Rail Tank Car Mixing

When your product show up in a railcar tanker during the dead of winter and the contents need to be heated and thawed out, the Pulsair mixing process can help reduce the time it takes to heat up the contents before they can be pumped out. Mixing rail tank cars with a Pulsair mixing system along with steam coil heating can greatly lower your energy costs up to 50% and significantly decrease the unloading time. Pulsair offers the most overall cost-effective method to mixing tank rail cars. The Pulsair mixing system is also an excellent choice to mobilize and "knock down" waste heels during tank cleaning and remediation. For some tank rail car contents, the products must be heated by steam coils continuously until the liquid contents reach the appropriate pumping temperature. Pulsair accelerates the heat transfer thoughout the tank's contents by sequentially injecting air into the tanks either through the bottom operating valves or through the top opening. This quickly moves the heated materials away from the steam coils preventing it from scorching or burning and allowing it to accelerate the transfer of heat to materials not in contact with the tank sides. Properly mixing rail cars prior to discharge also greatly improve the yield.

How it works

While the rail tank car is being heated with steam through the tank car's heater coil system, the Pulsair mixer separately controls the sequential injection of compressed air or gas either directly into the rail tank cars bottom drain/outlet or through the bottom loading arm.

Why Pulsair?

  1. Helps reduce the heating time and energy needed to heat a railcar tank by over 50%.
  2. A Pulsair Tank Mixer or Electronic Tank Mixer can be incorporated into the bottom-loading arm.
  3. Increased heat transfer inside the tank avoids risk of burning or scalding the product.
  4. Tanks with heavy and settled slurries can be quickly mixed and agitated ensuring all the product is removed prior to returning the railcar.
  5. The Pulsair railcar tank mixing process is less expensive than heavy inefficient mechanical mixing contraptions that need to be lowered through the top hatch.

Benefits of Pulsair's rail car mixing systems:
