Bottom loading arms from OPW Engineered Systems and Liquip offer benefits not achieved with top loading designs. Bottom loading takes place on the ground, making it inherently safer for the operator. It also allows for simultaneous loading of several tank compartments, increasing speed and efficiency of loading. Bottom Loading arms can be connected via Ccam and groove fitting, dry disconnect, API coupler, or Acme threaded hammer union. Benefits of Bottom Loading Arm Systems: Safety of the person operating the loading arm is the prime advantage since the operator remains on the ground, not on top of the vehicle where falls are a common threat.A variety of bottom loadingunloading connections are made more quickly so overall loading time is reduced.Bottom loading systems create less turbulence in the tank, reducing the danger of generating static electricity.Bottom loading not only reduces vapors, which can be an environmental hazard, but this system can also be easily adapted to fully recover vapors displaced during loading.Bottom loading arms are simpler and less expensive to build than top loading racks. More savings are realized with bottom loading arms because youll safely load more material in a shorter time with less spillage and vapor loss. Arm-Tex offers a complete line of equipment for efficiently unloading and loading petroleum products, chemicals, and liquefied gases including LPG, LNG, and propane.
