How To Clean Industrial Heat Exchangers
Match your cleaning method to the size and design of your heat exchanger.
For a Dramatic ‘Before’ and ‘After’
It’s easy to forget about heat exchangers. Perhaps half of all manufacturing heat exchangers are ignored until they have
problems. By the time these workhorses complain they can be so caked with deposits that you need to drill into the tubes
to clean them. Well designed maintenance routines and the proper equipment help you clean heat exchanger tubes quickly
and regularly, minimizing your risk of costly
breakdowns. Choose the right rotary tube cleaner
or an effective chemical cleaning system, and the
job’s done in no time.

Before and after images show how chemical descaling can restore a heat exchanger to peak
operating efficiency and add years to its life - right in front of your eyes.
Choose Your Cleaning System
o The RAM-5SFVS rotary tube cleaner quickly cleans large heat exchangers.
o The PSM-500 tube cleaning drill clears out straight small-diameter tubes.
Straight shooter o It’s easiest to descale U-shaped tubes with a chemical descaling system. Or use
