How Automatic Tube Cleaning Keeps Chillers Efficient All Year
Ask a plant engineer when their chiller was last at peak efficiency and the honest answer is often: “Right after the last tube cleaning.” Within weeks, biofilm and soft scale begin rebuilding on condenser tube walls, and efficiency slides — quietly, invisibly, and expensively.
The Hidden Tax of Fouling
A fouling layer even a fraction of a millimetre thick insulates the tube wall. The compressor works harder, head pressure rises, and energy consumption can climb 10–20% before the next scheduled cleaning. Over a full cooling season, that “hidden tax” usually dwarfs the cost of the cleaning itself.
Cleaning While Running
Automatic tube cleaning removes the cycle entirely. Sponge balls sweep through the tubes on a programmed schedule, wiping deposits away while they are still soft — while the chiller keeps running. Efficiency stays at design level in January and in peak summer alike.
What Plants Typically See
- Stable, low approach temperatures month after month
- Double-digit percentage savings on chiller energy
- No cleaning shutdowns and far less chemical dependence
- Longer tube life, because deposits never sit long enough to corrode
If your energy bills creep upward between cleanings, fouling is the first place to look. See how our system works.
