Frequently Asked Questions
Why should I choose Conco TruFit® mechanical tube cleaners?
TruFit® tube cleaners are manufactured in the US based on almost 100 years of tube cleaning experience. A Conco tube cleaner with TruFit® technology guarantees that the tube cleaner you buy is the perfect match for the tube dimensions provided. Exact cleaner sizing means precise blade radius for maximum cleaning action.
Do metal cleaners damage tubes?
Conco’s high-quality, properly constructed metal cleaners do NOT damage tubes. The cleaner travels down the tubes without causing consequential tube wall loss.
The excerpt below is from a technical paper, published by ASME, titled “The Practical Application & Innovation of Cleaning Technology for Condensers.”
“It was found that after 100 passes of (Conco) cleaners, wall thickness reduction was only between 0.0005" and 0.0009" (12.5and 23 μm). At this rate, extrapolating the worst-case removal from this series of tests for a 0.049" wall thickness, it would take about 2,700 passes of a cleaner per tube, or roughly 1,000 years of annual condenser cleanings to result in a critical reduction in tube wall loss.”

What propels the cleaner down the tubes?
We use 100% water for our propulsion source. This provides a consistent force that drives the cleaners through the most difficult fouling and also removes the loose debris in front of the cleaner preventing build up and stuck cleaners.
What types of deposits can be cleaned?
At Conco, we know that tall fouling is not created equal. Because tube deposits can be soft, hard, or somewhere in between, we have engineered many different configurations of TruFit® tube cleaners to tackle any type of deposit. Whether you have a problem with mud, algae, manganese, iron, corrosion product, crystalline, calcium carbonate, polymers, hydrocarbons, or any other deposit, Conco has your TruFit™ solution.
What is your response time?
Conco can be reached 24/7. Our offices operate on a typical 8am to 5pm business schedule; however, our answering service is on duty around the clock and is ready to relay emergency situations to Conco personnel. Help is available day or night.
In most instances, we can have a crew onsite within 24 hours. Conco arranges for crews to begin the coordination and assembly of the equipment and cleaners almost immediately.
What is the typical size of a Conco crew?
This greatly depends upon the size of the unit and the timeframe the plant has for the outage. The most common crew size is 4 men per shift. This takes into account the need for the hole watch. However, smaller condensers may only require 3 man crews.
Are your crews made up of Conco employed technicians or do you use day laborers?
All Conco crews are trained and employed by Conco. This allows us to make sure the technicians sent to the customer's site are trained in how to perform the work correctly, efficiently, and safely.
