Made in Germany


The compact, cost-efficient unit design integrates control electronics with simplified-to-the-essential functionality and operation, and a pre-installed sacrificial electrode which is available in different sizes depending on project requirement and budget.

In combination with its strong amperage performance and its treatment cell with stepped-up pressure rating and certified drinking water-safe coating, the unit is highly versatile and suitable for treatment of potable, grey and process water as well as of irrigation water applied to greens and crops, notably winegrowing. Further applications include treatment of water used in animal production, and in bathing pools.

NEC-4000 is designed solely for electro-physical treatment of water and constitutes the most powerful of the single-electrode NECON systems.

Multiple units can be operated simultaneously in one installation and optionally ordered rack-mounted and piped ("Ion Towers").
