Dräger X-am 5000 Multi Gas Detector & 8318639 Lademodul Charger Kit

Dräger GS-1258 / X-am 5000 Multi-Gas Detector with Lademodul 8318639 Charging Cradle

Engineered for harsh shipboard, offshore, and industrial environments, the Dräger GS-1258 / X-am 5000 Multi-Gas Detection System delivers simultaneous monitoring of up to 5 hazardous gases, including combustible hydrocarbons, Oxygen, Hydrogen Sulfide, Carbon Monoxide, and specialized toxic vapors. Paired with the dedicated Dräger Lademodul (MPN: 8318639) desk/wall charging cradle, this package provides a dependable power architecture for continuous field deployment.

From an operational engineering perspective, the X-am 5000 is built with a dual-entry gas diffusion path to eliminate false readings caused by pocket obstruction or directional airflow blockage. Combined with Dräger’s catalytic CatEx and XXS miniaturized electrochemical sensor architecture, this unit fulfills the strict atmospheric testing criteria required under SOLAS Regulation XI-1/7 and IMO MSC.1/Circ.1477 for enclosed space entry drills and cargo tank monitoring.

Technical Specifications

Key Features

1. Zero-Poison Catalytic Sensor (CatEx 125 PR): Delivers superior resistance to silicone vapor contamination and hydrogen sulfide H2S passivation, maintaining calibration accuracy in fuel tanks and engine room bilges.
2. True IP67 Submersion Rating: Heavy-duty rubber overmold protects the unit against salt spray, vibration shock, and accidental submersion in water or deck run-off.
3. Rapid Multi-Chemistry Charging (Lademodul 8318639): Intelligent voltage regulator circuitry prevents cell degradation and thermal overload, bringing the internal NiMH pack to full charge in under 4 hours.
4. SOLAS XI-1/7 Enclosed Space Compliance: Fully engineered for 4-gas and 5-gas standard testing requirements before entering ballast tanks, pump rooms, cargo holds, and cofferdams.

Primary Applications

• Marine & Offshore Operations: Pre-entry clearance testing for ballast tanks, fuel oil tanks, cargo holds, pump rooms, and chain lockers.
• Petrochemical & Refinery Facilities: Personal perimeter monitoring during hot-work turnarounds, inert gas plant operation, and pipeline repairs.
• Municipal & Industrial Utilities: Sewer maintenance, wastewater vault inspections, sump monitoring, and chemical dosing facilities.
• Mining & Heavy Tunneling: Atmospheric evaluation in mine drifts, shafts, and extraction sites subject to CH4 and toxic combustion byproducts.

Chief Engineer’s Calibration & Daily Check

On a vessel or industrial site, a gas detector is life-critical safety equipment. Never skip your daily bump test.”

1. Verify Sensor Clear Air Baseline: Always perform your clear-air zero adjustment in fresh outdoor air—never on the engine room floor plates or down in the cargo control room where trace refrigerant or hydrocarbon vapors can skew the zero-reference point.
2. Terminal Contact Maintenance (8318639 Cradle): Marine environments accelerate copper and brass oxidation. Regularly clean the charging pins on both the 8318639 cradle and the base of the X-am 5000 using an electrical contact cleaner and a lint-free swab. Never use abrasive emery cloth, as it strips the gold-plated contact layer.
3. Pre-Entry Sampling Technique: When conducting remote sampling of cargo tanks or double bottoms using an external sampling hose, remember the 3 seconds per meter rule. If you are using a 15-meter sample line, wait at least 45 seconds plus the sensor response time before recording the tank atmosphere parameters.

Frequently Asked Questions

Can the Dräger Lademodul 8318639 be powered directly from a 24V marine bridge bus?

Yes. The 8318639 charging cradle features internal input regulation rated for wide DC ranges (12 VDC to 24 VDC nominal), making it suitable for direct hardwiring into shipboard low-voltage DC switchboards or vehicle battery systems using the appropriate fused adapter harness.

How often should the CatEx and XXS electrochemical sensors be calibrated?

Under normal operating procedures, a bump test should be conducted prior to each day’s use. Full span gas calibration is recommended every 6 months (or every 12 months for standard electrochemical sensors depending on company safety management systems and flag state requirements).

What is the primary difference between the X-am 5000 and X-am 5600?

The X-am 5000 utilizes a catalytic bead sensor (CatEx) for combustible gas detection, which requires at least 10% to 12% ambient oxygen to function properly. The X-am 5600 utilizes an optical Non-Dispersive Infrared (NDIR) sensor, which can measure explosive hydrocarbons even in completely inert, oxygen-depleted atmospheres.

Is it safe to charge the X-am 5000 within an explosive or hazardous zone?

No. The Lademodul 8318639 charging cradle is not an explosion-proof assembly. Charging operations must strictly be carried out in safe, non-hazardous areas such as the vessel’s workshop, ship’s office, or control room.
