DOT vs. ASME: Why It Matters
The key difference between a DOT propane tank and an ASME propane tank is transportability. DOT tanks are built and tested to Department of Transportation standards for safe transport of hazardous materials on public roads. An ASME tank, by contrast, is designed for permanent installation only. If your application involves moving the tank — between properties, to events, across a farm, or on job sites — a DOT tank is what you need.
Versatile Applications
This 120 gallon DOT propane tank is popular for construction site heating, event and tent heating, seasonal property use (hunting cabins, seasonal businesses), mobile food service, farm propane tank applications where the tank moves between fields, and any scenario where propane needs to be portable.
Stationary Use Too
While DOT certification is about portability, nothing stops you from using this tank as a permanent above ground propane tank. Many buyers purchase DOT tanks for the flexibility — install it now, move it later if your situation changes. That flexibility has real value.
