The Tannin Guys Water Treatment Network

What The Tannin Guys Water Treatment Network does

The Tannin Guys Water Treatment Network is a private, for-profit international network of water treatment experts operating from Longueuil, Quebec, Canada, under parent company TGWT Inc. Founded in 2014 when TGWT partnered with Germany's Korn GmbH, the network distributes purified tannin-based water treatment chemistry derived from sustainable plant sources (tree bark). Its portfolio addresses steam boilers, closed-loop heating and cooling systems, cooling towers (COOLTASTIK), and aluminum boilers (TG 3304 PM2 and a Patterson-Kelley-co-developed program), with the single multi-functional plant-based product replacing conventional hazardous chemicals such as sulfites, caustics, amines, phosphates, phosphonates, and polymers. The company positions these products as delivering up to 5% lower GHG emissions, 20% lower water consumption, and 80% lower wastewater discharge, with blowdown rates as low as 0.5% versus typical 5-20% in conventional programs.

The business operates a hybrid revenue model combining product sales (purified tannin chemicals), recurring software revenue via the CLOZIT online mass balance and energy analysis platform (with separate modules for water treatment professionals and plant managers), and technical services including monthly on-site visits for enterprise clients. Pricing is quote-based annually with no capital investment required for adoption. Go-to-market runs through an international member network of regional water treatment experts and distributors, supplemented by direct corporate office handling of enterprise and distributor inquiries. Primary customer segments are hospitals and healthcare facilities, industrial plants, and institutions globally; a documented multi-year case study with CHUS Hospital (Centre Hospitalier Universitaire de Sherbrooke) reports $288,647 in cumulative savings over 10 years, 12.2% water reduction, and 75.7% less boiler blowdown waste. The company also holds a 2019 Écotech Québec Eurêka! Award for sustainability and maintains registered trademarks including The Tannin Guys®, Tanntastik, Cooltastik, CLOZIT, and TGWT.

Core offering

The Tannin Guys Water Treatment Network sells plant-based purified tannin water treatment chemistry and programs for industrial steam boilers, closed-loop heating/cooling systems, and cooling towers. The single multi-functional product acts as a scale and corrosion inhibitor, oxygen scavenger, dispersant, and condensate treatment, replacing multiple hazardous conventional chemicals. The network also offers the CLOZIT online energy analysis platform and ongoing technical service (monthly on-site expert visits) through its international member network.

Product overview

The Tannin Guys Water Treatment Network is an international network of water treatment experts offering purified tannin-based solutions for industrial water systems. The portfolio includes three core product lines: (1) Purified Tannins for Steam Boilers, (2) Purified Tannins for Closed-Loop Heating/Cooling Systems, and (3) COOLTASTIK for Cooling Towers. Additionally, the Clozit digital platform provides online energy analysis tools with two modules: Clozit for Water Treatment Professionals (sales management) and Clozit for Plant Managers (operational analysis). The company also offers a specialized Aluminum Boiler Water Treatment Program developed with Patterson-Kelley. All products leverage plant-based, environmentally responsible chemistry as alternatives to traditional toxic chemical treatments.
