At Qualships PTY Australia, we recently carried out a comprehensive overhaul of a ship’s air conditioning system, ensuring peak performance and reliability for critical onboard climate control. Our expert marine technicians executed a complete service plan, including condenser overhaul, compressor renewal, system vacuuming, refrigerant gas charging, and a thorough leak test. Scope of Work: 1. Condenser Overhaul: The ship’s AC condenser unit was dismantled, inspected for corrosion, cleaned thoroughly, and pressure-tested to confirm structural integrity. Necessary seals and gaskets were replaced, ensuring efficient heat exchange and preventing future failures. 2. Compressor Renewal: The aging AC compressor was removed and replaced with a new, high-performance marine-grade compressor. All connections were aligned and torqued as per OEM specifications, ensuring proper alignment and vibration-free operation. 3. System Vacuuming & Dehydration: Using our state-of-the-art vacuum pump setup, the entire refrigeration circuit was evacuated to remove moisture and air pockets. This process is critical in preventing internal corrosion and ensuring the longevity of AC components. 4. Refrigerant Gas Charging: The system was charged with R-134a refrigerant as per the correct volume and pressure parameters. We ensured the system pressure matched operating specs, securing optimal cooling performance across all cabins and control rooms. 5. Leak Test & Final Inspection: A comprehensive leak test using nitrogen and soap solution was conducted, followed by an electronic leak detector scan. No leaks were detected, and the system was declared operationally sound. ⸻ This major AC system overhaul was completed successfully with zero downtime and no refrigerant loss, meeting Class and Owner satisfaction.
