Ullage Floats

Ullage Floats

INDAC’s Ullage float is used to fill the void that occurs when wine is transported in a tanker; they push the fluid levels up creating less slack in the tank which stabilises the tanker, and lessens the chance of oxidation. Such a simple solution to a complex problem.


  • Our Ullage floats are 170 ltr
  • 12 kg units

"Ullage" comes from the Latin and French terms which boil down to the original meaning of the amount of liquid needed to fill a barrel up to the bung hole. By extension, it is now applied to the unfilled air space at the top of a bottle of wine, barrel or even tanker truck!
