We utilize a replaceable inner bag system in for stainless steel kegs. We are focused on improving this inner bag technology, making it stronger and more effective for steel keg applications. The kegs are currently offered with a type S fitting, and are available in 20L slimline and 30L eurokeg formats. Type A fittings are also under development. Importantly, as the bag producer, we offer custom inner bag solutions for any type of keg, tailored to your specific needs.
