Condenser Tube Cleaning for Saudi Arabia’s Cooling

In a Saudi summer the cooling plant works hardest exactly when the day is least forgiving. Peak load and peak ambient arrive together, and fouling decides whether the plant holds capacity.

The Operating Reality

Plants and complexes run large centrifugal chillers on cooling towers, with make-up from seawater desalination or groundwater. Desalination product is low in hardness but corrosive; groundwater is high in dissolved solids.

Why It Matters Here

End-difference creep of about 1 C adds roughly 4% compressor work, so a fouled condenser costs the most in the hours when the plant is already at its limit. Losing capacity in the hottest afternoon can mean unmet cooling or an emergency response.

Local Conditions That Drive Fouling

• Dry-bulb temperatures of 45-50 C put tower water inside the 25-45 C growth window for much of the year, so biological fouling does not switch off.
• Desalination product water is low in hardness but aggressive to carbon steel, so corrosion control and inhibitor protection have to run together.
• Groundwater make-up with high dissolved solids raises scale risk sharply as cycles of concentration climb in dry weather.

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+, avoiding the ~4% per 1 °C compressor penalty.
• Continuous sweeping removes the biofilm layer (up to ~300× more insulating than a clean tube) rather than reacting after a deposit forms.
• Systems are sized to tube count and metallurgy — titanium, copper-nickel, stainless and carbon steel all supported.
