Zero-impact cooling at the Famila supermarket

Gruppo Maxi Di Srl chose Arneg to develop the entire food refrigeration system and to equip its new store in the Vicenza Province, with Arneg refrigerated cabinets.
Maxi Di’s goal was to create an environmentally-sustainable system, using a zero-impact gas, while at the same time ensuring the highest efficiency on the market. Once the objective was defined and a tailor-made solution was designed for the customer, Arneg decided to involve CAREL in the project, looking to innovative modulating ejector technology to help meet these ambitious goals.

Regarding the CO₂ compressor rack, controlled by the pRack pR300T, three Carel EmJ modulating ejectors were used, for a total capacity of 185 kW. This solution brings energy savings during the summer of up to of 25%, when the outdoor temperature is higher, but also in winter, via the heat recovery system that provides heating inside the building. One essential feature of the ejector solution is continuous modulation that, through dedicated control algorithms, allows the system to continuously adapt to the variations in operating conditions that are typical of refrigeration systems. 

“For years, Arneg has been working effectively with CAREL, in a partnership based on mutual exchange. Research and technological innovation have allowed us over time to offer increasingly efficient and environmentally-friendly solutions, just like the one at the Famila supermarket in Lonigo”, commented Enrico Zambotto, Arneg’s Refrigeration Engineering Director. “As evidence of how much we are investing in this technology, we also now adopting ejectors in other installations, always using natural refrigerants, at numerous stores in Italy”.
