How to Clean Heat Exchangers

The difficulties of cleaning a fouled heat exchanger present a significant challenge to the maintenance and operation of chemical, petroleum and food processes. With internal contamination heat exchangers cannot usually be cleaned using normal methods (blasting, brushing, etc). But the combination of chemical, heat, agitation and ultrasonic power has proved an excellent way in removing industrial scale, calcium deposits, rust and carbonised oils from the tubes and other cavities within heat exchangers. Submersion in an ultrasonic cleaner with the appropriate chemical restores heat exchangers to optimal performance with no damage.
