UV black lights are used in conjunction with UV fluorescent tracer additives to quickly detect fluid leaks and pinpoint their exact source.


The UV fluorescent additive is mixed with a fluid system, e.g. water, oils, fuels, coolants and refrigerants. The equipment is then operated as normal to allow the fluorescent additive to circulate throughout. Where a leak occurs the UV fluorescent tracer escapes with the fluid and remains at the site of the leak and along the flow path. Inspection under UV black light of all external surfaces, pipework, joints, connectors, gasket seals and coils will reveal the leak location and flow path as a bright fluorescent yellow/green glow.


This process can be used for routine quality control or trouble shooting procedures and offers vastly improved probability of fluid leak detection.
