Bottom Loading Arms

OPW Bottom Loading Arm Systems are ideal for loading and unloading petroleum products, chemicals and liquefied gases, and offer numerous benefits over conventional top-loading systems:

  • Improved safety since operator remains on the ground during loading/unloading
  • Quicker connections reduce overall loading/unloading time
  • Bottom loading systems create less turbulence in the tank, reducing the danger of generating static electricity.
  • Bottom loading reduces vapors and the system can be adapted to also recover displaced vapors
  • Tanks can be filled faster and several compartments can be loaded simultaneously
  • Bottom-loading islands are simpler and cheaper to build than top-loading racks
