, supported by a technical resources library. Revenue is generated through three streams: equipment sales (hardware), a recurring replacement parts business (cell stacks, quartz sleeves, TDS controllers, and accessories), and Equipment Supply and Maintenance Programs that bundle equipment lease, delivery, and ongoing maintenance into a fixed monthly payment. Pricing is quote-based and not publicly disclosed; the leasing/maintenance program broadens accessibility to mid-market operators without large upfront capital. The company maintains an install base of more than 15,000 commercial swimming pool and water park installations worldwide.

Following the 2024 acquisition by Hayward Holdings, Inc. (NYSE: HAYW), a global pool equipment manufacturer, ChlorKing operates as a wholly owned subsidiary, contributing approximately 2% to Hayward's Q2 2025 net sales of approximately $300 million and gaining integration into a broader pool equipment and outdoor living distribution platform. Founder Steve Pearce continues as Co-Founder and Group President & CEO, and Sentry UV remains a wholly owned acquired brand within the portfolio.
