Receiver Dryer: Description and Operation

Tracing Agent Fluorescent, Production/after Market

Tracing agent fluorescent, production

The tracing agent is impregnated in a free standing "Dry-Water" cylindrical filter in the drying agent in the receiver.
The tracing agent dissolves and mixes with the A/C compressor oil in the climate control system. The tracing agent is light green in color. It is used to identify any leakage in the climate control system. If an UV lamp is used, it is easier to see where the fluorescent tracing agent is leaking out.
To fill with refrigerant, see: Refrigerant, filling.
To trace leaks, see: Leak detection, tracer agent or: Leak tracing, electronic leak tracer.
