Balloon gas


Simple, quick and safe - Balloon gas from Messer

Balloon gas utilisation

Whether it is for a wedding, a club celebration or a child’s birthday, as an advertising medium for a business launch, or for a publicity event, or a city festival..., balloons are not only popular among young and young at heart but they also attract impressive media attention. Balloons create a fanciful, lively and cheerful atmosphere boosting your event what you will treasure for a long time to come. And with our balloon gas you can be sure that your balloons really do take off. Balloon gas from Messer is easy and safe to use. Balloon gas is made up predominantly of helium. Helium is a colorless, inert gas, much lighter than air. Merely the pressure contained in the cylinders requires particular attention. Balloon gas is stored in cylinders under a pressure of 200 bar. At least the cylinder shoulder is brown. Messer offers balloon gas in the following cylinder sizes:

General advice

• With latex balloons, the gas escapes through the balloon walls within approximately 14 to 16 hours; therefore, latex balloons should only be filled immediately prior to the planned event. • The use of balloon gas in rooms is permitted; but make sure that there is adequate ventilation. • Do not inhale balloon gas directly. Although balloon gas is not toxic, it displaces vital oxygen from the lungs! • The use of hydrogen instead of balloon gas is prohibited on safety reasons!


Balloon gas - how much weight can a balloon carry ? 

The specific weight of helium in normal ambient conditions is about 0.18 kg/m3, that of air about 1.21 kg/m3. The difference between them means that there is a theoretical buoyancy of about 1 g per liter of helium. In case of helium balloons adequate buoyancy is guaranteed if the weight of the balloon and attachments (string, cards) is less than about 0.5 to 0.6 g per liter of balloon volume. The most commonly used measure to indicate the size of balloons is the diameters (d) in cm. The volume (V) in liters is then calculated as follows: V (liters) =(0.524/1000) x (d (in cm))³. Accordingly, a spherical balloon with a diameter of 30 cm has a volume of 14.1 liters and sufficient buoyancy for a weight of about 7 to 8.5 g. Pear-shaped balloons with an equal diameter have a slightly greater volume. For bigger balloons or air ships, the buoyancy has to be calculated individually.
