Air Dryers - Auxiliary Machinery and Engine Room

Marine air dryers remove moisture, oil aerosols and contaminants from compressed air used for starting, control, instrumentation and service systems. Refrigeration or desiccant technology prevents corrosion, freezing and pneumatic equipment failure in engine-room environments.

ProShipWorks provides end-to-end support to source and supply Air Dryers 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 Performance and compressed-air quality are commonly specified using ISO 7183 and ISO 8573-1. Pressure vessels and piping may require PED, ASME Section VIII or applicable flag-state rules, depending on installation and operating pressure.
Class Approval Marine installations may require approval by DNV, ABS, Lloyd's Register, Bureau Veritas or ClassNK. Approval is package-, vessel- and project-specific; verify the selected dryer, pressure vessels and controls against the vessel's class requirements.

Installation, Maintenance & Safety Information

Installation Notes Install downstream of the compressor receiver and separator with correctly sized pre-filters, after-filters, isolation valves, bypass and condensate drains. Maintain specified airflow direction, ventilation, operating pressure and service clearance.
Maintenance Tips Inspect drains and filters regularly, monitor pressure drop and dew point, and replace filter elements and desiccant at manufacturer intervals. Clean refrigeration condensers and check valves, seals, refrigerant circuit and purge operation.
Safety Notes Isolate electrical power, depressurize and lock out the system before maintenance. Never open filters or desiccant vessels under pressure. Use rated piping and relief devices, and handle refrigerants and condensate according to applicable safety and environmental rules.
