The Italian company designs, manufactures and installs commercial display cases using R290.
Hydrocarbons21 welcomes Italian OEM Arneg as a partner on the website.
Founded in 1963, the company, part of the Arneg Group, designs, manufactures and installs over 20 lines of plug-in R290 display cases for supermarkets.
“We are sure that HCs used in limited and safety quantities, are the best refrigerant currently existing,” Pierluigi Schiesaro, R&D Director of Arneg told hydrocarbons21.com. With this conviction, Arneg makes its whole range of plug-in units with the natural refrigerant, if the charge can be below the current limit of 150 g. It started using R290 in 2011, and has produced over 8,000 of these units.

Generally, the company observes a growth in small plug-in with R290. Arneg attributes this to the refrigerant being natural, cheap, efficient and having a very low global warming potential (GWP) of three. “Both in Europe and in the world, [R290’s] use is growing in small plug-in commercial refrigerating appliances,” said Schiesaro.

Arneg is in favour of increasing the charge limit for hydrocarbons, which is restricted by the IEC-335-2-89 standard. The Italian company argues that this will give more opportunities to develop new plug-in models and to reduce the number of compressors and circuits in existing ones. However, Arneg also argues that the risk of the higher charge may not be higher than that of current units with 150 g.
