The Tracer Wafer provides the perfect solution to the problem of introducing fluorescent refrigerant leak detection dye into production line situations. The Tracer Wafer is an absorbent substrate of inert material (the carrier) impregnated with a fluorescent leak detection dye. The wafer can be shaped into a profile that is convenient to handle and can be installed automatically into a component of the air-conditioning system, thus minimizing the labor required to incorporate the dye into the final package. It can also be introduced directly into the dryer or accumulator.A prime location for the Tracer Wafer is inside a desiccant bag within the receiverdryer or accumulatordryer of an air-conditioning system. AC system parts manufacturers are equipped to easily include Tracer Wafers in their products. Thats one reason why the Tracer Wafer is now being factory installed in new cars and trucks by auto makers in the U.S., Japan, Germany, the U.K., Italy, France, Sweden, China, Korea, Brazil and Mexico.
