Multi-Channel Static Earthing System


The Earth-Rite® MULTIPOINT II is an innovative multi-channel static earthing system that can monitor the simultaneous earthing of up to eight unique pieces of equipment at risk of discharging electrostatic sparks.

To earth and monitor multiple items of equipment at points like multi drum loading stations and mixing stations, IBC loading stations and railcar loading gantries, a large number of conventional static earthing systems would be required to provide protection against incendive electrostatic sparks. In addition to flammable liquid and gas operations, powder processing equipment that typically includes interconnected pipes, fluid bed dryers, hoppers and micronizers would require multiple earthing systems. With the Earth-Rite® MULTIPOINT II up to eight individual items of potentially isolated equipment can be earth monitored simultaneously with a single static earthing system.
Earth-Rite® MULTIPOINT II applications include:

  • multiple railcar loading points
  • multiple drum / tote loading points
  • liquid / powder mixing and blending
  • powder conveying equipment
  • fluid bed drying
  • silo / container filling and emptying
  • hoppers and dust collectors
  • powder micronizing, pulverising and grinding equipment

The Earth-Rite MULTIPOINT II multiple static earthing system is ATEX / IECEx / cCSAus certified which identifies when equipment exceeds earth resistance levels outlined in codes of practice including CLC / TR 60079-32-1 and NFPA 77. The system consists of a hazardous area monitoring unit that contains eight pairs of red and green LED indicators that verify when the equipment at risk of static charge accumulation has a resistance of 10 ohms or less to the plant’s designated true earth grounding point.
