Electrostatic gas discharges are prevented in a controlled manner through the use of Eltex active ground monitoring systems.
Grounding of large containers during filling or emptying
Conductive drums into which a solvent is pumped or removed must be grounded!
Electrically conductive drums are filled or emptied with a solvent-containing liquid.
Can electrostatic discharge occur as a result of filling the liquid into the container?
In the companies, the solvents or solvent-based ink are delivered in large conductive containers or barrels. When the solvent content is pumped, mixed or stirred, a good ground connection must always be made to prevent a spark discharge and fire. Since the containers are mobile, it can happen that an operator forgets to connect a grounding clamp and starts the process without grounding.

Which Eltex components are used?
Active grounding clamps
The active Eltex grounding clamps from the TERRACLAMP and the 70 series are used together with the TERRALIGHT and the Terra-Control TUE30 ground monitoring system to establish and monitor grounding connections. These devices are used when decanting or filling potentially explosive substances. Existing electrostatic changes are discharged effectively in a controlled manner. The active grounding clamps from the TERRA-C/S, TERRA-C/B, 70AK and 70HK series feature extremely hard and sharp collet jaws. The jaws also feature a continuously high clamping force, ensuring a secure connection to the equipotential bonding at all times. The standard version of the grounding clamps includes a plug-in-connector for an easy connection to the included grounding cable, spiral cable and rewinding cable reels.
TCB030
Terrabox TCB030 is designed for direct installation in explosion hazard areas and for connecting a clamp. Two clamps are connected when used for BIG BAG grounding. The dual-color indicator lamp signals the correct grounding state. The integrated contacts allow an enable circuit to be implemented.
