DENMARK: Maersk Container Industry (MCI) is to supply 8,600 Star Cool Integrated lower GWP reefers to Hamburg-based global container line Hapag-Lloyd.

All 8,600 reefers are ready to switch over to R513A, the lower GWP alternative to R134a. 2,000 will be controlled atmosphere reefers.

This latest contract from Hapag-Lloyd follows an order for 1,000 Star Cool units using R513A placed last year. MCI has already commenced production of the 8,600 Star Cool Integrated reefers at its facility in Qingdao, China.

“It is reassuring to know that we have the ability to fully convert a large part of our reefer fleet to a lower GWP refrigerant solution, without having to make any modifications to the machines or compromise on performance,” commented Niklas Ohling, senior director at Hapag-Lloyd.

According to MCI, all Star Cool units produced since July 2017 provide operators with the option to charge with R513A or R134a, without restriction. Units produced prior to that date can also be adapted to run on R513A with minor modifications.

R513A is a binary mixture of R134a (44%) and R1234yf (56%). It has a GWP of around 630 and carries the ASHRAE safety classification of A1.

The 8,600 Star Cool order is part of an investment in a total of 11,100 containers announced by Hapag-Lloyd in August. The new containers will be integrated to the company’s existing fleet of 91,000 reefer containers.
