Condenser & Heat Exchanger Tube Cleaning
The American Efficiency Services philosophy regarding tube cleaning is this: anyone can put a cleaner in a tube and push. The individuals doing the work make the difference in quality. AES offers the most complete Condenser Cleaning available.
AES provides crews dedicated to safety, quality job performance, and completion. All personnel are full time employees of AES. Our reporting system is ready to transfer photographs and video images to our customers directly from the condenser. If you don’t know the project status, we aren’t doing our job. American Efficiency Services (AES) believes that providing the most available and accurate data during a condenser / heat exchanger tube cleaning gives our customers the ability to better plan for future cleanings and gain the competitive advantage necessary in today’s market.
AES has conducted condenser / heat exchanger tube cleanings on systems as small as 200 tubes to as large as 60,000 tubes. These systems have been on various job sites from fossil / nuclear power plants, medical waste and potash facilities. AES deploys a full suite of equipment to handle any scope of work while on site. Crews come prepared with high pressure water pumps capable of increasing plant water to 400 psi to propel the cleaner down the tube, air and water cleaning guns that use a combination of plant air and water as the mode of force pushing the cleaner down the length of tube, a rotary brush machine with various cleaning heads for smaller heat exchangers, all safety equipment, cameras, boroscope, lights and protective netting to catch the cleaners as they exit the tubes.
The selection of the correct cleaner for the deposits is the most important decision to be made prior to a condenser / heat exchanger tube cleaning. If the history is unknown AES can come equipped to the job site with various cleaners to attack the exact condition once the tube bundle is exposed. AES works closely with Goodway to offer an entire line of cleaning products from the aggressive metal scrapers for hard deposits to a plastic tube scrubber for lighter / easily removed deposits. Once AES is able to establish a history based on actual conditions, we can work closely with plant personnel to determine the most economical and effective approach for future cleanings.
AES dispatches a Safety / Documentation Manager for each condenser / heat exchanger tube cleaning scope of work. This allows the cleaning crew to focus on their personal safety responsibilities and the cleaning scope of work while the Safety / Documentation Manager focuses on overall project safety and the collection of all pertinent data.
AES’ philosophy is to “bring the condenser out of the plant and onto our customer’s desk”. If plant personnel have a clear understanding of the condenser conditions during the cleaning they can make any critical decisions immediately and prior to the system being closed. “Before” photographs of the waterbox, tube bundle and internal tube will be collected to identify the “as found” condition. Any abnormal or unique situations identified during the cleaning will also be photographed and documented. Upon completion of the cleaning, “After” photographs of the waterbox, tube bundle and internal tube will be collected to record the effectiveness of the cleaning. Individual photographs and summaries can be immediately provided to plant personnel either by flash drive or e-mail directly from the work site. At the conclusion of the cleaning all of this data will be compiled into one comprehensive report and then delivered to the customer.
A state of the art boroscope is used to collect the internal “before” and “after” photographs of the tubes. The boroscope is capable of capturing still photographs or recording video as the inspection probe is passed down the length of the tube. These photographs identify the condition of the buildup prior to the cleaning and then the effectiveness of the cleaning. If debris lodged in a tube is unable to be removed, the boroscope can be used to identify the type of debris. Identification of the debris can assist in determining whether or not the tube should be plugged regardless of the tube being evacuated of the debris. The boroscope has also been used by customers while AES crews were on-site to conduct foreign material post job inspections of other job sites within the facility.
The primary outcome of every tube cleaning must be a thorough cleaning that allows the customer to return the system back to service in a condition that allows it to achieve the highest possible heat transfer. If the waterbox, tube sheet and tubes do not get cleaned and unit performance does not return to service efficient – we did not do our job.
AES has the ability to dispatch personnel from four different locations across the country. Headquartered in Maryland, we have satellite offices located in Florida, Missouri, and Texas.
