The Twin II semi automatic keg cleaner and filler is designed and manufactured by Malek Brautech GmbH, who specialise in the field of keg filling and keg cleaning systems. The Twin II is a cost-effective 30 keg/hr semi-automatic machine for cleaning and filling kegs, with a roller support platform on the filling station and a keg slider to facilitate operation. It is equipped with patented filling control by temperature measuring, which is ideal for different fill volumes, and is suitable for cleaning using alkaline and/or acidic detergents.

  • 30 keg/hr output at 50 L
  • Fully automated patented cleaning & filling processes (see Downloads)
  • User-friendly operation
  • Single cleaning station with cleaning program for 3 keg sizes
  • Single filling station
  • Integrated adjustable centring unit for kegs of different diameter
  • Treatment heads are the same as those on Malek's automatic machines, to enable high liquid flow rates
  • Pneumatic stainless steel seat valves with position indication (open/closed) for safe operation as well as early recognition of leakages
  • Stainless steel dispensing heads
  • Detergent comes from an integrated, steam heated tank
  • Test valve in the feed pipe to check the concentration of detergent in the detergent tank
  • CIP program with 6 selections
  • Siemens S7 operator panel with backlight
  • Equipped for one fitting type
  • Many options available including: additional cleaning station & detergent tank for cleaning with 2 detergents (i.e., caustic & acid); dosing unit, change parts for KeyKegs, etc (see Specification)

Please call us on 01404 892100 to discuss your kegging requirements.

  • Suitable for both alkaline and/or acidic detergents
  • Change parts for KeyKegs are available as an optional extra


A keg is placed on each station by the operator, and the integrated arrestor ensures that they are positioned correctly. The machine is started by dual push-bottom operation. Kegs are cleaned on the first station, and pressurised and filled on the second. For intensive cleaning of the basket, the detergent is flushed through the CO2 valve via counter flow method. The complete cleaning cycle is done with fresh water, caustic or acid from the integrated machine tank, and hot water, before the sterilising process takes place. A pulsed rinse ensures that the spear and the inner surface of the keg is completely cleaned.
During cleaning and filling cycle, the operator is free to carry out other duties.

The operator slides the filled keg onto the waiting platform, transfers the cleaned keg to the filling station, and places the next keg to be cleaned on the cleaning station. On commencement of the next cycle, the operator slides the filled keg down the slider.

The case studies below are only two of many of our kegging installations. Please call us on 01404 892100 to ask about the rest!
