The system may be used for virtually any application where the protection of machinery, electronics, and personnel is important. Terra Dyne® EGS was designed for use in any type of soil condition. Some of the many applications where it is commonly used include cellular, radio and television broadcasting sites, computer facilities, power substations, communication centers, medical facilities and industrial plants. The electrodes vary in length from 8 to 300 feet. Custom lengths, accessories and design options are available. Protecting your expensive equipment is essential.

Terra Dyne® Electrolytic Grounding System is a multipurpose grounding system. It has been designed to provide long term protection from lightning, electrical transients, static discharges, electro-magnetic interference and other electrical hazards.
Terra Dyne EGS is guaranteed for 30 years, with an expected life of at least 50 years. The systems are available in vertical or horizontal models.
Vertical electrodes are usually installed using an augur or other drilling equipment. Horizontal electrodes are installed in trenches and utilized where the soil is rocky or excavation conditions are poor.
Terra Dyne® Electrolytic Grounding System enhances the performance of your electronics, stabilizes signal references and reduces the risk of injuries.
Lower resistance/impedance achieved with fewer rods.
Maintains low resistance in changing temperature and soil conditions.
Cost-effective for reaching target resistance at large sites or where space is limited.
Service life of over 30 years with no increase in resistance when properly maintained.
Designed for easy inspection and refill.
An efficient grounding system is critical to personnel safety and uninterrupted operations. But conventional ground rods are typically insufficient for industrial uses where target resistance can be less than 1 ohm.
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 is an ultra-efficient grounding electrode designed to provide the optimal low-resistance, low-impedance interface with earth.
High-frequency transient events like lightning force 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.
The damage caused by a single lightning strike or stray current can cost millions in equipment losses, downtime, and personnel injury.
The Chem-Rod can reduce these risks more effectively than other ground rods by providing the most efficient earth interface. In addition, it meets or exceeds relevant design codes and safety standards for protection of personnel, property, and sensitive equipment.
The ultra-efficient Chem-Rod has been used to replace as many as 10 conventional rods. (Conversion depends on soil conditions and other factors.) Using Chem-Rods in place of traditional rods often results in lower overall costs and improved protection, especially in areas with limited earth available for grounding. As grounding standards have evolved to require lower resistance levels, better electrodes are needed. While old methods may have been adequate for grounding to 25 ohms, using the same methods to reach 1 ohm or even 5 ohms can be impractical if not simply impossible. An optimized grounding electrode like the Chem-Rod can reach lower resistance levels with fewer electrodes than traditional methods, making it a more effective solution.
A recent NEGRP study tested 15 different types of grounding electrodes including the horizontal Chem-Rod and vertical Chem-Rod. The test included 8 years of analysis at five U.S. sites with results verifying that the Chem-Rod consistently provided the lowest resistance of all models tested.

The Chem-Rod achieves superior results wherever it can be buried in the earth: indoors or outdoors, in sandy soil or permafrost, even in or beneath concrete slabs.
The vertical Chem-Rod is installed in an augured hole. Where augering deep holes is impractical, such as in rocky soil, the horizontal configuration is installed in a shallow trench. Both configurations come filled with electrolytic salts and, as a final step, are backfilled with a mixture of GAF and native soil to achieve the maximum electrical connection to earth.
