Middle East Heat Exchanger: Scale Cleared, Chemicals Cut

Home 9 Case Studies and Results 9 Middle East Heat Exchanger: Scale Cleared, Chemicals Cut

Key results

75% drop in pressure across exchanger

2.5× heat transfer increase

8°C rise in cooling outlet temp

The Challenges
Severe scale deposits blocking heat exchanger tubes
High pressure drop across the shell-and-tube unit
Heat transfer efficiency falling as scale built up
Ongoing chemical treatment to manage scale and corrosion
Environmental pressure to reduce chemical use on site

The Solution

One HydroFLOW® C120 unit was fitted to the heat exchanger inlet pipe in June 1994, treating untreated mains water during normal operation, with no shutdown required. The signal disrupts the conditions that bond scale to surfaces, so existing limescale loosens and washes through while new growth doesn’t form.
