Aircraft Oxygen Charging Unit

The Aircraft Oxygen Charging Unit is a specialized ground support equipment (GSE) designed to service and maintain aircraft oxygen systems efficiently and safely. This unit ensures that both military and commercial aircraft have a reliable supply of oxygen, essential for crew and passenger safety, especially during high-altitude flights or emergency situations.​

Technical Details:

1. Oxygen Storage and Capacity:

   • Cylinder Configuration: The unit typically accommodates multiple oxygen cylinders, with configurations ranging from two to four bottles, depending on operational requirements. 

   • Cylinder Capacity: Each cylinder generally has a capacity of 40 liters, allowing for substantial oxygen storage to service multiple aircraft without frequent refilling. ​

2. Pressure Specifications:

   • Maximum Pressure: The system is capable of delivering oxygen at pressures up to 3,000 psi (206.7 bar), suitable for various aircraft oxygen systems.

   • Adjustable Pressure Settings: Equipped with regulators that allow for precise control of outlet pressure, ensuring compatibility with different aircraft specifications.​

3. Mobility and Design:

   • Towable Configuration: Designed with a towable chassis, the unit can be easily transported across the airfield or within hangars, enhancing operational flexibility. 

   • Compact Dimensions: The compact and low-profile design facilitates maneuverability in confined spaces and ensures ease of storage when not in use.​

4. Safety Features:

   • Pressure Relief Valves: Integrated safety valves prevent over-pressurization, protecting both the equipment and operating personnel.​

   • Secure Cylinder Mounting: Features robust securing mechanisms to hold oxygen cylinders firmly in place during transportation and operation, minimizing the risk of accidents.​

5. Operational Components:

   • High-Pressure Hoses: Equipped with durable hoses capable of handling high-pressure oxygen transfer, ensuring reliability and safety during operations.​

   • Control Panel: User-friendly interface with gauges and controls for monitoring and adjusting pressure, facilitating straightforward operation by ground personnel.​

Applications:

• Routine Maintenance: Used during scheduled maintenance checks to replenish aircraft oxygen systems, ensuring they are fully operational for upcoming flights.​

• Emergency Servicing: Essential for rapid oxygen system servicing in response to unscheduled maintenance needs or after in-flight oxygen system deployment.​

• Pre-Flight Preparation: Ensures that aircraft oxygen systems are adequately charged before flights, particularly for high-altitude operations where supplemental oxygen is critical.​
