Recurring water hygiene issues
Biofilm and slime can form inside water supply equipment, cleaning systems, pipes, and tanks.
For Equipment Manufacturers & System Developers
Electrolytic ozone water generation, built into your products and systems
Astozein develops compact electrolytic ozone water generator modules for integration into products, equipment, and water systems — for manufacturers and engineering teams working on biofilm control, slime, odor, and water hygiene challenges.
Tap water based
Designed to generate ozone water where the system uses water.
Compact modules
MARUS for compact embedded equipment. RAIDEN for fixed systems.
System integration
For OEM products, water infrastructure, and hygiene-focused applications.
Why On-Site Generation
Ozone water is most effective when it is generated as part of the system
Biofilm, slime, and odor often come back because the problem is inside the water path. Ozone water can help address recurring hygiene issues when it is built into the system where the problem occurs, not applied after the fact.
Limitations of chemical-only methods
Chemical-only approaches, including hypochlorous acid-based methods, can be labor-intensive and may not address the internal source of recurring problems.
Need for system integration
On-site generation makes ozone water available exactly where the application requires it.

FAQ
Questions from product and system developers
For engineering teams searching for an ozone water generator, the key question is not only the device itself, but how it can be integrated into the water path.
Can ozone water help address biofilm challenges?
Ozone water can support biofilm control when it is generated inside the water path as part of a system. Astozein modules are designed for applications where recurring biofilm, slime, and odor are issues.
What products can use ozone water generator modules?
Applications include water dispensers, handwashing equipment, cleaning robots, air conditioner water-management applications, food washing equipment, pressure washers, facility water systems, livestock water hygiene, and wastewater-related systems.
What is the difference between MARUS and RAIDEN?
MARUS is designed for compact embedded equipment, portable devices, and small-flow applications. RAIDEN is designed for fixed systems, larger-flow use cases, cartridge-based maintenance, and water infrastructure integration.
What type of water is required for the modules?
Astozein modules are designed for use with tap water within specified hardness and TDS ranges. Requirements depend on the module and operating environment.
Can the modules be integrated into existing water systems?
Yes. Astozein modules are designed to be built into products, equipment, and water systems. The appropriate configuration depends on water flow, installation space, power supply, and the target application. Contact us to discuss the best approach for your system.
What is the expected lifespan and maintenance requirement of the modules?
Expected operating life depends on water quality and usage patterns. Astozein provides module-specific specifications upon request. Contact us for details relevant to your target application.
