Balloon Propane Tanks


Balloon Flying MenuPostflight Procedures > Propane Management and Fueling > Balloon Propane Tanks

Propane tanks used in hot air balloons are mainly constructed of either aluminum or stainless steel. Most aluminum tanks are vertical 10-gallon cylinders (DOT 4E240), built primarily for forklift trucks. Stainless steel tanks are either vertical or horizontal, of many different sizes, and built especially for hot air balloons. [Figure 5-1]

FIGURE 5-1.—Propane tank.

All balloon cylinders have liquid service valves, excess-pressure relief valves, and liquid level indicator valves. Many tanks have vapor service for pilot lights and some have an emergency valve or filler valve. Some tanks may have as many as five individual service valves, and some have only one combination (3-in-1) valve. There is no standard 5-5 valve configuration for balloons. Generally, the large valve handle is liquid and the smaller handle is vapor; tanks and/or handles are usually labeled.
