EEC Movie This short video shows how Elgressy EEC (electrocoagulation) treats water and wastewater without chemicals. What is electrocoagulation? In an EEC reactor, a DC current passes through the water between metal electrodes. This creates coagulants directly in the water, which bind suspended solids, silica, oil and heavy metals into flocs that are then separated. […]

New project SCG – Kraft In September 2020 we completed and commissioned an Elgressy EST system for the cooling towers of SCG Kraft in Kabinburi, Thailand. The system has been performing very well since start-up. The result: 78% less blowdown Blowdown (drain) Before, with chemical treatment about 45 m³/day After, with EST about 10 m³/day […]

Eagle Cement – Philippines EST+EEC In 2017 we installed a combined Elgressy EST and EEC system at Eagle Cement in the Philippines to remove both calcium and silica from the cooling water. Why two technologies? EST (Electrolysis Scale Treatment) removes calcium hardness as solid scale, preventing scale in the cooling system. EEC (Electrocoagulation) removes silica […]

Olympia Towers Bangkok installation In 2017 we installed an Elgressy EST chemical-free water treatment system on the cooling towers of Olympia Thai Tower in Bangkok. Olympia Thai Tower was one of the first buildings in Thailand to use this electrochemical technology. What the client says “More important is your full support and guidance with high […]

United Nations Bangkok installation In 2013 we installed an Elgressy EST chemical-free water treatment system on the cooling towers of the United Nations building in Bangkok. More than ten years later it is still running and is one of our main reference sites in Thailand. The site Chiller plant of about 900 TR (594 kW […]

Isuzu EST installation In 2018 we installed an Elgressy EST chemical-free cooling water treatment system at Isuzu in Bangkok, Thailand. The system replaces chemical dosing on the cooling tower loop and keeps the chiller condensers free of scale. How EST works: Elgressy EST treats a side stream of the cooling water by controlled electrolysis. Calcium […]

Bridgestone Rangsit installation In 2016 we installed an Elgressy EST chemical-free cooling water treatment system at Bridgestone in Rangsit, Bangkok. The system protects the plant’s cooling towers and chillers from scale, corrosion and biofouling without anti-scalants or biocides. How EST works: Elgressy EST treats a side stream of the cooling water by controlled electrolysis. Calcium […]

UNILEVER Cavite Manila EST installation In 2018 we installed phase 1 of an Elgressy EST chemical-free cooling water treatment system at Unilever in Cavite, Manila, Philippines, with our local partner GLJM. Results after three years During a service visit in December 2021, GLJM cleaned the EST reactors. Unilever reported back to us: “Lots of scales […]

Nana Square Sukhumvit Bangkok EWT installation In 2018 we installed an Elgressy EWT system at Nana Square on Sukhumvit Road, Bangkok, for chemical-free treatment of the building’s water system. Elgressy’s electrochemical systems remove scale-forming hardness from the water and control bacteria and biofilm without adding treatment chemicals, keeping pipes, tanks and heat exchangers clean. Related […]

Upcoming projects 2019 2016 was another busy year for us. One of the most prestigious projects was delivered to Mitsubishi Motors Thailand in Laem Chabang: two Elgressy EST systems, installed in phase 1 (2015) and phase 2 (2016). Running without problems By 2019 the systems were still running flawlessly. EST keeps the cooling water in […]
