Link Logistics adopts CO2 for Hobart Airport cold storage facility

Tasmania-based freight specialist Link Logistics has chosen natural refrigerant CO2 for its new cold storage facility at Hobart Airport. Accelerate Australia & NZ reports.

The firm, which also has facilities on the Australian mainland in Melbourne and Sydney as well as in Shanghai, China, manages every aspect of door-to-door distribution, helping to protect the quality and shelf life of perishable products.

In October 2018, Link Logistics signed on as the first tenant of a new freight handling facility and commercial precinct at Hobart Airport. The new facilities allow local producers to transport their fresh produce – such as seafood, meat and fruit – by airfreight directly to their export destinations.

Previously, Tasmanian producers of goods for export had to transport their freight to the northwest coast by truck, where it was loaded onto ships bound for Melbourne or Sydney.

“Link Logistics invested more than AU$3 million in the new freight forwarding and cold store facility,” says Chris Fox, the firm’s Tasmania director.

Degree C, the contractor on the project, works in the industrial, commercial and residential sectors. “Although Tasmania is small, it is big in renewable energy. This clean, green image was one of the key drivers to install a refrigeration system with a clean, green, future-proof refrigerant,” said Pieter Boon, project manager (refrigeration) at Degree C.

“The cool Tasmanian climate also makes transcritical CO2 particularly suitable for this state,” Boon adds.

Compelling business case

Advansor, a Danish multinational CO2 system manufacturer represented by the Natural Refrigerants Company in Australia, provided the rack.

“Degree C did all the groundwork to promote CO2 as the appropriate solution for the project,” says Jonathan Hare, refrigeration engineer at the Natural Refrigerants Company.

The CO2 transcritical system was commissioned on 19 November. “It is the only one in Tasmania with 1,000 m2 of freezer and 735 m2 of chiller space,” said Link Logistics’ Fox.

The CO2 transcritical system has 78 kW of cooling capacity on the medium-temperature side and 120 kW on the low-temperature side. It has an air-cooled gas cooler and desuperheater. Gu╠łntner provided the gas cooler, desuperheater and evaporators.

“Pieter and I worked through several iterations of the overall layout, design and capacity requirements,” Hare explains. “All options were costed to find the best solution for the end user.”

Hare is convinced that the business case for adopting CO2 for this particular installation is compelling. “The environmental benefits in terms of direct emissions are clear,” he says.

It is still too early to draw conclusions about energy performance. But Hare is confident that the CO2 system will deliver. “Once the system has been running for a while, I believe it will speak for itself in terms of energy efficiency,” he says.
