• Built‑in Filtration System：Automatically filters impurities in the water, ensuring cleaner water quality and protecting the entire pipeline system.

• High Efficiency & Energy Saving：Operates stably with low energy consumption; full‑automatic circulating treatment reduces manual operation costs.

• Safe & Environmentally Friendly：No harmful chemical residues; safe for daily water use and environmentally compatible.

• Residential areas, apartments, villas, and hotels domestic water tanks

Suitable for daily drinking water safety, the external installation avoids damaging tank structures and affecting water supply. It realizes 48-hour continuous sterilization (99.9% rate) to purify water, improve taste, and reduce manual maintenance costs for property and hotels.

• Office buildings, schools, hospitals, shopping malls, and stadiums secondary water supply systems

Adapts to high water consumption and strict water quality requirements in public places. It continuously purifies water, controls pathogenic microorganisms (e.g., Legionella), and is easy to retrofit without occupying much space.

• Fire water tanks, swimming pools, and water circulation systems

Prevents stagnant fire water from contamination and pipeline blockage, ensures swimming pool water safety without chemical residues, and avoids scaling/corrosion in circulation systems to extend service life.

• Agricultural irrigation water storage facilities

Disinfects irrigation water to eliminate harmful microorganisms, adapts to outdoor agricultural environments with easy installation, and helps farmers reduce production costs while ensuring irrigation water quality.

• Industrial circulating water tanks and water storage equipment

Improves water anti-scaling performance, avoids pipeline blockage and equipment corrosion, adapts to various industrial fields, and can be customized to ensure stable production and reduce water-related losses.

Usage Methods

• Install the main and auxiliary units outside the water tank and connect the circulation pipeline correctly.

• Turn on the power; the main unit will automatically send working signals to the auxiliary unit.

• The electrolysis system starts to generate high‑oxidation disinfection substances.

• The circulation pump continuously draws water from the tank for treatment and returns purified water to the tank.

• The equipment runs automatically to maintain long‑term clean and safe water quality.

Safety Precautions

• Installation and wiring must be performed by professional electricians or technical personnel.

• Do not disassemble the host or auxiliary unit without permission to avoid electric shock or equipment damage.

• Keep the equipment dry and prevent water from entering the internal electrical parts.

• Regularly check and clean the filter element to ensure normal water flow and treatment effect.

• Keep the equipment away from flammable and explosive materials.

• In case of abnormal noise or failure, cut off the power immediately and contact professional maintenance.

FAQ

• What are the application scenarios for external tank sterilizers?

External tank sterilizers are widely used in domestic water tanks in communities, villas, hotels; secondary water supply systems in office buildings, schools, hospitals; fire water tanks, swimming pools, agricultural irrigation systems, and industrial water storage equipment.

• What is the difference between external and internal tank sterilizers?

External sterilizers are installed outside the tank, easier for retrofitting, maintenance, and later management. Internal sterilizers are installed inside the tank, saving external space. Users can choose according to installation environment and space conditions.

• Can the equipment be customized?

Yes, we support customized design according to tank volume, water quality, installation space, flow requirements, and special working conditions.

• Are you a manufacturer or a trading company?

We are a professional manufacturer integrating R&D, production, and sales of water treatment equipment, with independent production capacity, technical support, and after‑sales service system.

• How long does the sterilization effect last?

The equipment provides continuous and stable disinfection; the effective sterilization duration can last up to 48 hours, maintaining long‑term clean water quality.

• Does this product require frequent maintenance?

No. It is designed for automatic operation. Only regular filter cleaning and routine inspection are needed, with low maintenance cost and simple operation.
