Tube Cleaning By Brush Method
The best way to eliminate energy-zapping sludge and scale.
Drop the heads on a chiller in the winter and you’ll find slime, sludge and scale – maybe tubes that are packed solid with deposits. When you have thousands of tubes to service, your cleaning method matters. For most chillers, that means using a rotary tube cleaner with water flush to power through clogged tubes fast. The spinning shaft propels a scrubbing attachment the length of the tube, loosening deposits, while the high pressure water stream flushes them out. If you’re dealing with enhanced (rifled) tubes, you’ll need a machine and attachments that are made specifically for the grooved interiors.
ScaleBreak
Double your cleaning punch with chemical descaling. Scale Break softens thick scale, speeding up mechanical cleaning. Periodic chemical descaling controls buildup between rotary cleaning.
Why work blind?
The naked eye sees only the first few inches of a fouled tube. Video scopes show clearly what you’re fighting and when you’ve won.

Clean thoroughly, then simply mix the two-part epoxy and apply with a roller or brush for superior protection.
Cleaning Internally Enhanced Tubes
Enhanced tubes are more efficient – but only when they’re clean. Rifling in the tube increases surface area, which speeds heat exchange. However, grooves are prone to fouling, accumulating slime, sludge and scale. The RAM-6 features a variable speed motor that lets you match the shaft speed to the natural feed rate of the tube’s spiral. Your brush bristles slip right into the grooves, scrubbing them clean. The machine’s reversible motor, with bi-directional foot switch, provides forward rotation for entering the tubes and reverse rotation for exiting, so you’re cleaning on the way in and on the way out. Choose the “Patriot” Dual Diameter Nylon Brush for optimal cleaning. The large diameter end reaches into the grooves; the smaller end scours the lands.
