Malls & Commercial Complexes
A mall chiller plant has no spare capacity in summer. We clean and protect mall-scale chillers, cooling towers and piping, and flush new installations before handover.
Who we work with: Facilities director, chief engineer, FM contractor, fit-out and retrofit project manager.
What you face
- Scale and fouling in large chiller systems reduce condenser heat transfer and chiller efficiency.
- Cooling tower farms under high load accumulate scale, biofilm and algae.
- New mall builds and HVAC retrofits need pre-commissioning flushing before the system is handed over.
- Micro-leaks in HVAC circulation, terrace waterproofing failures and subfloor seepage during and after construction.
Our approach
- Chiller and AHU two-stage cleaning with CLIMA CLEAR and NANO CLEAN, planned in phases across the plant.
- Cooling tower treatment: NANOSAFE X 400 DC on treated make-up water with the NANOSAFE BIOCID microbial and biofilm control programme; NANOSAFE X 300 in chiller circuits.
- NANO CLEAN and NANO CLEAN NR pre-commissioning flushing for new installations and retrofits.
- WTR RESIST for terrace, subfloor and piping leak sealing.

Frequently asked questions
How is a mall chiller plant cleaned without losing summer capacity?
The two-stage cleaning (CLIMA CLEAR and NANO CLEAN, followed by NANO CLEAN NR) is planned in phases across the plant.
Which treatment does a mall cooling tower farm need?
NANOSAFE X 400 DC on treated make-up water for scale, dispersion and corrosion control, with the NANOSAFE BIOCID microbial and biofilm control programme. The chiller circuits are conditioned with NANOSAFE X 300.
Do you flush new mall installations and HVAC retrofits before handover?
Yes. New builds and retrofits are flushed in two steps with NANO CLEAN and NANO CLEAN NR before the system is handed over.
