1016000-3 - Malabar 1016 Airbus A350 Coolant System Fill/Drain Cart

While the Malabar Model 1016 Coolant Cart does come with a 100’ power cord, a power plug is not supplied due to the various connection options available. The end user is responsible for selecting and installing the proper connector that matches their facility’s power supply. To ensure safety and compatibility, the installation should be performed by a qualified technician.

The coolant cart is filled with PGW fluid, which is a mixture of 60% propylene glycol and 40% water. This fluid is nontoxic; however, contact with the eyes may cause slight irritation, and repeated contact with the skin may cause flaking and softening. Inhalation of mist could lead to upper respiratory irritation. In rare cases, repeated exposure to propylene glycol could affect the central nervous system. Always refer to the MSDS for PGW fluid for detailed information on handling, storage, and toxicity.

The cart uses compressed nitrogen gas to purge the aircraft’s cooling system. When connecting nitrogen lines, caution is required, as the sudden release of compressed nitrogen can accelerate particles that could enter the eye or penetrate the skin. Always perform nitrogen purging in well-ventilated areas to minimize any risks.

Before loosening any tubes, hoses, or fittings, ensure the internal pressure is zero. Do this by turning off the main power disconnect selector switch or the purge valve located by the hose rack. This step is crucial to avoid accidents caused by pressurized fluid or gas release.

Always turn off the power before performing any maintenance to prevent accidental starts. When accessing the main and top-up motor shaft couplings or working near the generator cooling fan, ensure that no loose garments are worn that could get caught in moving parts.

To prevent static buildup or discharge, use the bonding cable included with the coolant cart. Connect the static cable to the aircraft’s grounding point to ensure proper dissipation of static electricity during operation.

Sight glasses are transparent tubes that allow operators to visually inspect the fluid levels in the cart’s reservoir tanks. This cart has sight glasses on each of the three tanks:

1. Clean Reservoir Tank: This tank holds the clean coolant that will be used to purge the aircraft’s cooling system.
2. Sub-Reservoir Tank: This tank may be used as a secondary reservoir for coolant or for collecting waste coolant.
3. Waste Reservoir Tank: This tank collects the used coolant after it has been purged from the aircraft’s cooling system.

By monitoring the fluid levels in these tanks, operators can ensure that the coolant cart is functioning properly and that sufficient coolant is available for the purging process.

A diesel generator set provides the necessary electrical power to operate the coolant cart's systems, particularly in environments where external power sources are unavailable or unreliable. The generator set ensures that the coolant cart can perform its primary functions, including circulating coolant, powering pumps, and maintaining system pressure, without relying on external electrical hookups.

No, the Malabar Model 1016 Coolant Cart is specifically designed for use with the Airbus A350 and may not be compatible with other aircraft types.

To ensure optimal performance and longevity of the coolant cart, it is crucial to adhere to a maintenance schedule that includes the following daily, quarterly, and annual tasks.

Daily Maintenance:

• Visually inspect the following components:
• Vacuum Trap: Drain if more than half full.
• Frame Structure: Check for loose nuts and bolts.
• Power Cord: Look for signs of wear or damage.
• Hoses: Inspect for wear or damage.
• Parking Brake: Engage the lock and verify the wheels are secured.

Quarterly Maintenance:

• Emergency Stop Button: Test by running the cart in run-around mode and pressing the emergency stop button. Discontinue use of the cart if the emergency stop button doesn’t function properly.
• Cart Hardware: Inspect hinges, latches, handles, and gas struts. Replace parts if needed.
• Sub-Reservoir Insulation: Check for tears or damage.

Annual Maintenance:

• Wiring: Check for loose connections and ensure all power terminal screws are tight.
• Electrical Enclosure Vent Filters: Inspect and replace as necessary.
• Steering, Parking Brake, and Wheel Bearings: Lubricate these mechanisms.
• Pressure Transducers: Calibrate for proper functionality.
