ARC360

Optimized Descaling Efficiency

As alkaline scales dissolve, the pH of the solution increases, which can reduce descaling effectiveness. However, ARC 360 allows for optimization by adding more of the product as alkalinity rises, ensuring continuous and efficient descaling. 

Corrosion Protection

ARC 360 is formulated with a complementary corrosion inhibitor to safeguard exposed metal surfaces, welds, joints, and areas subjected to heat stress in piping systems. This feature enhances asset protection, particularly in situations where frequent descaling is necessary. 

Environmentally Friendly Composition

Classified as non-harmful to the environment, ARC 360 is supplied in a concentrated form that can be easily diluted on board vessels or at the point of use. This not only reduces the amount of water and plastic transported globally but also supports sustainable practices. 

User Safety

The unique formulation of ARC 360 ensures that users are protected from acid burns, making it significantly safer compared to alternative descaling products available in the market. 

The Importance of Descaling

Descaling is a critical maintenance process across various industries, as the accumulation of scale and mineral deposits can impair equipment performance, leading to reduced efficiency, higher energy consumption, and potential equipment failure. Traditional descaling methods often involve harmful chemicals, posing risks to both the environment and operators.

ARC 360, with its active ingredient Urea Hydrochloride, provides a safe and effective alternative for descaling, gaining popularity for its eco-friendly properties and enhanced user safety.

The Advantages of Descaling

Urea Hydrochloride offers several significant advantages as a descaling agent, primarily as a safer alternative to conventional descaling chemicals. Classified as a non-hazardous material, it presents minimal risk for operators during handling and application.

Unlike traditional descalers, Urea Hydrochloride does not emit harmful fumes and is non-corrosive to equipment and machinery, which helps mitigate the risk of damage and potential equipment failures.

Another notable benefit is its environmentally friendly nature. Traditional descaling agents can pose risks to the environment by contaminating water and soil. In contrast, Urea Hydrochloride is biodegradable and does not leave behind harmful residues. Its water-soluble property also simplifies safe disposal.

Moreover, Urea Hydrochloride can be a more cost-effective choice in the long term. While the initial purchase price may be slightly higher, it ultimately saves money for companies due to its lower corrosiveness, which leads to fewer repairs and replacements. Additionally, it requires less water and energy for flushing and cleaning.

As exemplified by products like ARC360, Urea Hydrochloride is a safe, effective, and environmentally conscious alternative to traditional descaling agents. With benefits that include enhanced safety, reduced environmental impact, and long-term cost savings, Urea Hydrochloride aligns well with the growing emphasis on sustainability and safety in various industries, making it an ideal choice for descaling operations. 

Typical Marine Applications for ARC 360

Scale formation is a common operational challenge on vessels operating with seawater and mineral-rich water sources. Over time, calcium carbonate, struvite, uric scale, and other mineral deposits accumulate inside pipes, pumps, and heat transfer equipment. These deposits reduce system efficiency, restrict flow, and can lead to costly maintenance or unexpected equipment failure.

ARC 360 is specifically designed to remove these deposits safely and efficiently across a wide range of marine systems.

Typical shipboard applications include:

  • Vacuum toilet pipework and sanitary systems where mineral scale and biological deposits restrict flow and create blockages.

  • Plate heat exchangers and coolers, where scale buildup reduces heat transfer efficiency and increases energy consumption.

  • Evaporators and freshwater generators, where mineral deposits from seawater reduce freshwater production efficiency.

  • Cooling water pipe systems exposed to mineral fouling and deposits.

  • General marine process equipment where scaling and contamination from oil and grease occur simultaneously.

Because ARC 360 combines descaling and degreasing in a single formulation, engineers can clean contaminated equipment without requiring a separate degreasing stage. This simplifies maintenance procedures and reduces cleaning time during onboard servicing.

Regular descaling using ARC 360 helps restore system performance, maintain efficient heat transfer, and extend the operational life of critical marine equipment.

Improving Vessel Efficiency Through Preventive Descaling

In marine operations, even small deposits of scale can significantly impact equipment performance. A thin layer of mineral scale inside a heat exchanger or cooling pipe can reduce heat transfer efficiency and increase fuel consumption due to higher engine operating temperatures.

Preventive maintenance using professional descaling solutions is therefore an important part of modern vessel management.

ARC 360 enables ship operators to implement routine descaling programs that help maintain the efficiency of onboard systems while reducing operational risks. By removing mineral deposits before they accumulate to problematic levels, vessels can benefit from:

  • Improved heat exchanger performance

  • Reduced engine cooling system stress

  • Lower fuel consumption due to improved heat transfer

  • Reduced risk of pipe blockages in vacuum toilet systems

  • Longer service life for heat exchange equipment and piping systems

Because ARC 360 is designed as a safer alternative to aggressive mineral acids, descaling operations can often be carried out onboard during normal vessel operations without the hazards associated with traditional acid cleaning methods.

For shipowners, operators, and marine engineers, ARC 360 provides an effective and practical solution for maintaining clean, efficient marine systems while supporting safer working conditions onboard.

Frequently Asked Questions About ARC 360 Marine Descaler

What is ARC 360 used for on ships?

ARC 360 is a marine descaling solution used to remove mineral scale, grease, and organic deposits from shipboard systems. It is commonly used for cleaning vacuum toilet pipework, heat exchangers, cooling systems, evaporators, and freshwater generators where mineral scale reduces efficiency and restricts flow.


How does ARC 360 remove scale deposits?

ARC 360 works by dissolving mineral scale such as calcium carbonate and other deposits that accumulate in marine systems. The formulation penetrates scale layers and breaks them down so they can be flushed out during the cleaning process, restoring flow and improving heat transfer efficiency.


Can ARC 360 replace traditional acid descalers?

Yes. ARC 360 is designed as a safer alternative to aggressive acid descalers. It provides effective scale removal while reducing the hazards typically associated with strong acids such as hydrochloric acid. This makes handling safer for crew members during onboard cleaning operations.


Where can ARC 360 be used on marine vessels?

ARC 360 can be used in many shipboard systems where scale deposits occur, including vacuum toilet piping, marine heat exchangers, plate coolers, cooling water systems, evaporators, and freshwater generators. It is suitable for maintenance cleaning of equipment exposed to mineral fouling.


Why is descaling important for marine heat exchangers?

Scale buildup inside heat exchangers reduces heat transfer efficiency and forces cooling systems to work harder. Regular descaling removes mineral deposits, improves heat exchange performance, and helps maintain proper engine cooling and system efficiency.


How often should marine systems be descaled?

The frequency depends on operating conditions, water quality, and system design. In many vessels, descaling may be required every few months or during routine maintenance intervals to prevent scale buildup from reducing system performance.


Does ARC 360 also remove grease and oil residues?

Yes. ARC 360 has built-in degreasing capability, allowing it to remove oil residues and organic contamination in addition to mineral scale. This combination makes it useful for cleaning marine equipment where both scale and grease deposits are present.


What types of scale form in marine pipe systems?

Common types of scale found in marine pipe systems include calcium carbonate deposits from seawater minerals, struvite scale in sanitary systems, and other mineral residues formed during heating and evaporation processes.
