Market interest in CO2 transcritical systems has grown dramatically in the past four years as technology developments such as ejectors help to overcome their operational limitations in warm climates, according to Kenneth Bank Madsen, business development manager at Danish multinational Advansor.

“Interest in our transcritical CO2 racks has been huge,” Madsen told in an exclusive interview at Chillventa 2018, held in Nuremberg on 16-18 October.

“We can clearly see a development since the last Chillventa, in 2016,” he said.

All climates covered

Madsen was presenting Advansor’s CO2 transcritical systems for industrial and commercial applications. “We have a complete offering, from northern to southern Europe – we cover all climates,” he said.

Ejector technology helps in this regard. “The ejector gives us that extra energy efficiency we need to operate in warm climates,” said Madsen, presenting a rack designed for Portugal that is capable of operating in temperatures of up to 43°C.

For industrial, the largest capacity available on a single steel XL frame is 1.1 MW, he said.

Madsen also presented the firm’s compSUPER range of four different packaged refrigeration systems for supermarkets – the compSUPER XS ValuePack for convenience and express stores, the compSUPER rack for the supermarket and convenience sector, and the compSUPER SIGMA for integrating cooling and heating demands in one rack.

Advansor’s mini-booster, meanwhile, is proving extremely popular. Manufactured in the firm’s Polish factory, around 300 have been built this year.
