Description

Building on Dairyland's industry-leading product lines, the PCRX represents the next technological leap forward in decoupling technology. Using sophisticated design techniques that represent the work of numerous leading experts around the world, the PCRX’s new camouflage technology renders it virtually invisible to interrupted survey testing. Like our other decouplers, the PCRX is a solid-state, maintenance-free device designed to simultaneously provide DC decoupling and AC continuity/grounding when used with cathodically protected structures, such as pipelines, tanks, grounding systems, and cable casings. Commonly used to decouple electric equipment from grounding systems, for AC mitigation projects, or other isolation and grounding applications, the PCRX provides safety grounding while also isolating your cathodically protected structure, improving CP system performance.
