Abstract: Provided is a porous pellet for inclusion into an operating fluid of a fluid system for detecting sites of fluid leakage. The porous pellet comprises a solid matrix formed by at least one fluorescent dye which is solid at room temperature. The matrix has a porosity of from about 10% to about 90%. Methods of installing the porous pellets into fluid system for detection of leaks is also provided.

Abstract: An evaporator cuff for use with a pipe freezer apparatus. The evaporator cuff includes a hose connector attached to an evaporator body. The evaporator body has an inner wall configured to engage the outer surface of a pipe, an outer wall spaced apart from the inner wall. A chamber is defined between the inner and outer walls, first and second side walls, and first and second end walls. A plurality of baffles are located in the chamber and arranged to define a series of conduits for creating a flow path through the chamber for refrigerant to flow along. The walls are arranged so as to form a serpentine flow path from the evaporator inlet to the evaporator outlet.

Abstract: A process for applying a fluorescent leak detection dye to a component of an air conditioning system. The process involves the steps of (i) providing a fluorescent dye that is solid at room temperature, (ii) exposing the dye to an elevated temperature to melt the dye into a liquid or flowable state, (iii) injecting, channeling, spraying or placing the flowable dye into or on a component or an HVAC or A/C system, (iv) allowing the dye to resolidify in or on the component, (v) attaching the component to the HVAC or A/C system, and (iv) dissolving the resolidified dye in a liquid/gas.
