The Ultimate Gas Flush System


The PerfoTec O2Control is the ultimate gas flush system for vertical, horizontal and flow packing machines. It combines food grade compressed air, carbon dioxide and nitrogen to reach the desired gas mix. Fresh produce packers reach the required level of modified atmosphere in the packs from the moment they are packed, while reducing gas waste, increasing packing speed, reducing product in seal and achieving an accurate and stable O2 and CO2 levels with a deviation of less than 0.5% between packs. PerfoTec’s patented gas flush system with intelligent gas mix/flow software has three oxygen sensors which ensure pre-gas flushing takes place in the tube until the desired gas mixture is reached. After that the packaging starts with exact and consistent O2 and CO2 concentrations.

Real time production and sensor data is recorded and displayed on the PerfoTec O2Control panel. The settings are adjusted automatically to ensure a maximum deviation of 0.5% in O2 levels.

PerfoTecO2Control - gas flush systemSecurity checks are built into the system whereby the packing machine is stopped if the O2 levels are too high or too low, and additionally, even if the packing machine has to stop frequently due to product shortage, the O2 and CO2 levels still remain stable. When the packing machine is turned off, the gas flow will automatically be shut down. The result is a significant reduction in gas waste and reduced costs. Food grade compressed air combined with a carbon filter replaces expensive and less safe O2 gas cylinders, leading to reduced costs and improved production safety. The high flow and low-pressure gas flush reduces the turbulence and velocity of the gas going into the packs, resulting in a significant reduction of product-in-seal and a higher packing speed. This leads to higher productivity and reduced overall costs. Production data, sensor data, and operator actions are recorded while the PerfoTec gas flush system is in production mode. This data is summarized in a report and accessible online. The reports can be downloaded for later analysis and local storage.

Gas flow software panel

  • Pre-gas flushing until the right level is reached.
  • Then packaging can start, so your first package already has the correct O2 and CO2 level
  • Real-time data display of three oxygen sensors
  • Packs are filled with exact O2 and CO2 concentrations
  • PerfoTec O2Control Gas flush System automatically adjusts O2 and CO2 levels
  • Security check on all three gas flows and O2 level, if O2 level is too high or too low packing machine stops
  • No gas flow when packaging machine is off
  • Even if the machine has to stop frequently due to productshortage, the O2 and CO2 levels remain stable
  • Online data storage of production and sensor data


To ensure uniformity of the gas in the tube during production, the O2Control Gas flush System is equipped with 3 sensors:

  • Sensor 1: Measures the input O2 level
  • Sensor 2: Measures the O2 level near the sealing jaws
  • Sensor 3: Measures the O2 level near the top of the filling tube

Mounting bracket

PerfoTec will manufacture and supply a custom-built mounting bracket, to integrate the PerfoTec O2Control display on your packaging machine or on the wall of your factory.

Gas lance construction

  • PerfoTecO2Control flush system - Gas LanceAccurate and precise gas flushing
  • Sensor in filling tube measures in-bag O2 and CO2 concentration
  • Gas flow is controlled not to exceed max level of 0.5% O2 deviation between packs
  • Uses food grade compressed air combined with a carbonfilter. This is an advantage in comparison to the use andstorage of expensive O2 gas cylinders
  • Reduction of product-in-seal
  • High flow/low pressure gas flush for less turbulence and higher packing speed
  • Significant gas savings
