Frequently Asked Questions

What Are Your Hours

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…


Why Should I Choose Conco TruFit™ Mechanical Tube Cleaners Over a Competitor’s?

A Conco tube cleaner with TruFit™ technology is our promise that the tube cleaner you buy is the perfect match for your tube dimensions. Exact cleaner sizing means precise blade radius for maximum cleaning action.

Conco TruFit™ tube cleaner blades do not have sharp corners or edges as some in the industry do. The Conco design prevents gouging and removal of base tube material.

Conco carbon steel cleaner blades are heat treated for strength, then tempered to create the spring action that ensures deposit removal and tube protection.

There is a TruFit™ cleaner for every type of fouling deposit, including mud, slime, algae, mussels, manganese, iron, crystalline and calcium carbonate.


How Quickly Can You Respond?

In most instances we can have a crew onsite with 24 hours. Conco arranges for crews to begin the coordination and assembly of the equipment and cleaners almost immediately.

The limiting factors are travel time and location. Air travel is based upon the airlines schedules and is limited as we try to maintain costs for our customers. In emergencies, we can take the flights that get us to the location the quickest. Driving allows us more flexibility but then our response time is affected by distance.


Do Metal Cleaners Damage Tubes

Conco’s high-quality, properly constructed metal cleaners do NOT damage tubes. The cleaner blades are tempered, and travel down the tubes without causing consequential tube wall loss.

The excerpt below is from a technical paper 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 is the Typical Size of your Crews?

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 condenser may only require 3 man crews. We can also shoot around the clock and provide 3-4 man crews per shift for 24 hour coverage.
