RXSOL SEA CHEST ANTIFOULANT is a specialized liquid treatment developed to help control marine growth in sea chests, seawater cooling lines, strainers, filter boxes and associated heat exchange systems. It is designed for use in marine seawater circuits where fouling by algae, shellfish, slime and other marine organisms can reduce flow, impair heat transfer efficiency and increase maintenance requirements.
The product forms a protective conditioning effect within the system, helping reduce the attachment and development of marine growth while supporting cleaner internal surfaces and improved operational reliability. Regular use helps maintain circulation efficiency, reduce blockage risk and minimize unplanned downtime.
Ensure all systems are completely free of marine growth prior to applying AQUASPERSE RXSOL. Where required, pre-clean using DESCALING LIQUID EXTRA or RXSOL Safe Acid DESCALEX POWDER. Marine organisms require a surface to anchor; if existing growth is not removed beforehand, it will continue to provide a base for further attachment even after AQUASPERSE RXSOL Sea Chest Antifoulant dosing.
SEAWATER COOLING SYSTEMS
Inject AQUASPERSE into the sea chests using dosing equipment once every two days for a duration of one hour, adjusted according to the seawater flow rate of the system. In harbour conditions or areas with high shellfish activity, increase dosing frequency to once daily.
A concentration of 3 ppm AQUASPERSE RXSOL is adequate for fouling prevention. This corresponds to a dosage of 0.3 litres per 100 tons per hour of seawater flow.
DEEP SEA VESSELS
Dose RXSOL AQUASPERSE into the suction box or strainers at a rate of 0.3 litres per 100 tons of flow, applied over one hour every 48 hours.
COASTAL VESSELS
Meter AQUASPERSE into the suction boxes or strainers at 0.3 litres per 100 tons of seawater flow, distributed over a 24-hour period.
Example:
For a circulating pump capacity of 250 TPH, the required dosage is:
0.3 × 2.5 = 0.75 litres of AQUASPERSE for one hour.
Features and benefits of using RXSOL Sea Chest Antifoulant
For best performance, the system should be as clean as possible before starting routine antifoulant treatment. Heavy deposits, scale or established marine growth should be removed through suitable cleaning/descaling procedures before application.
General preventive dosing:
Dose into sea chest, suction side, strainer box or designated injection point using suitable chemical dosing equipment.
Typical treatment guidance:
A preventive dose may be applied based on seawater flow rate and vessel operating conditions. Treatment frequency can be increased in harbour operations, warm waters, or areas prone to heavy marine growth.
Indicative example format:
For systems with known seawater circulation rates, dosing can be calculated proportionally per 100 tons/hour of seawater flow.
Important:
Final dosage, frequency and compatibility should be validated by RXSOL technical team before release on TDS/PDS and before onboard use.
Ecosperse Plus
RXSOL SEA CHEST ANTIFOULANT is a high-performance liquid treatment for controlling marine fouling in sea chests and seawater cooling systems. It helps prevent the build-up of algae, shellfish, slime and other marine organisms that reduce flow efficiency and interfere with heat transfer. Regular dosing supports cleaner seawater lines, improved cooling efficiency and reduced maintenance downtime. Suitable for sea chests, strainers, filter boxes, seawater lines and heat exchangers, this easy-to-use preventive treatment is ideal for both deep sea and coastal vessel operations.
