Don't Settle for Poor Heat Exchanger Performance


WSA Engineered Systems®, formerly known as Water Services of America, Inc., has been incorporated since 1971.  With thousands of systems installed globally, WSA is a world-class leader and single most authoritative source for mechanical on-line Automatic Tube Cleaning, Automatic Backwash and Water Filtration Technologies.

WSA's commitment is to deliver permanent solutions to problems of macro and micro fouling of hydraulic systems common to many industries including:

- HVAC / Commercial
- Power Generation
- Petrochemical/Refinery
- Industrial
​
Contact Salt Creek Technologies for any of your mechanical on-line heat exchanger cleaning needs.

How does the WSA Engineered System Work?​

​
Each tube is equipped with one brush and two catch baskets.  The baskets are attached to each tube end by means of special epoxy or using a patented secondary tube sheet.  Baskets are designed to allow for easy removal and replacement of the brushes when worn after years of operation.  The baskets are designed to hold the brush outside the tube and away from the fluid path to avoid flow restriction and without causing measurable additional pressure drop across the heat exchanger.
​

​The flow diverter is housed within the piping to and from the heat exchanger.  It is custom designed for various piping configurations for ease of installation and insignificant pressure drop.  This unique 4-way flow diverter allows for periodic flow reversal through the heat exchanger at preset times, without reducing or stopping the flow through the exchanger and without taking the exchanger out of service or interrupting its operation.

Picture

The flow diverter’s operation is initiated by the programmable control panel based on the cleaning frequency it is set-up for.  Once it is initiated, the diverter valve momentarily changes the flow direction through the heat exchanger, shuttling the brushes out of their parked home position into the tube until it is captured by the basket at the opposite end of the tube.  The diverter valve keeps the flow in the reversed direction for a short few minutes until it is returned back to its normal position, returning the flow inside the tube to its original normal flow direction.  Once the normal flow cycle is established, the brushes return back to their home parked position, while brushing the tube again.  The brush has a small interference fit within the tube, gently brushing away any foulant and scale that is built inside the tube between each cycle of operation.  The cycle of operation is repeated three times per day or as many times as necessary based on the process condition and the severity of fouling and scaling.  It should be noted again that the exchanger remains in full operation and without any interruption during each cleaning cycle.

Repeating the on-line cleaning cycle several times each day will prevent foulant and scale to build inside the tube inner surface and will keep the heat transfer efficiency at its highest clean and design conditions, increasing the heat exchanger’s overall performance.
