Technical data

- 38 litres chamber
  
  XXL capacity – thanks to 38 litre chamber
  
  Large, larger, largest. Despite its compact outer dimensions, the new Lara XXL sterilizer is surprisingly large, with a chamber size of 38 litres.
- Wide variety of loading options
  
  Higher efficiency due to XXL capacity
  
  Lara XXL is able to reprocess up to 12 kg of containers and 10 kg of wrapped instruments, which is about twice the capacity of a standard sterilizer.
  Thanks to its chamber size and its 6-tray rack, it is
  extremely flexible.
- Compact outer dimensions
  
  Compact outer dimensions
  
  Due to its compact dimensions, Lara XXL is easy to install and without modification of the reprocessing room.
  A standard worktop with a depth of 60 cm is all you need to set up the XXL sterilizer.
- Eco Dry technology
  
  XXL performance thanks to Eco Dry
  
  The advanced patented Eco Dry technology adjusts the drying time to the mass of the load. This reduces the cycle time, increases the life span of the instruments and optimises the energy consumption.
- Best cycle times
  
  High capacity and best cycle times in its performance class
  
  With Lara XXL, large loads can be quickly and perfectly sterilized: 10 kg of wrapped or unwrapped loads, and 12 kg of containers.
  
  1: Wrapped 10 kg
  2: Unwrapped 10 kg
  3: Container 12 kg
- Time saving
  
  Lara XXL is able to automatically adjust the drying time for small loads (0.5 kg), average loads (3 kg) and full loads. Thus, a 3 kg load
  can be reprocessed in about 40 minutes using a type B cycle.
- Extends service life
  
  Automatic adjustment of the drying time depending on the load reduces the heat exposure time. This extends the service
  life of your instruments.
- Energy saving
  
  Optimising the drying time means less energy consumption. This makes Lara XXL the
  ”green solution“.
- Colour touch display
  
  XXL usability thanks to easy operation
  
  The Lara XXL colour touch display offers access to an intelligent menu structure with a wide range of options to make your daily work easier, faster, and more efficient.

- Easy water filling
  
  Easy manual filling or …
  
  An integrated high-capacity funnel prevents water splashes during the filling process.
  
  … automatic water filling
  
  An automatic water filling valve allows you to connect a demineralization system. Manual filling and draining are no longer necessary.
- Traceability
  
  XXL connectivity thanks to advanced technology
  
  The technical expertise makes the difference. The Lara XXL sterilizer is based on a sophisticated technical concept that offers future-oriented possibilities and significantly simplifies your workflow.
- Documentation
  
  Enhanced traceability
  
  The documentation is automatically saved via a high-capacity USB stick.
  
  The barcode label printer provides additional support on traceability thanks to the opportunity for linking cycle, sterilization package and patient.
