Cargo ventilation dampers in marine HVAC systems regulate airflow within ship cargo holds. They ensure proper air exchange to prevent moisture buildup and maintain cargo quality. These dampers are designed to withstand harsh marine environments and ensure operational efficiency.

Size: Typically ranges from 100 mm to 1000 mm in diameter or equivalent rectangular dimensions.

Grade: Marine-grade stainless steel (316L) or galvanized steel for corrosion resistance.

Viscosity: Not applicable (N/A) as dampers are mechanical components.

Buoyancy: Not applicable (N/A) as dampers are installed in fixed HVAC systems.

Material: Stainless steel (316L), galvanized steel, or aluminum for lightweight applications.

Operating Temperature: -20°C to +80°C (-4°F to +176°F).

Pressure Rating: Up to 1000 Pa (10 mbar) depending on design.

Flame Resistance: Compliant with IMO FTP Code for marine safety.

Sealing: Rubber gaskets or silicone seals for airtight closure.

Actuation: Manual, electric, or pneumatic operation options.

Airflow Capacity: Adjustable, typically 500–10,000 m³/h based on size.

Corrosion Protection: Powder coating or marine-grade finishes.

Standards: Complies with ISO, SOLAS, and marine HVAC regulations.

Cargo Ventilation Dampers and Marine HVAC systems typically comply with maritime standards such as SOLAS, IMO regulations, and classification society rules like ABS, DNV, or Lloyd's Register.
