CA-Fire MN65 Series Marine-Grade Aluminum Fire Nozzle

(Salt-Resistant & Vibration-Proof Water Jet Tool for Shipboard Fire Safety & Maintenance)

 

1. Product Name & Positioning

 

Full Name: CA-Fire MN65 Series Marine-Grade Aluminum Fire Nozzle (7bar Operating Pressure, 5-12L/S Flow Range, 65mm Marine Standard Coupling, Salt-Spray Resistant)

Abbreviation: CA-Fire MN65 Marine Fire Nozzle

Core Positioning: A specialized shipboard water jet tool engineered for marine environments-radically different from the previous QLD6.0/13III-C general-purpose high-pressure nozzle. It's tailored to withstand saltwater corrosion,ship navigation vibration and limited onboard space, integrating fire suppression and deck maintenance functions. Made of marine-grade aluminum with enhanced sealing and anti-corrosion design, it fills the gap of "marine-specific adaptability"-ideal for cargo ships,passenger vessels,offshore platforms and port emergency teams.

 

2. Core Product Advantages

 

1. Marine-Grade Anti-Corrosion: Withstand Saltwater & Humidity

Unlike the general-purpose nozzle (standard aluminum with basic anti-rust coating), this marine model prioritizes saltwater resistance:

Body material: Marine-grade 6061 aluminum alloy (tensile strength ≥276MPa) with triple anti-corrosion treatment-chromate conversion coating + epoxy primer + polyurethane topcoat. Passes 1000-hour salt spray tests (vs. 300 hours for the general-purpose model), no rust or degradation in long-term saltwater exposure.

Sealing system: Uses marine-specific nitrile rubber gaskets (resistant to saltwater,oil and grease), avoiding leakage caused by salt crystal buildup (a common issue with general-purpose nozzles on ships).

2. Vibration-Proof Structure: Stable for Ship Navigation

Addressing the vibration challenge of shipboard use (general-purpose nozzles lack such design):

Reinforced handle & coupling: The handle is wrapped with shock-absorbing rubber, and the coupling features a locking sleeve to prevent disconnection during ship sway (±15° tilt resistance). The general-purpose nozzle's standard coupling may loosen under vibration.

Internal component fixation: Valve core and flow control parts are secured with anti-loosening screws, avoiding performance deviation from vibration-ensuring consistent flow rate even in rough sea conditions.

3. Dual-Function for Marine Needs: Fire Suppression + Deck Maintenance

Optimized for ship-specific tasks, beyond the general-purpose nozzle's single high-pressure focus:

Fire suppression: 5-12L/S flow covers shipboard Class A/B fires (e.g., cargo hold wood fires,engine room oil spills). The water jet's penetration power is adjusted for confined spaces (e.g., cabins) to avoid water damage to equipment.

Deck cleaning: Low-mid flow (5-8L/S) removes salt crust,oil stains and marine organisms from decks/hulls-compatible with both seawater and freshwater (general-purpose nozzles may clog with seawater).

4. Compact & Lightweight: Adapt to Limited Onboard Space

More space-efficient than the general-purpose nozzle (2.7kg) for shipboard storage:

Net weight ≤2.3kg: 15% lighter, easy to carry between ship decks or store in narrow fire cabinets. The ergonomic handle fits gloved operation (common in marine environments), unlike the general-purpose nozzle's wider grip.

Streamlined design: No protruding parts, reducing collision risks during storage or transportation on crowded ships.

5. Marine Standard Coupling: Direct Fit for Ship Fire Systems

Unlike the general-purpose nozzle's 65mm industrial coupling, this model uses marine-standard 65mm flange/coupling:

Compatible with global ship fire pipeline standards (e.g., IMO,SOLAS), no adapters needed for shipboard hydrants or fire pumps. The general-purpose nozzle may require custom adapters for marine use, increasing leakage risks.

5. Frequently Asked Questions (FAQ)

 

Can it be used with seawater for long periods?Yes. The marine-grade aluminum body and saltwater-resistant seals are designed for prolonged seawater use-no clogging or corrosion. After seawater use, rinse with freshwater once a month to extend service life.

How does it adapt to confined ship spaces (e.g., small cabins)?The flow control's low setting (5L/S) produces a focused, non-splashing jet-penetrates fire without spreading water to sensitive equipment. The compact design allows operation in narrow gaps, unlike the bulkier general-purpose nozzle.

Is it compliant with international marine safety standards?Yes. It meets IMO (International Maritime Organization) and SOLAS (Safety of Life at Sea) requirements, certified for use on commercial ships globally. The general-purpose nozzle lacks marine-specific certifications.

What's the difference in maintenance from the general-purpose model?Marine use requires monthly freshwater rinsing (vs. quarterly for general-purpose) and annual seal replacement (saltwater accelerates wear). We provide a marine maintenance kit (MOQ 50 units) with specialized cleaning tools and replacement seals.
