RXSOL System Flushing & Cleaning Chemical is intended to work through a combination of cleaning mechanisms:
Degreasing: Surfactants and compatible cleaning agents help emulsify cutting oils, grease and oily fabrication residues.
Wetting and Penetration: Wetting agents improve contact between the cleaning solution and deposits on internal metal surfaces.
Dispersion: Dispersing agents help suspend fine rust particles, sludge and other removable solids in the circulating water.
Chelation: Where included in the formulation, chelating agents can assist in mobilizing certain metal-containing deposits.
Flushing Action: Circulation and filtration physically remove loosened particles, welding debris and construction contamination.
Limitation: A mildly alkaline cleaner will not reliably dissolve heavy, adherent mill scale or iron oxide. These may require a separate inhibited acid or specialized chelant-based cleaning procedure.
The following ranges are proposed for initial trials with a validated, mildly alkaline flushing formulation.
|

2.0–3.0% |
6–12 hours |
|

Determined by deposit analysis |
Concentrations are expressed as percentage by volume of the final cleaning solution.
These values are provisional development recommendations, not verified field instructions for an existing RXSOL product.
01
System inspection and preparation
Confirm system volume, piping materials, pump capacity, valve arrangement and drainage facilities. Isolate sensitive components and provide suitable temporary bypasses where required.
02
Initial water flushing
Fill with suitable clean water and carry out dynamic flushing to remove loose construction debris. Clean strainers and filters regularly.
03
Chemical preparation
Prepare the selected cleaning concentration using water of suitable quality. Introduce the cleaner through an approved dosing or circulation point.
04
Chemical circulation
Circulate the cleaning solution through all intended sections of the system. Maintain sufficient flow to reach remote branches without exceeding equipment limits. Monitor pH, temperature, appearance and filtration condition.
05
Cleaning verification
Inspect strainers and representative samples. Where practical, measure suspended solids, iron concentration and oil contamination to evaluate cleaning progress.
06
Drainage and final flushing
Collect spent solution for appropriate treatment or disposal. Flush thoroughly with clean water until residual cleaner and suspended contamination meet the agreed acceptance criteria.
07
Post-cleaning passivation
Immediately apply a compatible corrosion inhibitor or passivation treatment to exposed metal surfaces, then establish the permanent water treatment programme.
After cleaning, exposed carbon steel surfaces can be particularly susceptible to flash rusting. Passivation should therefore follow promptly after the final rinse.
Confirm the system is free of excessive cleaning chemical and suspended solids.
Select a corrosion inhibitor compatible with the system metallurgy and operating conditions.
Prepare the passivation solution using water of suitable quality.
Circulate the solution to ensure contact with all wetted surfaces.
Monitor pH and inhibitor residual.
Establish the permanent closed-loop corrosion inhibitor concentration.
Maintain circulation or an approved lay-up treatment until commissioning.

