Benefits

  • Very low-ohmic measure line, especially for maritime application
  • Opening of the housing during operation in hazardous areas is allowed
  • 2 clearly visibly LEDs at the device front
  • Easy check of a proper grounding connection due to status LEDs at the grounding clamp
  • Usage under extreme environmental conditions (sturdy stainless steel housing with IP 65) and wide temperature range (-40 °C to +60 °C)
  • Over 30 years of experience with Marine Grounding Systems

  • Effective potential equalization between ship and shore prevents possible formation of sparks and hot spots
  • Highest safety by interruption of the battery effect (galvanic cell) between ship and shore
  • Automatic shut off of product flow, when grounding is interrupted
  • Explosion protection for worldwide use according to IECEx and the European ATEX directive 2014/34/EU (zone 1) – IECEx approval not yet finalized –
  • As absolutely essential safety component even when insulating flanges are used
  • Various control outputs, e.g. for connection to an additional status indicator to display an unsafe status
  • Marine Grounding Clamp with 2 integrated status LEDs
  • Effective failure diagnosis by integrated system information display (incl. 10 status-LEDs)
  • Object recognition of the ship
  • The electrical conductive bonding line connection between ship and shore is released, after a proper mechanical and electrical contracting is monitored
  • Detection of incorrectly connected clamp or pull off and immediately switching into safe status
