Volume reduction

Reactivate unused assets

Do you have unused 50l kegs in your keg fleet, but have for example an increasing demand for 30l kegs? No problem! Our network provides you with competent experts who can downsize your used 50l kegs to 30l. Our innovative technology is now available for volume reduction of EURO and DIN kegs.

The following types of kegs can be used for volume reduction: 

Initial size
Realizable size
EURO 50l:EURO 30l, EURO 25l,
DIN 50l:DIN 30l, DIN 20l, DIN 15l

Achieve a unified market identity

You can replace the top chime and get a new one with embossed lettering according to your specification. As an alternative we can knurl out the existing embossing and apply your logo or brand name on the keg body. This way you do not only have a proof of ownership but also a standardized brand appearance.
