A safe and simple system to control Legionella in hot water systems – without adding any chemicals
BacTerminator® Safe is an on-site system which, using drinking water, electricity and NaCl (table salt) produces an extremely effective disinfectant, also known as ECA (Electrochemically Activated Water).
ECA water is known as a highly effective disinfectant against Legionella and biofilm. The system’s operating costs are very low, and minimal monitoring is required for optimal functioning.
The advanced electrolytic cell was developed and made in Denmark by Adept Water Technologies. It is one of the most efficient electrolytic cells on the market, meaning that electricity and NaCl consumption is very low. Production of a concentration 0.5 ppm ECA water in 1,000 litres of water consumes a mere 20 W*h and 1.5 g NaCl. This means that even big units such as schools, nursing homes, hospitals and housing associations can be secured for a few cent’s a day.
- Hot water systems in schools, hospitals, office buildings, residences, public buildings
- Drinking water systems
- Process water
- Cooling water
- Water to be stored
Simple, robust, compact and smart
The BacTerminator® Safe is designed to require minimal service. The system is typically inspected once a week to check that the salt level and the pre-filter are in order. Topping up the NaCl (salt) and replacing the pre-filter take less than 10 minutes without having to shut down the system.
The system has an inbuilt control and monitoring system. This means that you will be alerted if the pre-filter needs replacement, or additional NaCl (salt) is required. The system also has a log function, so you can check the operating parameters’ history. BacTerminator® Safe is simple to install and your own plumber can do it if he is trained by Adept Water Technologies. He can also perform your annual service and provide the consumables you need during the year.
BacTerminator® Safe is supplied complete for installation, including a complete BacTerminator® Safesystem containing controls, BacTerminator® technology, the required pre-filter, salt tank, dosing pump and inlet for pulse from the water meter. The system can be supplied with a sensor for online monitoring of your water system.

- Disinfects with extremely high efficiency
- Low operating costs
- Requires no storage and handling of chemicals
- No increased risk of corrosion thanks to an extremely low chlorine content
- Needs only minimal ongoing maintenance
- Easy to install
- Has inbuilt monitoring for high security
Facts: ECA water
When water containing chloride (Cl) runs through the electrolytic cell, free chlorine in the form of Cl2 is formed in the water.
This reacts very quickly with the water and forms an equilibrium of hypochlorous acid (HClO) and hypochlorite (OCl-). These two substances are also called free chlorine. Free chlorine is considered to be one of the most effective disinfectants and it is by far the most commonly used disinfectant globally for drinking water.
The hot water system will typically be given a dose of around 0.3 ppm, which corresponds to the levels used in Sweden and Germany and elsewhere to treat drinking water.
Facts: the latest research has shown that ECA water is better at disinfecting than both hypochlorite (OCl-) and chlorine dioxide (ClO2)

Example: One school with 1,000 pupils uses an average of 4,000 litres of hot water a day. Legionella control with BacTerminator® SAFE and 0.3 ppm ECA water will use 100 W/h and 10 g NaCl – a cost of less than € 0,1 a day.
