The refrigeration sector is by far one of the fastest growing sectors in the world. In countries characterized by strong demographic growth and an increase in purchasing power, more ready-to-eat or frozen packaged foods are required. To meet demand by ensuring the cold chain, producers, transporters and outlets will increasingly use chillers and freezers. At the same time, in Europe and North America, there is a vast market for replacing installed devices with more efficient solutions (the energy used for refrigeration is among the largest expenditure items) and more environmentally friendly, discarding HFC and HCHC in favor of natural refrigerants such as CO2 and ammonia.
