What 2Plus does

2Plus is a New Zealand-based provider of chemical-free electrochemical water treatment systems for cooling towers, evaporative condensers, and industrial chiller circuits. The company was established in 2015 and operates from Mount Maunganui, Bay of Plenty, with regional sales coverage into Australia and a growing presence in Singapore and Malaysia. Its core product is the DeCalon (DCI) device, which uses applied electro-chemistry governed by a patented intelligent controller to drive non-spontaneous redox reactions that precipitate calcium and magnesium hardness at the cathode and generate biocides at the anode, eliminating scale, corrosion, and biological growth without hazardous chemical dosing. A complementary product, CataGreen, manages micro-organisms using an inhibitor immobilised on fluidised-bed polymer beads and is sold as a recurring consumable with a six-month service life.

The company generates revenue primarily through capital hardware sales of DCI devices into enterprise and industrial sites (hospitals, data centres, food and beverage processors, cold-storage operators, kiwifruit packhouses, plastics manufacturers, and government facilities), supplemented by recurring CataGreen module replacement. Pricing is quote-based and tied to site assessment, with documented customer paybacks under three years and verified energy savings in the 7–19% range and water savings of up to 90% on blow-down. Named enterprise customers include Lakes DHB, Waikato DHB, Digital Realty (SIN10 Singapore), Keppel Land (Keppel Bay Tower), Goodman Fielder, Lineage Logistics, Seeka, Bidfood, Tip Top, EastPack, and Linde / BOC Gases, among others.

2Plus goes to market through a direct enterprise field-sales model staffed by named regional sales managers, supported by independently monitored trial programmes (e.g., Power Solutions Limited at Lakes DHB), conference presence at NZIHE, EMANZ, EECA and Australia's Total Facilities Expo, case-study-driven content marketing, and earned media coverage in trade publications. The company is founder-led by directors Andrew Coker and Gavin Cherrie and appears to be privately held with no institutional funding disclosed beyond a small 2023 Callaghan Innovation grant; growth has been financed organically out of operations across New Zealand, Australia, Singapore, and Malaysia.

Core offering

2Plus manufactures and sells the DeCalon (DCI) electrochemical water treatment device, which removes scale, corrosion, and biological growth from industrial cooling systems and HVAC water circuits without hazardous chemicals, using a patented intelligent controller driving redox reactions. Its complementary CataGreen product manages microorganisms in evaporative cooling systems via polymer-bead immobilised inhibitors, enabling chemical-free water treatment for hospitals, data centres, food processing, cold storage, and industrial facilities across New Zealand, Australia, Singapore, and Malaysia.

Product overview

2Plus offers a portfolio of two complementary water treatment products: the DeCalon (DCI) Device as the core electro-chemical descaling system for cooling water systems, and CataGreen as an add-on module that manages micro-organisms and works in series with the DeCalon system to provide comprehensive chemical-free water treatment for industrial and commercial cooling applications.

Functional benefit

Brands

• DeCalon: DeCalon (DCI) is a revolutionary approach to eliminating scale in cooling water systems. Through applied electro-chemistry and a patented intelligent controller, DCI removes water hardness from cooling systems without the need for hazardous chemicals. The innovation provides a green technology solution to scaling and corrosion in large building HVAC systems and industrial chiller circuits.
• CataGreen

Products and services

• DeCalon (DCI) Device Electrochemical water treatment device that eliminates scale in evaporative cooling systems and industrial chiller circuits through patented intelligent controller-driven redox reactions, removing water hardness without hazardous chemicals. It precipitates CaCO3 and Mg(OH)2 at the cathode to remove scale, generates biocides including chlorine and hydrogen peroxide at the anode, and operates continuously to prevent scale formation. Designed for large building HVAC systems and industrial chiller circuits at hospitals, data centres, food processing, cold storage, and industrial facilities.
• CataGreen Microorganism management system for evaporative cooling systems that functions in series with the DeCalon descaling device. Contains an inhibitor immobilised on fluidised bed polymer beads that damages cell membranes, disrupts intracellular processes, and inhibits cellular fission. Self-regenerating active component with a six-month service life, eliminating the need for hazardous chemical biocides and maintaining legionellae and HCC counts well below mandated target levels.
