Semiconductor and electronics facilities cool cleanrooms, process tools and UPS rooms with tight temperature tolerance. A chiller deviation can scrap a process lot.
The Operating Reality
A fab runs process chillers, make-up air units and cleanroom HVAC through shell-and-tube condensers on cooling towers with high purity-water discipline.
Why Fouling Hurts Here
Online cleaning removes the shutdown variable and holds end-difference at ~1.2°C, supporting both energy and uptime goals without a documented manual-cleaning outage.
How Automatic Tube Cleaning (ATCS) Fits
- Sponge balls (DN100–500 compatible, 0.1 mm oversize) circulate every chiller cycle, sweeping tubes with no shutdown.
- End-difference is held near ~1.2°C instead of drifting to 3°C+, keeping compressor work in check (each 1°C of end-difference adds ~4% compressor load).
- Continuous sweeping prevents the biofilm layer (up to ~300× more insulating than clean tube) that manual schedules miss.
- Systems are sized to tube count and metallurgy — titanium, copper-nickel, stainless and carbon steel all supported.
Compliance & Standards
For new Chinese industrial and commercial cooling projects, online/automatic condenser cleaning aligns with GB/T 51357-2019 guidance that such measures be considered for energy-efficient cooling design.
