DCW Medium
Safe water disinfection for buildings and industry
The DCW Medium is a flexible water disinfection unit designed for medium to large-sized water systems. It produces the disinfectant Neuthox® on-site using only salt, water and electricity and helps control bacteria and biofilm without hazardous chemicals.
The unit is used in applications such as cooling towers, process water, domestic water and livestock water systems, where reliable and safe operation is essential.
Automated solution. High effect. Safe operation.
Suitable for many water systems
The DCW Medium unit is suitable for a wide range of water applications that require effective disinfection, stable water quality and safe operation. Explore some of the most common applications below.
Domestic water systems
Control Legionella and biofilm in hot / cold building water systems.
Industrial cooling towers
Replace hazardous chemicals and achieve safer and more stable operations.
Industrial process water
Improve hygiene and achieve safer operations with lower costs.

Case: Documented results from Danfoss
Cleaner cooling water and higher uptime
The global engineering company Danfoss has used DCW units on cooling towers for more than 10 years, replacing strong chemicals while achieving extremely clean cooling water and eliminating production shutdowns caused by biofilm.
Documented safety
Neuthox is classified as non-hazardous according to EU regulation, which means:
- No personal protective equipment is required
- It is not flammable
- No hazard pictograms are needed
How much water can DCW Medium treat?
The table shows the approximate amount of water that each DCW Medium T15 model can treat per day in typical applications. The first column shows the unit's Neuthox production capacity in litres per hour (l/h), while treated water capacity is shown in cubic metres per day (m³/day). Actual capacity depends on the specific application and the required dosing level.
Contact us to discuss your needs| Neuthox production 500 parts per million (ppm) |
Domestic water 0.5–5 ppm dosing |
Process water 0.5–2 ppm dosing |
Livestock water 5 ppm dosing |
|---|---|---|---|
| 30 l/h | 60–600 m³/day | 150–600 m³/day | 60 m³/day |
| 40 l/h | 80–800 m³/day | 200–800 m³/day | 80 m³/day |
| 50 l/h | 100–1,000 m³/day | 250–1,000 m³/day | 100 m³/day |
| 75 l/h | 150–1,500 m³/day | 375–1,500 m³/day | 150 m³/day |
| 100 l/h | 200–2,000 m³/day | 500–2,000 m³/day | 200 m³/day |
The treated water capacity is based on 20 hours of Neuthox production per day. Neuthox is stored in a tank to ensure continuous dosing and protection 24/7.
Cooling towers
The capacity requirement for cooling towers is calculated differently because water continuously evaporates and part of the water is discharged from the system. The table below provides an indication of the recommended Neuthox production capacity for different cooling tower sizes.
| Neuthox production | Cooling tower size |
|---|---|
| 30 l/h | 900 kW |
| 50 l/h | 1,500 kW |
| 75 l/h | 2,000 kW |
Larger cooling towers may require a DCW Large unit.
