Chemical Cleaning and Flushing of Chilled Water System
Proper commissioning of chilled water pipework is critical to ensure long-term efficiency, reliability, and protection of your air conditioning system. In Hong Kong, the Architectural Services Department (ArchSD) Testing & Commissioning Procedure (TCP-AC-2022) specifies that new or modified chilled water systems must undergo chemical cleaning and flushing before operation.
Why It’s Required
Removes debris and contaminants such as welding slag, scale, and installation residues from new pipes.
Eliminates stagnant water deposits that build up during renovations or downtime.
Prevents corrosion and bacterial growth, safeguarding pumps, chillers, and terminal units.
Meets statutory and industry standards for handover and long-term system health.
From Contaminated to Clean
During construction or renovation, chilled water systems can accumulate welding slag, mill scale, rust, and stagnant water deposits. Left untreated, these contaminants circulate through pumps, chillers, and coils — causing corrosion, fouling, and reduced efficiency.
Our chemical cleaning and flushing process transforms the system water from dirty and contaminated to clear, treated, and stable. The difference is visible — and critical for long-term system performance.
Our Process
High-velocity flushing of pipework in controlled sections to clear loose debris.
Chemical dispersant cleaning is carried out for the required duration — typically up to 48 hours for new installations, and shorter periods for existing systems depending on water quality and system condition. This will dissolve and remove fine deposits, in accordance with ArchSD requirements.
System draining and water sampling until iron, copper and chemical residues are below 1 ppm.
Corrosion inhibitor dosing to protect the system during operation.
Final flushing and recommissioning checks, ensuring the chilled water system is clean, safe, and ready for service.

Our Chemicals
TURBO 1960 - WATER SYSTEM CLEANER/CONDITIONER
TURBO 1960 is a high-performance chemical mixture designed for the pre-operational cleaning and conditioning of newly constructed piping.
TURBO 1200 - CLOSED SYSTEM INHIBITOR
TURBO 1200 is a highly concentrated liquid blend of alkaline buffers, nitrite, and an azole metal corrosion inhibitor. Due to the multi-component blend of corrosion inhibitors, TURBO 1200 provides superior protection to steel, copper and a wide range other metal.
TURBO A18 - ANTI-FOAMING AGENT FOR WATER TREATMENT
TURBO A18 is highly effective formula that reduces foaming in water systems. This product is applicable in many water systems including open recirculating cooling systems as well as wastewater systems.
