Refrigeration has emerged as a strategic pillar for sustainable development in Africa, influencing food security, public health, energy efficiency, and job creation. This priority was strongly underscored at the first International Conference on the Popularization of Refrigeration in Africa (CIVUFA), held on November 12, 2025, in Ouagadougou. Gathering nearly 300 participants from 23 countries, the event outlined a unified continental vision for strengthening the refrigeration and air conditioning sector through institutional support, technology transfer, and capacity building. The ref

Partner's material NOVA FRIGO introduces a new CO2 chiller with heat pump, created as part of the project promoted by the Lombardy Region “Ricerca & Innova” call for proposals, made possible also thanks to the technological contribution of Frascold, relating to an innovative heat pump with natural CO2 refrigerant and without the use of fossil fuels. This is a novel solution in the Italian context, combining high performance, reduced environmental impact and application versatility. The use of CO2 as a natural fluid and the adoption of high-pe

By Kushal Aurangabadkar In industrial ammonia refrigeration systems, pumps play a vital role in circulating liquid ammonia to maintain cooling efficiency across evaporators and heat exchangers. The choice of pump type directly impacts system reliability, safety, and maintenance requirements. Among the most common options are conventional (mechanical seal) pumps and sealed (hermetic) pumps. Understanding their differences helps refrigeration professionals select the right technology for their facility. These pumps, often installed in parallel for redundancy, are the backbone of i
