Generate sodium hypochlorite right at the point of use, from salt through electrolysis, for water treatment plants (WTPs), wastewater treatment plants (WWTPs), wells and water supply systems. This way, you eliminate storage of chlorine gas and concentrated chemicals. In addition, free residual chlorine remains stable throughout the network, with far greater operational safety.

Chlorinate process water, reuse water and effluent with sodium hypochlorite generated on-site. Because dosing is controlled by ORP, free residual chlorine stays stable, with no storage or handling of chlorine gas or hazardous chemicals. In addition, every system is sized by engineers according to your plant's flow rate and organic load.


Get continuous chlorine production for large-volume pools such as water parks, resorts, clubs and hotels. This way, you keep millions of liters with stable free residual chlorine and water within standards, without relying on chlorine stock or deliveries.

The generator turns ordinary salt into chlorine, automatically and continuously. While the Evo+ family is designed exclusively for residential pools, the Evoclor Pro serves shared-use pools of up to 300,000 liters. The result: balanced water without the hassle of handling chlorine.

Sanitation Line · Water utilities, industry and large-volume pools.
Get continuous hypochlorite production for WTPs, WWTPs, wells, industries and large water volumes. Since each system is sized by engineers based on flow rate (m³/h) and chlorine demand (kg/day or g/h), free residual chlorine stays within drinking water standards. As a result, there is no storage, transport or handling of concentrated chlorine gas.
Evoclor Mais and Evoclor Pro lines for pools of up to 300,000 liters.
The equipment turns ordinary salt into chlorine, automatically and continuously. It is compact and easy to install and operate. The Evoclor+ family is ideal for residential pools; the Evoclor Pro serves large residential pools and commercial pools of up to 300,000 liters — gyms, clubs and hotels.
We work side by side with engineers, designers and operators. That is why, from sizing to technical support, every installation is tailored to the volume, flow rate and standards that apply to your project, such as Brazilian standard ABNT NBR 12216 for water treatment plants.

Simple installation and maintenance, saving your team's time.
The right amount of chlorine, keeping water clean and within parameters.
Savings on chemicals and less maintenance over time.
From residential pools to large treatment plants and industries.
Your own continuous production, without depending on chlorine suppliers, freight or deliveries.
Stable residual chlorine, within the drinking water standards required in Brazil (Ministry of Health Ordinance GM/MS 888/2021).
Production by electrolysis, in the right amount, without handling concentrated chlorine.
First, salt is dissolved and fed into the system — the only input required.
Next, through electrolysis, the equipment converts the salt into hypochlorite at the exact dose.
Finally, chlorination is continuous and the system alerts you when the salt needs to be refilled.

I always used granular chlorine at the gym. If I had known salt-based treatment would be this good — water quality and fewer headaches — I would have switched sooner.
The Evo 150 Pro was the best choice for my business. We guarantee top-quality water for our customers and staff. Generating our own chlorine, without chemicals, is a very strong selling point. Highly recommended!
The Evoclor Pro transformed our routine. With salt-based treatment, we have continuous production and much more stable water. The water is always within standards. I'm very satisfied and highly recommend it!

Since our founding, H2O Geradores de Cloro has developed on-site chlorine generation technology for water treatment. We also design and manufacture reliable equipment for water utilities, industries, hotels, clubs and pool maintenance professionals.
Above all, our commitment is to deliver sustainable solutions that make water disinfection safer, more economical and more efficient.
Whenever you need it, our team of specialists will help you find the best water treatment solution for your project.
