• R-134a: Suitable for medium and high-temperature applications, serving as a long-term replacement for R-12.
• R-404A: Suitable for low and medium-temperature applications.
• R-407C: A replacement for R-22, suitable for medium and high-temperature applications.
• R-410A: Twice as efficient as R-22 but generally recommended for new systems only.

During Normal Operation:

• Implement a robust monitoring system with daily logs of key parameters to allow for early detection of any anomalies, such as pressure drops or temperature fluctuations, that might indicate a leak.
• Regular Leak Detection: Conduct routine leak tests to identify leaks from joints, seals, gaskets, pipes, and other components.
• Safety Valve Management: Ensure correct setting and operation of safety valves to prevent accidental refrigerant release.

During Maintenance Activities:

• Mandate the complete recovery and recycling of refrigerant gas before any maintenance work commences. Utilize onboard recovery systems, ensuring they are properly maintained and calibrated.
• Implement procedures to minimize refrigerant venting during maintenance, utilizing capturing and recovery techniques wherever possible.
• Provide comprehensive training to all maintenance personnel on proper handling, recovery, and recycling procedures for refrigerants.
• Maintain a clean, dry system to prolong mechanical seal effectiveness and prevent leaks. Avoid excessive water pressure in the condenser to prevent tube failures. Monitor machinery vibration to prevent damage that could lead to gas leaks.
• Use leak-proof connections for charging and recovery, employing compatible and manufacturer-specified gaskets and mechanical seals. Ensure all refrigerant is recovered before opening the system for maintenance.
• Use geniune Spare parts to avoid any failure of system leading to accidentally release of gas.
