Cooling & Refrigeration
When being cooked, various kinds of food can very well just be thrown into one pot – but not in cold storage or during transport. Efforts toward greater energy efficiency as well as increasingly strict hygiene regulations demand discerning and individual planning of cooling and freezing engineering. With equipment of GEA, effective maintenance of the cooling chain is a matter of no great difficulty.

Our technicians and engineers are a well-versed team when it comes to storage and transport of the newest innovations from the frozen food sector. The trend to prepared and ready-to-eat products is reflected by appreciably greater refrigeration needs and, not least, by great changes in the appearances of supermarkets. It is especially the larger food retailers who are returning to their roots and are banning many non-food articles from their shelves. They increasingly offer their customer a larger selection of prepared, frozen food: for example pizza, french fries or fish sticks. This product group requires additional energy for logistics, stores, and presentation.
Food cooling and refrigeration represents a decades-old passion of GEA. A lot of supermarkets, retail shops, cold stores and logistics centers rely on GEA technology for normal cooling (medium temperature) and deep-freezing (low temperature) processes. In supermarkets for example, frozen food such as pizza, french fries and fish sticks have to be optimally-cooled in order to stay fresh.
The justified high hygiene and freshness standards in the European Union demanded for food mean that it is an absolute must to have reliable refrigeration of goods and an uninterrupted refrigeration chain. Constant and dependable refrigeration systems ensure that the right temperature will be maintained in cold storage rooms, cooling cabinets, freezer cabinets and freezer rooms.
Nowadays, sustainable food cooling and refrigeration is becoming more and more important. This is the reason why a lot of refrigeration systems are using the environmentally-friendly refrigerant R744 (CO2) for cooling and refrigeration processes. When used as a refrigerant in closed systems, the natural refrigerant R744 has no ozone depletion potential (ODP = 0) and a negligible direct effect on global warming (GWP = 1). It is a colorless gas which liquefies under pressure and has a slightly acidic smell and taste. R744 is not combustible, is chemically inactive and heavier than air. It has a narcotic and asphyxiating effect on humans only at higher concentrations. Carbon dioxide is available naturally in large quantities.
Moreover, an increasing number of GEA cooling and refrigeration systems are working according to the heat recovery principle, so that the energy received from refrigeration cabinets and rooms can be used efficiently – e.g. as heating or to supply hot water to supermarkets. This option will reduce the amount of gas or energy used for heating as well as the operating costs in the respective supermarket. Thanks to the concept of heat recovery, CO2 emissions to the environment are reduced significantly.
