GERMANY: Retailer Netto Marken-Discount has reported a successful start to its three-year trial of Carrier Transicold’s CO2 refrigerant trailer prototype.

The prototype is one of the first refrigeration units to use CO2 in a closed-loop system. It uses technology from Carrier Transicold’s NaturaLine container refrigeration system, assembled inside a traditional Vector unit chassis and powered by the same E-Drive all-electric technology as the existing Vector range.

The trial with Netto, announced in August, was the first such trial on mainland Europe. UK supermarket Sainsbury’s started trials with three of the units last April.

“Our test with the Carrier CO2 trailer prototype unit has started successfully,” said Christina Stylianou, head of corporate communication, Netto Marken-Discount.  “Our drivers confirm that operating this unit is quite similar to conventional refrigeration units. We are eagerly waiting for the high and busy season during which we will continue to monitor the unit’s efficiency levels.”

The CO2 trailer unit prototype is in use Mondays through Fridays in a two-shift operation, distributing goods from a central warehouse in Ponholz, near Nuremberg, to Netto subsidiaries in the area.

“By testing the prototype, Netto is taking a step closer to achieving its own ambitious environmental goals,” Stylianou added.

“Our ultimate vision is to see temperature-controlled units running on natural refrigerant in mainstream production.Today, with the support of Netto, we are one step closer,” said Carrier Transicold & Refrigeration Systems president David Appel.
