District Cooling Operators
District cooling plants move large water volumes through long closed loops and cooling tower farms. We supply closed-loop corrosion control, cooling tower conditioning, dispersant treatment and microbial control in volume, with technical support on dosing and monitoring.
Who we work with: Plant operations manager, water treatment engineer, procurement.
What you face
- Corrosion across large-volume closed chilled water loops and distribution networks.
- Scale management in cooling tower farms at high cycles of concentration.
- Heavy fouling and particulate load in tower-connected heat exchangers.
- Microbial growth and biofilm in cooling tower basins and fill.
Our approach
- NANOSAFE X molybdate-based protection for closed chilled water loops, with parameter monitoring.
- NANOSAFE X 400 DC for cooling towers and tower-connected exchangers on treated make-up water; NANOSAFE X 300 for chiller circuits.
- NANOSAFE BIOCID microbial and biofilm control programme across the tower farm.
- NANO CLEAN periodic descaling of fouled exchangers, followed by NANO CLEAN NR.

Frequently asked questions
Which treatment is used for large closed chilled water loops?
NANOSAFE X, a molybdate-based corrosion and scale inhibitor for closed loops, with parameter monitoring.
How are cooling tower farms treated at high cycles of concentration?
NANOSAFE X 400 DC on treated make-up water for scale, dispersion and corrosion control, with the NANOSAFE BIOCID microbial and biofilm control programme across the tower farm. Chiller circuits are conditioned with NANOSAFE X 300.
Can Kuvars Chem supply in volume?
Yes. Closed-loop, cooling tower and microbial control chemicals are supplied in volume, up to 1000 kg IBC, with technical support on dosing and monitoring.
