In order for an industry to function correctly, many things must be thought of, above all to have a good temperature despite the large size of the building and to have machinery work correctly, constantly and without sudden blocks. In some industries it is essential to install industrial heat exchangers, devices that allow for an exchange of thermal energy between two fluids of different Industriell ventilation Malmö. These devices are used in large industries where there is a need to maintain a fixed temperature in some areas or to change the state of a fluid, for example making it go from liquid to gaseous.
Depending on the type of industry, the right model must be chosen to ensure maximum efficiency in the processes. The factors of choice can be: the material with which the appliance is built, the ease of use, the seal (in case of working with toxic fluids), the maintenance costs (which can also be very high), the reliability and safety. But how exactly do heat exchangers work and what are the most common models you can find in the market?
What is a heat exchanger
Not all industries need a heat exchanger, but only those that have to carry out specific production processes, such as: pasteurization, sterilization, a change of state such as crystallization, evaporation or condensation, or cooling or heating of fluid currents. From this it can be deduced that these appliances are indispensable in the food or chemical and petrochemical industries, where the production environments must have a high level of safety. The most common industrial heat exchangers are those with plates, shell and tube or finned coils.
The choice varies from the type of production to be performed, the size of the industrial plant and the safety standards to be respected. A major distinction that must be made is between water/air exchangers and air/air exchangers, because they have differences in price, functioning and methods of use.
The water/air exchangers for industrial use are able to cool/heat an environment in a very short time. They are chosen in very large buildings instead of air conditioners because they offer great savings in terms of energy and money. Usually, industries choose these heat exchangers if the air inside the plants is oily or full of dust, since they prevent humidity from entering the electrical panel. A water/air exchanger can only be installed if the temperature outside the system is higher than the inside.
The air/air exchangers for industrial use are usually installed when the external temperature of the system is lower than the internal one. These appliances are perfect for systems or very small rooms, since they have a lower cooling capacity than water/air exchangers, however they also require less maintenance.
