3 Direct Strike Protection Pentair'

s innovative technology provides two systems for capturing lightning energy. The ERICO SYSTEM

2000 provides conventional air terminal technology to meet traditional needs. An alternative approach to lightning protection is the ERICO SYSTEM 3000, which utilizes the collection volume principle to determine the effective placement of lightning protection to ensure the safe conveyance and dissipation of the lightning energy into the ground. Over

7000 facilities, including some of the tallest and most vulnerable buildings in the world, are protected by ERICO SYSTEM

3000 from Pentair. Facility Electrical Protection for the 21st Century ? Well known technology of passive rods or air terminals, familiar to installers ? Air terminals available in aluminum, copper and stainless ? IEC? , B.S., and U.S. Standard Compliant ? Precision manufacturing helps ensure easy assembly and installation ? Computer-aided design to IEC62305, NFPA? -780, AS/NZS1768 ? Advanced lightning protection system based on latest lightning research and technology ? Enhanced area of protection, fewer air terminals needed ? Economical and easy to install ? Fewer downconductors are required ? Designed to protect all types of structures and open areas ? Computer-aided design using Collection Volume method Grounding and Bonding For the efficient performance of a lightning protection system, it is essential that a low impedance ground be provided to facilitate the dissipation of the lightning energy into the earth mass. Because soil conditions and seasonal patterns vary from site to site, the methods of grounding need to be considered on an individual basis. As a grounding specialist, Pentair provides a range of grounding systems to suit any application. Pentair offers a variety of products, such as ground bars, signal reference grids, ground plates and potential equalization clamps, which are designed to create an equipotential plane and help protect personnel and valuable equipment. ERICO copper-bonded or stainless steel earth rods and GEM facilitate the transfer of surges and fault currents into the earth, and provide a very long service life due to superior construction and quality. Connections are often the most critical element of grounding systems, so the preferred method of connection is the CADWELD exothermic welding process.