PROEDURE OF USE:-
1st Method:-
Mix 1 part of RXSOL-10-1005-025 with 2 -10 parts of water / GAS-OIL , For heavy oil,greasy surface use directly)Spray directly on the entire surface to be cleaned. This can be achieved by Hand spray / mechanical spray pump. Immediately after 2 -5 minute of spray the RXSOL-10-1005-025 starts its function. The Dirt, oil grease etc will loosen. 5 to 6 minutes after spraying start rinsing the system with water (High pressure recommended). Dirt and mud starts vanishing with cleaning media and water.
2nd Method:-
Application in immersion process with or without ultrasonic support, manual wipping.
3rd Method:-
RXSOL-10-1005-025 is also used in conjunction with alkaline degreasing bath at 3-5% (v/v) concentration for better and quick degreasing action. Eithers the bath is heated to be 70c or the solution can be stirred or air agitated.
Product Code: RXSOL-25-1048-020
Procedure-of-use: The most effective descaling is accomplished by circulation.In the case of small components,the soak method in an immersion bath can be used. If the equipment to be cleaned is contaminated by oil, grease or sludge, then pre-cleaning with DEGREASER ( RXSOL OB 1005 ) is necessary. Depending on the extent of scaling, use a solution of 2.5-10% RXSOL-54-1008-025 . The solution will have a red colour which changes to orange when 85% of the acid has been neutralized , & to colourless when the solution is totally neutralized. Whenever possible, the solution should be heated to 60°C.Neutralised solutions can be re-activated by adding more RXSOL-54-1008-025 until the red colour reappears.
Fields: Descaling of Boilers, Descaling of Diesel Engine Cooling Systems, Condenser, Pipeline collection system, Evaporators, Calorifiers, Heat Exchangers,The strength of the acid can be enhanced by adding 1part sodium chloride (common salt) to 20 parts of Descalex.If salt is not available, an acceptable alternative is to dissolve RXSOL-54-1008-025 in sea water. After use of RXSOL-54-1008-025 a 0.5% solution of Alkalinity Control in fresh water should be used for neutralization.
RXSOL-54-1048-020 should not be used on Aluminium, Zinc, Tin, or any Galvanized Surfaces for which a special grade cleaner should be used. Chemical Cleaning Module RX cleansers has developed a 280 litres capacity cleaning module, primarily designed for use with chemical acid solvents for descaling boilers, calorifiers, heat exchangers & other types of equipment where rust & scale form RXSOL-11-1008--DC Boilers, See RX cleansers Practical Application Manual
The engine room is the heart of any vessel, responsible for the propulsion and essential power systems that keep the ship running smoothly. Proper engine room maintenance is critical to ensuring safety, efficiency, and regulatory compliance. At RXMARINE International, we specialize in providing high-quality marine chemicals that enhance maintenance procedures, keeping vessels in top condition.
Prevents Downtime & Costly Repairs: Regular inspections help detect early signs of wear and tear, reducing expensive breakdowns.
Enhances Fuel Efficiency: A well-maintained engine operates efficiently, cutting down fuel consumption and operational costs.
Ensures Crew Safety: Proper maintenance minimizes the risk of hazardous incidents such as fires, leaks, or mechanical failures.
Regulatory Compliance: Compliance with international maritime regulations (IMO, SOLAS) is essential to avoid fines and ensure smooth sailing.
The accumulation of oil, grease, and dirt can lead to overheating and reduced efficiency. Using RXMARINE’s Engine Room Cleaners & Degreasers, you can effectively remove sludge, carbon deposits, and oil residues.
Regular oil changes using high-quality marine lubricants help prevent friction and wear.
Monitoring oil viscosity and contamination is crucial to detect potential engine issues early.
Scale and corrosion in heat exchangers and cooling lines reduce efficiency. Descaling chemicals like RXMARINE’s RXSCALE help prevent blockages and maintain optimal cooling.
Ensure coolant levels are checked regularly to prevent overheating.
Fuel contamination with water, sludge, and microbial growth can affect engine performance. Using fuel additives and biocides prevents clogging and improves combustion efficiency.
Regularly clean fuel injectors and filters to maintain smooth operation.
The bilge area accumulates oil and sludge, which can pose environmental and safety hazards.
RXMARINE’s Oil Spill Dispersants & Bilge Cleaners effectively break down oil and prevent pollution.
Saltwater exposure accelerates corrosion in pipes, tanks, and metal surfaces.
Apply corrosion inhibitors and protective coatings to extend the life of engine room components.

STRUCTURE :
HEAD - Molecule have a long chain non polar Hydrocarbon, whose structure can be Studied as follows:-
Head : It is water soluble & ‘-‘Vely charged.
Tail : It is oil soluble.
CLEANSING ACTION
When solution water is poured over the DIRTY surface the hydrocarbon Tail of the each molecules peg in to it, while the (–ve) HEAD is held in water. The dirt or grease layer is then disloged from the skin by rubbing or from garment by tumbling and stirring. Each grease globule thus separated in PIN CUSHIONED by hydrocarbon TAILS with (-ve) HEADS out wards in water. The (-ve) HEAD globules keep apart by mutual repulsions & are said to have emulsified.The emulsified grease globules bearing dirt can be readly washed with water.
