Which tool is commonly used for capturing refrigerant during recovery?

The use of a recovery cylinder is essential in the refrigerant recovery process, as it is specifically designed to safely store and contain refrigerants removed from the system. The recovery cylinder allows technicians to collect refrigerant without releasing it into the atmosphere, thus following environmentally friendly practices and complying with regulations regarding refrigerant emissions.

The recovery process involves transferring the refrigerant from the system into the recovery cylinder, where it can be stored until it can either be recycled or disposed of properly. Recovery cylinders are built to withstand the pressures associated with the refrigerants, ensuring safe handling and preventing leaks.

In contrast, a vacuum pump is used to remove air and moisture from the refrigeration system before charging it with refrigerant, not for capturing refrigerant itself. Pressure gauges help technicians monitor system pressure and diagnose issues, but they do not capture refrigerant. Similarly, a thermometer measures temperature but does not play a role in refrigerant recovery. Thus, the recovery cylinder is the appropriate tool for refrigerant capture due to its specialized design and functionality.
