REAL Alternatives Module 2 Design Differences for Alternative Refrigerants | 5 Minimising Leak Potential Irrespective of the refrigerant it is important that leak potential is minimised, therefore:  Keep it simple;  Minimise the number of joints;  Minimise the number of components;  Close couple the system;  Minimise the operating and standstill pressures;  Minimise the number of access points to the system and locate them where they are most useful;  Avoid using Schrader valves, but if an access valve is absolutely necessary use a ball valve with a flare connector (and ensure it is capped when not in use);  Avoid using open drive compressors where possible. If they must be used, ensure that they have shaft seals;  Ensure pipe is correctly clamped and vibration transmission is eliminated;  Provide information:  Showing the location of access points on the isometric drawing in the plant room;  On torque values;  Design in ease of service to aid leak detection and other vital maintenance activities. See REAL Alternatives Guide 3 “Containment and Leak Detection”
