CHEM-ROD® Low-Impedance Chemical Grounding Electrode

An efficient grounding system is critical to personnel safety and uninterrupted operations. However, conventional ground rods are typically insufficient for industrial uses where target resistance can be less than 1ohm.

The Chem-Rod solves problems found with conventional ground rods by requiring less real estate and fewer electrodes to meet specified resistance.

Each Chem-Rod creates an optimal electrical connection to earth with a large conductive surface. The earth / electrode interface is further enhanced by conductive backfill and electrolytic salts, ensuring a consistent path to ground. Engineered to meet applicable design and safety standards, the Chem-Rod is uniquely suited for both general grounding and as the foundation of a complete lightning protection system.

The Chem-Rod uses advanced engineering to achieve a consistent, low-impedance electrical connection with the earth, even in unfavorable and varying ground conditions, such as permafrost.

High-frequency transient events like lightning force the current flow to the surface of an object. In these events, electrodes with more surface area have less impedance. A copper Chem-Rod has about four times more surface area than a traditional ground rod. This larger surface area helps create the low-impedance connection required to safely channel high-frequency lightning currents to earth.
