RXSOL Ship Engine Maintenance Chemicals: Complete Solutions for Marine Engine & Engine Room Maintenance

Marine engines operate continuously under demanding conditions where heat, scale, corrosion, oil, grease, carbon deposits and contaminated cooling systems can reduce equipment efficiency and increase maintenance costs. Regular chemical cleaning and water treatment are therefore essential for maintaining reliable ship-engine performance.

RXSOL offers a range of specialized marine maintenance chemicals designed to support engine-room cleaning, cooling-water treatment, descaling, air-cooler cleaning and general degreasing operations.

Four useful RXSOL products for ship and engine-room maintenance are:

• ROCCOR NB LIQUID – Cooling Water Corrosion & Scale Inhibitor

• RXSOL DESCALING LIQUID – Engine & Heat-Transfer Equipment Descaler

• AQUATUFF – High-Foam Alkaline Cleaner & Degreaser

• ACC PLUS – Diesel Engine Air Cooler & Turbocharger Cleaner

1. ROCCOR NB LIQUID – Engine Cooling Water Treatment

ROCCOR NB Liquid is a concentrated cooling-water treatment designed for closed cooling-water systems used in internal-combustion engines, compressors, DG sets and other equipment.

Its formulation combines corrosion inhibitors, antiscalants, dispersants and a non-carbonate buffer system to help control corrosion and scale formation in cooling-water circuits.

ROCCOR NB is suitable for protecting ferrous and non-ferrous metals, including components containing cast iron, mild steel and copper. It is particularly useful where reliable protection of engine jacket-water systems and clean heat-transfer surfaces is required.

Key Benefits of ROCCOR NB Liquid

• Helps control corrosion in closed cooling-water systems

• Helps prevent scale formation and metal oxide deposits

• Protects ferrous and non-ferrous metals

• Supports clean heat-transfer surfaces

• Suitable for diesel engines and DG sets

• Useful for compressors and other closed cooling systems

• Helps reduce cooling-system maintenance requirements

• Treatment can be monitored through appropriate water-quality testing

Regular monitoring of parameters such as nitrite, chloride and pH is important to maintain the treatment at the desired operating level.

2. RXSOL DESCALING LIQUID – Diesel Engine & Cooling-System Descaler

Scale deposits inside cooling systems, heat exchangers, boilers, condensers and other heat-transfer equipment can restrict water circulation and reduce heat-transfer efficiency.

RXSOL Descaling Liquid, RXSOL-11-1008-025, is formulated to dissolve mineral scale and rust deposits from water-cooled and water-heated equipment. RXSOL specifically lists diesel engine cooling systems, boilers, calorifiers, heat exchangers, condensers and evaporators among its applications.

Typical Marine Applications

RXSOL Descaling Liquid can be used for cleaning:

• Diesel engine cooling systems

• Jacket-water cooling circuits

• Heat exchangers

• Condensers

• Evaporators

• Boilers

• Calorifiers

• Other water-cooled equipment

The product is suitable for circulation or soaking applications, depending on the equipment and degree of scale contamination. Cleaning concentration and procedure should be selected according to the severity of deposits and the equipment manufacturer's requirements.

Benefits of Regular Descaling

Effective scale removal can help:

• Restore heat-transfer efficiency

• Reduce overheating problems caused by deposits

• Improve water circulation

• Reduce unnecessary equipment downtime

• Extend useful equipment life

• Support preventive maintenance programs

Important: RXSOL product information specifies restrictions for certain metals, including aluminium, zinc, tin and galvanized surfaces for the applicable descaling formulation. Always verify material compatibility and follow the current product technical and safety documentation before use.

3. AQUATUFF – High-Foam Alkaline Cleaner & Degreaser

RXSOL AQUATUFF is a concentrated water-based alkaline cleaner with high-foaming characteristics. It is primarily positioned for ship-hold cleaning and general degreasing, making it useful as part of the broader vessel and engine-room cleaning program.

AQUATUFF contains wetting and penetrating components along with alkaline cleaning materials and surfactants that produce an effective cleaning solution after dilution.

AQUATUFF Applications

Depending on the cleaning requirement, AQUATUFF can support removal of:

• Oil and grease residues

• Mineral-oil contamination

• Coal and soot-related residues

• General heavy dirt

• Greasy deposits from vessel surfaces

• Contamination requiring high-foam alkaline cleaning

It can be applied using suitable spray, brushing or high-/low-pressure cleaning equipment, according to the cleaning procedure.

AQUATUFF in Engine-Room Maintenance

Although AQUATUFF is not positioned primarily as a dedicated engine internal cleaner, its general degreasing capability makes it useful for cleaning suitable external engine-room surfaces, machinery areas and heavily contaminated maintenance areas where an alkaline high-foam cleaner is appropriate.

4. ACC PLUS – Diesel Engine Air Cooler & Turbocharger Cleaner

RXSOL ACC PLUS is a specialized marine cleaning chemical for diesel engine air coolers, scavenging-air systems and turbocharger compressors.

RXSOL describes ACC PLUS as a concentrated organic solvent/emulsion-based cleaner capable of dissolving oily and carbonaceous deposits. Proper cleaning of air-cooler surfaces can help maintain efficient airflow and heat transfer.

ACC PLUS Applications

ACC PLUS is designed for:

• Diesel engine air coolers

• Turbocharger compressors

• Scavenging air systems

• Engine-room maintenance areas

• Machinery parts contaminated with oil and grease

• Removal of light carbon deposits from suitable machinery parts

RXSOL states that the product can be diluted with fresh water depending on contamination, with its product information giving a 1–10% dilution range for air-cooler cleaning.

Key Advantages

• Helps dissolve oily deposits

• Effective against carbonaceous contamination

• Supports air-cooler cleaning

• Helps maintain air-cooler efficiency

• Water-soluble after dilution

• Can also be used for suitable general degreasing applications

• Available in multiple pack sizes

RXSOL lists ACC PLUS in 20, 25, 50 and 210 Litre pack sizes.

RXSOL Complete Ship Engine Maintenance Chemical Program

These four products address different maintenance requirements:

Why Choose RXSOL for Ship Engine Maintenance?

A well-planned engine maintenance program requires more than simply cleaning visible contamination. Cooling-water chemistry, heat-transfer surfaces, air coolers, turbocharger systems and external machinery surfaces all require appropriate maintenance procedures.

RXSOL provides specialized marine chemicals for different stages of this maintenance cycle—from cooling-water corrosion protection and scale removal to air-cooler cleaning and general degreasing.

Using the correct chemical for the specific contamination can help ship operators and maintenance teams improve cleaning efficiency, reduce unnecessary downtime and support reliable equipment operation.
