Controlled Atmosphere

Controlled Atmosphere technology

For a controlled atmosphere we provide a wide range of technologies such as ExtraFresh and Everfresh. The interior atmosphere is controlled to delay respiration and to extend shelf life for fruits and vegetables. Spoiling and moulds is minimized. We have the best solution ready for nearly each and every cargo.

Key benefits

  • Long-distance transport
  • Best conditions for time-sensitive cargo
  • Preserves product quality: freshness, colour and condition
  • The slow down of ripening and ethylene production

Commodities

Avocados: allows up to 35 days transit time
Bananas: allows up to 45 days transit time
Blueberries: allows up to 28 days transit time
Mango: allows up to 28 days transit time
Other commodities: upon request

 

Why Controlled Atmosphere reefer technology is recommended for sensitive fruits and vegetables

  • After harvesting, fruits and vegetables consume oxygen and release carbon dioxide & ethylene gas 
  • Release of moisture and heat generation provide specific challenges
  • Process of respiration results in deterioration of the product

Purpose of temperature and atmosphere control

  • Fruits and vegetables are still “alive” after harvesting
  • In a standard reefer container such products start to degrade and deteriorate immediately
  • Fruits and vegetables require an adjusted environment to preserve their condition
  • Atmosphere control slows down the ripening process and increases the shelf life of perishable products
  • At Hapag-Lloyd we assist with the following technologies: AFAM+, eAutofresh, Transfresh, Maxtend and PurFresh

The technologies represent the following specific advantages to prolong shelf life

  • Slow down of ripening process and reduce risk of decay
  • Decrease of dehydration (no weight loss)
  • Extension of market range from harvest to consumption
  • Maintenance of freshness, colour and condition to maintain product quality
  • Prevention / minimization of wastage and financial losses
  • Ocean transport to become a viable alternative to airfreight

 

A technology designed to control and preserve the desired transport atmosphere for fruitsand vegetables. Hapag-Lloyd ExtraFresh takes advantage of the natural fruit respiration process to slow down the ripening and thus maintain the cargo's quality and extend the product's shelf life.

  • Uses natural fruit respiration to slow down ripening.
  • Equipped with oxygen (O2) and carbon dioxide (CO2) sensors.
  • Equipped with membrane and vacuum pump to extract CO2 produced by the cargo.
  • Equipped with automatic ventilation to let in fresh air when O2 levels drop below set point.
  • Ethylene scrubbers are available for sensitive cargoes.
  • Typical products include avocados, bananas and mangos.

In addition to the technology available with ExtraFresh, the EverFresh technology allows injection of nitrogen and carbon dioxide before and during sea voyage. EverFresh technology is primarily used for low respiring cargo, that cannot produce the optimal atmosphere by natural respiration.

  • Equipped with oxygen (O2) and carbon dioxide (CO2) sensors.
  • Equipped with membrane and vacuum pump to extract CO2 produced by the cargo.
  • Equipped with automatic ventilation to let in fresh air, when O2 levels drop below setpoint.
  • Active Nitrogen (N2) and CO2 injection during transport.
  • As with ExtraFresh technology, EverFresh can also use natural fruit respiration process to slow down ripening.
  • Ethylene scrubbers are available for sensitive cargoes.
  • Especially beneficial for sensitive cargo with high CO2 requirements such as blueberries.

Liventus and Maxtend fitted containers describe a special supplement for reefer containers. They create a tailor-made atmosphere via pre-trip gas injections. An additional controller is monitoring & recording  the atmospheric composition inside the reefer. Such “Controlled Atmosphere” containers are ideal for low respiring cargo.

  • Pre-injection gas mixture (N2 and CO2) the system can modify and preserve desired atmosphere.
  • Equipped with oxygen (O2) and carbon dioxide (CO2) sensors.
  • Equipped with automatic ventilation to let in fresh air, when O2 levels drop below set point.
  • Ethylene scrubbers are available for sensitive cargoes.

Air Exchange Management is an automated ventilation system designed to regulate the oxygen and carbon dioxide level inside the container via the fresh air vents. This technology takes advantage of natural respiration processes of the fruit or vegetables and therefore does not require gas injections. Hapag-Lloyd operates one of the largest reefer fleets capable of Automated Ventilation.

  • Uses natural fruit respiration process to slow down ripening.
  • Equipped with carbon dioxide (CO2) sensors.
  • Equipped with automatic ventilation to let in fresh air, when CO2 levels reach set point.
  • Ethylene scrubbers are available for sensitive cargoes.
