GEA keeps your process cool
Coolers belong to the technical equipment which has been successfully employed for a long time in many industries. In former applications, their main function was the heating of materials by utilizing the heat withdrawn from other materials to be cooled. The stove pipe of the good old iron stove is an example of a “classic cooler”. The hot flue gases are cooled in the stove pipe and the stove pipe in turn serves to heat the room. The principle applied today is often similar. On the one side, we have a fluid, such as flue gas which due to its composition is not suitable, or only with reservations, for further utilization, either because it contains aggressive components (SO2, NOx, etc.) or undesirable solids (soot, dust). On the other side we have a fluid to be upgraded by supplying heat. The application is different when the temperature of the off-gas is too high for further treatment or for a downstream process.
