Oxygen Scavengers - Hose Couplings and Petroleum Products
Oxygen scavengers are water-treatment chemicals used in marine boiler feedwater and closed hot-water systems to remove dissolved oxygen and reduce corrosion. Common chemistries include sodium sulfite, DEHA, carbohydrazide, and related formulations.
ProShipWorks provides end-to-end support to source and supply Oxygen Scavengers for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval
Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.
| Applicable Standards & Certification | Product-specific safety data sheets and chemical handling requirements apply. Boiler-water treatment should follow the equipment manufacturer’s instructions and applicable flag-state, vessel-management, and environmental requirements. |
|---|---|
| Class Approval | Oxygen scavenger chemicals are generally not individually type-approved by DNV, ABS, Lloyd’s Register, BV, or ClassNK. Acceptance may depend on the vessel’s approved water-treatment procedure and equipment requirements. |
Installation, Maintenance & Safety Information
| Installation Notes | Dose through a suitable chemical injection point, normally into the boiler feedwater or condensate system. Use supplier instructions, system volume, dissolved-oxygen readings, and boiler-water test results to establish dosage. |
|---|---|
| Maintenance Tips | Monitor dissolved oxygen, sulfite or residual scavenger, pH, conductivity, and boiler-water chemistry at the recommended frequency. Store containers sealed in a cool, ventilated area and prevent contamination. |
| Safety Notes | Review the product safety data sheet before use. Wear chemical-resistant gloves, eye protection, and suitable protective clothing. Avoid contact with skin and eyes, do not mix incompatible chemicals, and provide ventilation during handling. |
