MEP Contractors & Construction
New installations carry welding residues, mill scale, oil films and construction debris. We flush the system in two steps, NANO CLEAN then NANO CLEAN NR, seal micro-leaks found after pressure testing and put the loop on protective dosing, with a flushing record for the handover file.
Who we work with: MEP project manager, commissioning engineer, main contractor, consultant.
What you face
- Welding residues, mill scale and metal fines in newly installed piping reach pumps, valves and exchangers in the first season.
- Construction debris and oil films from fabrication and assembly.
- Standby-period corrosion between installation and commissioning.
- The consultant asks for flushing to specification and a record for handover, and the construction programme gives you days, not weeks.
Our approach
- Step 1: NANO CLEAN chemical flush circulated through the new system to remove construction contaminants.
- Step 2: NANO CLEAN NR neutralisation to handover-grade pH and compliant discharge.
- WTR RESIST sealing of micro-leaks found after pressure testing, without opening finished surfaces.
- NANOSAFE X protective dosing before handover so the loop is delivered protected; flushing record issued.

Frequently asked questions
What is two-step chemical flushing?
Step 1: NANO CLEAN is circulated through the new system to remove welding residues, mill scale, oil films and construction debris. Step 2: NANO CLEAN NR neutralises the system to handover-grade pH and compliant discharge.
Do you provide a flushing record for the handover file?
Yes. A flushing record is issued for every flushed system.
What if micro-leaks are found after pressure testing?
WTR RESIST seals them without opening finished surfaces.
How is the loop protected between flushing and handover?
NANOSAFE X protective dosing is added before handover, so the loop is delivered protected.
