Who we are
Reliable Biofouling Control for Critical Cooling Water Systems
Why Electrochlorination?
Seawater contains naturally occurring chloride ions. Oximax electrochlorination systems utilise this abundant resource to generate sodium hypochlorite through electrolysis.
The generated sodium hypochlorite is automatically dosed into the cooling water intake where it prevents the growth of:
- Mussels
- Barnacles
- Algae
- Slime-forming bacteria
- Shellfish
- Marine microorganisms
- Biofilms
Maintaining clean cooling water systems ensures maximum heat transfer efficiency while preventing costly downtime caused by marine fouling.
Designed for Continuous Industrial Operation
Power stations and refineries rely on uninterrupted cooling water flow to maintain safe and efficient operation.
The Oximax Electrochlorination System provides:
- 24/7 continuous disinfectant generation
- Automatic chlorine residual control
- Fully automated PLC operation
- Remote monitoring and SCADA integration
- Low operating costs
- Minimal operator intervention
- Long service life
- Australian engineering and manufacturing
Each system is customised to match intake flow rates, chlorine demand and site-specific environmental requirements.
Applications
Oximax systems are ideal for:
- Coal-fired power stations
- Gas-fired power stations
- Nuclear power stations
- Combined cycle power plants
- LNG processing facilities
- Oil refineries
- Petrochemical plants
- Offshore platforms
- Desalination plants
- Marine terminals
- Steel manufacturing plants
- Fertiliser production facilities
Protecting Critical Assets
Marine growth can rapidly accumulate inside:
- Cooling water pipelines
- Condenser tubes
- Heat exchangers
- Cooling towers
- Intake screens
- Pumps
- Water boxes
- Fire water systems
Without effective treatment, biofouling causes:
- Reduced cooling efficiency
- Increased pumping energy
- Corrosion under deposits
- Blocked pipework
- Reduced plant output
- Higher maintenance costs
- Unplanned shutdowns
- Expensive cleaning programs
Oximax systems continuously prevent fouling before it becomes a problem.
Key Benefits
Improved Plant Efficiency
Clean condenser tubes and heat exchangers maximise heat transfer and improve overall thermal efficiency.
Reduced Maintenance Costs
Continuous treatment significantly reduces manual cleaning, pigging and chemical cleaning requirements.
Enhanced Asset Protection
Preventing biological deposits reduces microbiologically influenced corrosion (MIC) and extends equipment life.
Improved Operational Safety
No chlorine gas storage.
No hazardous chemical deliveries.
No bulk oxidant handling.
Environmentally Responsible
Electrochlorination produces disinfectant only as required, reducing chemical transport and minimising environmental impact while complying with discharge regulations.
Lower Lifetime Cost
Low energy consumption combined with minimal maintenance provides one of the lowest total cost of ownership available for large industrial cooling water treatment.
Oximax Electrochlorination Process
- Seawater is drawn from the intake system.
- The seawater passes through the Oximax electrolysis cells.
- Electrical current converts naturally occurring chloride ions into sodium hypochlorite.
- The generated disinfectant is collected in a storage tank.
- Metering pumps accurately dose sodium hypochlorite into the cooling water system.
- Continuous dosing prevents marine growth throughout the intake and cooling circuit.
Engineered for Harsh Marine Environments
Every Oximax system is built using industrial-grade materials designed for long-term operation in corrosive seawater environments.
Features include:
- MMO coated titanium electrodes
- Heavy-duty PVC, HDPE or FRP construction
- Industrial PLC controls
- Redundant dosing systems
- Automatic polarity reversal
- Remote diagnostics
- Low maintenance electrode design
- Modular expansion capability

common Questions
Explore Common Questions About Oximax products.
What is electrochlorination?
Why is electrochlorination preferred over chlorine gas?
Electrochlorination eliminates the need to transport and store hazardous chlorine gas, significantly improving plant safety while reducing chemical handling risks.
What types of marine growth does it control?
The system effectively controls barnacles, mussels, algae, slime, shellfish, bacteria, biofilms and other marine organisms that commonly foul seawater cooling systems.
Can the system integrate with existing plant controls?
Is electrochlorination environmentally friendly?
Yes. The disinfectant is generated on demand using seawater and electricity, reducing chemical transport and storage. Correctly designed systems provide effective biofouling control while meeting environmental discharge requirements.
What maintenance is required?
Can Oximax systems be customised?
Are your systems suitable for remote locations?
Do you provide installation and commissioning services?
Can your systems help meet regulatory compliance requirements?
Do you offer maintenance and support services?
