Shell-Side Cleaning

MCC Process

Other methods of shell side cleaning can make the outside of the tube nest look okay, but on a tight pitched bundle how do you know that the center, where the heaviest fouling accumulates, is actually clean? Only National Heat Exchange with our patented MCC Process is proven to be able to clean the whole bundle. Our high volume flow, (up to 1500 gallons per minute), of an actual cleaning agent, (not just water), that is matched to the fouling, and is heated to it's optimal cleaning temperature, coupled with the constant rotation of the bundle, is the only way to ensure the bundle is cleaned all the way to the center.

Before Shell-Side Cleaning

Now as we pull a tube from the very center of the bundle, the point where the majority of the fouling accumulates...

After Shell-Side Cleaning

...the difference is clear. The bundle is clean all the way to the center and is restored to 92% to 98% of its new efficiency! And whether the fouling is petroleum based or water minerals the results are the same.

National Heat Exchange is the only company specializing in shell-side cleaning!

MCC Environmental Health and Safety

National Heat Exchange, through our patented shell-side cleaning process, can offer your facility the absolute cleanest, safest, most environmentally friendly, and most effective heat exchanger cleaning method available anywhere.

Cleanliness

Your tube bundles are placed inside the MCC machine where there is no chance for overspray, splatter or run-off. The cleaning solution is continually processed through a closed kidney loop filtration system where all particulates are captured, then neatly disposed of.

Safety

The MCC process is a totally enclosed self-contained cleaning unit. The cleaning is accomplished thought a high volume (1,500 gal. min.), low pressure flow of a heated cleaning solution. Contrast this with traditional high pressure water blasting techniques and their inherent dangers. Even an open bubble vat offers potential dangers that our MCC overcomes.

Environmental Benefits

Traditional high pressure washing methods can generate up to 23,000 gallons of contaminated water that you have to treat. With our patented process, on certain types of coolers such as Lube Oil Coolers, Boiler Feed Pump Coolers, Seal Oil Coolers, etc., we produce ZERO liquid waste. When we have to use a water based cleaning solution we produce 93% less liquid waste that needs to be disposed of.

Efficiency

Our process can restore your heat exchangers to between 92% and 98% of their new efficiency. When the bundles are placed inside the MCC they are placed onto a series of rollers, then spray bars are setup, along the entire length of the bundle. Once setup is complete, the bundles are rotated continuously as they are bathed with 1,000 gallons a minute of cleaning solution, heated to between 160 & 180 degrees, removing even baked on deposits all the way to the center of the bundle.

All things considered, the choice is clear - When you want it clean......think NHE!
