Military Cleaners

Delta Products Group was the first descaling company approved by the United States Navy for cleaning on their vessels. Of the first 30 United States submarines to be chemically cleaned, Delta Products Group was chosen for 29 of them.

NAVSEA and PSNS have written several papers detailing the uses and effectiveness of DeltaSafe D Scale. There are extensive cost comparisons showing the advantages of using DeltaSafe D Scale VS present methods of dismantling and acidizing. It is a proven fact that using DeltaSafe D Scale will improve maintenance efficiency and lower your costs. We at Delta are available to provide training and assistance to any personnel in the proper procedures and usage of our products and equipment.

Cleaning Heat Exchangers

A common piece of equipment on ships is the heat exchanger, which produces a lot of water scale. Once the scale has started, which is as soon as the heat exchanger is placed into operation, efficiency begins to decrease. Water used to cool many heat exchangers usually comes from the sea and is not monitored to maintain calcium sulfate, calcium carbonate or sodium chloride levels. This water contains many microorganisms that also attach to the tube bundle surfaces during the rapid cooling of the liquid flowing through the equipment.

Customary cleaning of the heat exchanger tube bundles is by passing air-turbine driven or hand-operated brushes and scale cutters through each tube. This technique requires complete disassembly and enough space to ramrod these devices into the tubes. Acid dipping can clean the heat exchanger however it is extremely harmful and requires many safety precautions. Delta Products Group always provides the safest and most efficient method for cleaning your equipment.

Cleaning Diesel Engines

Another traditional piece of equipment on a majority of vessels is the diesel engine, used for propulsion or as an emergency electrical generator. For these engines, dissolved impurities in the potable water used as cooling eventually form scale on hot metal surfaces reducing heat transfer and causing equipment overheating and corrosion. Lime and scale deposits in small cooling water passages cause localized overheating. This results in inadvertent wear, deterioration, sludge formation, increased fuel consumption, and increased corrosion.

Water treatment maintenance can help slow down formation of scale deposits and corrosion, but the engine will still scale up after time. A technician can then expend many man-hours cleaning critical components of scale, sometimes by one piece at a time. However, this does not firmly establish the general scaling condition of the interior of the engine passages, which may then require an acid flush. Here at Delta, we finish the job quickly and safely with our variety of cleaners and descalers.

Cleaning Plumbing Systems

The urinal drain piping is not customarily considered a scale producer. These systems may breed scale problems caused by improper installation or close proximity of a heat source. Where drain piping is installed with insufficient pitch to drain, clogging occurs. The close proximity of steam piping to a drain dries chemical deposits in the drain piping into a rock-like substance. Relocation of the steam or drain piping is the alternative to cleaning. Descaling with the cleaners that Delta Products Group offers is a simple solution.
