Just add salt and water, and our devices will generate cleaning and disinfectant solution for next to nothing right in front of you

We design, develop and manufacture devices that generate cleaning and disinfectant solutions that kill microorganisms, including bacteria, viruses, spores and fungi.

These solutions are mixed oxidants that contain the active substances hypochlorous acid (HOCl), sodium hypochlorite (NaOCl, and sodium hydroxide (NaOH). These solutions are made by simply adding salt and water and applying low voltage electricity to activate the solution using a specialised electrolysis cell.

We already produce a wide range of ECA devices, but we can also speak to you about bespoke devices. Our clients include some of the world’s largest companies, and our devices are installed in establishments and facilities worldwide, on land and sea.

Who are Centrego Ltd?

Centrego Ltd has been producing ECA generators and solutions for over 15 years and is a leader in developing technology and systems. Centrego produces innovative environmentally responsible systems that reduce carbon emissions and environmental impacts for commercial and consumer markets.

Centrego is growing quickly due to demand for enhanced facilities hygiene, and clients desire to adopt environmentally responsible products that reduce their carbon footprints, reduce plastic use and wastage, reduce transport miles, and reduce dependency on synthetic chemicals. Centrego continually evolves to meet the changing needs of our clients, distributors, industry and legislation.

What is ECA solution?

ECA (Electrochemically Activated) solution is more effective at lower concentrations than ordinary bleach and kills up to 99.999% of bacteria, viruses and fungi. It does not use synthetic chemicals and is non-toxic, non-hazardous, and hypoallergenic and can be safely discharged to the drain without any environmental impact.

It has many environmental advantages, including on-site generation from natural and naturally sustainable inputs of water and salt, thus significantly reducing carbon emissions and environmental hazards associated with purchased synthetic chemicals. The solutions are safe to use for humans and the environment and leave no residues.

How do you make ECA solution?

To make ECA solutions, you add water and salt to any Centrego device, and it will activate the solution using electrolysis through a specialised cell. This will produce a mixed oxidant solution ECA solution that cleans surfaces and fabrics and kills up to 99.999% of microorganisms.

The solution concentration can be adjusted depending on the client’s needs. Once activated, it can be used on almost any surface to clean and eliminate microorganisms to enhance hygiene and protect assets, staff and customers.

What can ECA solution be used for?

ECA solution can be used for cleaning almost any surface that you can imagine. Desks, walls, floors, furniture, fabric, glass, metal, wood, plastic, etc.

Upon contact, ECA solution will kill 99.99% of bacteria and viruses. Simply spray it onto almost any material that you wish to disinfect. A microfibre cloth is the best tool to wipe the surface after the solution is applied for the most effective results. We also suggest wiping the surface until dry.

Who is using Centrego products?

We have many clients and distributors that are advocates of our range of products. Devices produced by Centrego can be found on cruise ships, farms, retail outlets, factories and many other large companies that wish to protect their customers and staff.

In the shadow of the pandemic and with more emphasis on renewable processes, centrego products are becoming more and more popular. Some of the biggest companies in the world are currently using centrego products in their facilities.

Our solution kills SARS-CoV-2 (COVID-19)

It has become more important than ever to ensure our surroundings are clean and free from infection and viruses during and after the global pandemic.

Centrego’s ECA solutions have been tested against both the surrogate SARS-CoV-2 virus and against the SARS-CoV-2 virus itself in a Government research laboratory. This is a very unusual test and is unavailable in commercial laboratories due to the extreme hazard risk. However, it evidences that ECA solutions will destroy the SARS-CoV-2 virus, which causes severe acute respiratory syndrome – Covid-19.

How do you measure the strength of ECA solution?

We measure the strength of ECA solution in Parts Per Million (ppm) of the active substance in the solution. For ECA solutions Free Available Chlorine (FAC) is the active substance.

The higher the ppm number, the higher the concentration of the solution. If the solution is of a higher concentration, then it will kill more bacteria and viruses. The activated ECA solution smells a bit like swimming pool water – this is chlorine being released. The higher the ppm then, the stronger the solution will smell like this. Testing can be carried out with FAC strips that are dipped into the solution. The strip will then change colour, and this colour is compared to a colour swatch as seen on the container to the left.

ECA solution versus other cleaning products

ECA solution is non-hazardous and non-toxic, and hypoallergenic, making it safe to apply by users. The solution is a combined cleaning agent and a powerful disinfectant, so both cleaning and disinfection tasks can be completed in a single application.

ECA solutions eliminate microorganisms virtually on contact – this can be seen in this video. Click here to watch. This means that no dwell time is required for most tasks, leading to more effective and efficient cleaning regimes by cleaning staff.

Manufactured synthetic chemicals carry high carbon emission levels due to manufacturing process, transport, plastic containerisation, and package and waste disposal. Using ECA systems and making cleaning and disinfectant solutions at the user’s site dramatically reduces the carbon footprint and environmental impact for the user and their company.

Hypochlorous acid (HOCl) is the key active substance of ECA solutions. HOCl is also produced by macroorganisms, including humans, when bacteria, viruses, fungi or spores take hold or skin is damaged. HOCl is naturally produced and mobilised by the body to fight infections. In many countries, HOCl is used as a wound-care treatment or in dental work to provide natural healing for infection control.

Because the human body recognises HOCl it means that ECA solution is not harmful or toxic. On the other hand, many synthetic cleaning and disinfection chemicals can be detrimental to skin and the respiratory system – as witnessed by the danger signs on containers. ECA solution application requires no PPE for users and requires no hazardous warning vectors on the solutions.

How does using ECA solution protect the environment?

The manufacturing of the ECA device requires electronics, plastics and energy–carbon emissions. Centrego takes care to ensure that locally sourced components are used wherever possible, and all are traceable to comply with Centrego’s low carbon emission policy. However, once installed on-site, the carbon emissions from generating 1l of solution is minimal. In addition, there are no plastic containers delivered and to be disposed of as with purchased chemicals, no wastage and no pollution hazards.

We all need to make changes to help the environment. ECA solutions are great for customers, great for the staff, great for the public and incredible for the planet.
