A fruitful collaboration: Frascold, Cagnasso Frigoriferi and Cantine Capetta

Nature, technology and innovation: these are the principles that have always underpinned our continuous improvement of the entire production process which boasts impeccable quality control over the entire supply chain. So, each wine can express its own personality in its most authentic nuances”, says Paolo Bussi, Technical Director of Cantine Capetta. And he continues: “During each winemaking process, we pay utmost attention to temperature control to manage the refrigeration of the musts to the best of our possibilities. This is the most delicate phase that has a decisive influence on the organoleptic properties of the final product. For this reason, utilizing a high-performance refrigeration system plays a crucial role”. He adds: “In our case, following an increase in production, we were faced with the need to double the cooling capacity for the refrigeration of the musts, that is about 20,000 litres/hour from 28 °C to 0 °C. Installing an additional ammonia-based chiller on top of the existing one would have required a specific license and more stringent controls, as well as higher water consumption for the cooling tower. This was definitely not an option for our company that, besides being the first one in the sector, in Piedmont, to have obtained the ISO 14001 certification, has always been devoted to sustainability and the protection of resources”. He concludes: “So, we relied on the consolidated experience of Cagnasso Frigoriferi, that directed us towards a propane chiller which offers numerous advantages such as proven efficiency, simplification of system management and reduction of the carbon footprint”.

More specifically, the project consisted in the construction of an advanced R290 chiller, capable of ensuring a cooling capacity of 581kW at 50Hz, obtained thanks to two Frascold semi-hermetic screw compressors. A compact system, with a glycol-saving plate heat exchanger and a Microchannel air-cooled condenser with high efficiency and low refrigerant requirements. The chiller also stands out for its efficiency management software, regenerative heat exchanger, economisers, EC fans and a full stainless steel body. In addition, to ensure maximum safety, Frascold has equipped the compressors with flow switches and we have included a sniffer to disperse any leaks of refrigerant into the air, making it inert thanks to the electricity supply cut and the activation of the fans”.
