Low-carbon cooling units improving sustainability
Hapag-Lloyd has invested in low-carbon cooling units featuring the R513A refrigerant system to maintain and expand its container fleet.
The global container line has purchased 3,700 Star Cool Integrated containers from Maersk Container Industry (MCI), of which 1,000 will be chilled by R513A with a Global Warming Potential (GWP) of less than 56% of the commonly used R134A refrigerant.
Niklas Ohling, senior director at Hapag-Lloyd, said: “Reducing carbon emissions is a key objective on our sustainability agenda and we believe in the potential of environmentally friendly refrigerants as an important element in achieving this.
“At the same time, we have ensured in earlier field trials with MCI that the cargo quality and energy efficiency remains unaffected by the new refrigerant.”
First R513A carrier
Hapag-Lloyd, which has a fleet with a total capacity of 1.6m teu servicing more than 600 ports, is the first carrier to widely deploy the R513A system.
R513A addresses the environmental protection legislation for existing technology platforms introduced with, for example, the F-gas regulations in the EU.
To meet the increased demand in reefer transport, Hapag-Lloyd decided to use Controlled Atmosphere (CA) technology for its containers to expand its ExtraFresh and ExtraFresh Plus services.
The CA technology slows the ripening of fruits and vegetables, allowing them to be transported over longer periods and reach their destination in optimal condition without over-ripening or decaying.
The containers are being produced at and delivered from MCI’s manufacturing facilities in China and Chile.
