MAP Mix Focus

Mid-capacity gas mixer for MAP packaging lines

  • Medium-capacity mixing of 2 or 3 gases
  • Stabile gas flow and accurate gas mix every time
  • Warns when supply gases running low
  • Minimize risk of operator error


The Dansensor® MAP Mix Focus uses an electronic mixing principle to accurately and reliably mix either 2 or 3 food-grade MAP gases. Monitor the gas mixing process in real time with a coherent on-screen overview that includes precise information about the current gas flow, total gas consumption, and actual MAP gas mix.

Don’t waste time and risk errors manually setting up and adjusting your mixer every time you begin packaging a new product. With the Dansensor MAP Mix Focus, specific gas mixes and corresponding alarm levels can be easily entered on the intuitive touchscreen. Three configurations can be saved on the instrument to avoid errors when adjusting the gas mix for different products.

The Dansensor MAP Mix Focus also offers flexibility regarding gas supply and gas mix settings. You no longer need to worry about unstable inlet and outlet pressure levels. Each gas line is fitted with a pressure sensor and an early warning alarm can be programmed to warn (visually and audibly) when supply gases are running low. The mixer easily works with both gas generators and bottled gas that deliver different or varying inlet pressures. It delivers a stabile gas flow and accurate gas mix every time.

The Dansensor MAP Mix Focus features a mid-capacity flow rate, suitable for both flow packaging machines with both direct gas feed, as well as tray sealer and thermoform packaging lines with buffer tanks.
