Railcar & Tank Car Heating


Railcar heating or tank car heating is a necessary task for unloading or 

IMG_4773--.jpgtransloading railcars.This is a year round problem as many liquids need  to be heated to a specific temperature to be able to efficiently unload them such as oil, caustic soda, corn syrup, molasses, urea for DEF, etc. As the temperature gets colder a wider range of liquids and chemicals are affected and need to be heated in order to unload them.


The recommended method by railcar providers for this process is to use a low pressure steam generator. Sioux has been designing and building low pressure steam generators since 1939. Sioux units are rugged, compact, and easy to operate. Sioux offers many different mounting options along with the capability for customization
