Advantages of tubular heat exchanger
There are certain sectors where it is erroneously believed that the tubular heat exchanger has no place as they are dominated by other types of heat exchangers. However, tubular heat exchangers provide a number of special advantages that can make them an appealing option even though they usually involve a greater initial investment and they can result in a less compact solution than, for example, a plate heat exchanger. In this regard, it should be noted that the tubular heat exchanger hardly requires any maintenance tasks. In fact, there are customers who have not needed to disassemble our tubular heat exchangers for inspection and maintenance after several years of operation. However, plate exchangers, for instance, must be frequently refurbished and regasketed and, in addition, there is a high amount of joints, which results in considerable maintenance costs and non-productive time.
Tubular heat exchanger with customized design
On the other hand, due to the wide range of tubular heat exchanger configurations available in the industry, it is possible to make a customized design, which can perfectly suit the needs of each client. Thus, it is possible to consider, for example, modular designs in such a way that in the event of technical issues, the subsequent repair will involve a minimum cost, thus preventing the replacement of the entire heat exchanger. Also, in this way, if the problem does not affect many modules, the client will be able to continue with part of his production. This is why there is a growing number of customers that turn to SACOME to replace their existing lines of heat exchangers of other types with tubular heat exchangers.
Double tube heat exchanger for the cooling of beer must
An example of the above-mentioned is the recent manufacturing of a double tube heat exchanger for the cooling of beer must, a sector in which tubular heat exchangers are not the most common configuration. Focusing on the technical solution, although other types of tubular heat exchangers could also have been a convenient alternative, SACOME decided to follow the customer’s instructions and considered a Tube in Tube Sanitary Heat Exchanger (S-TF20-I) with corrugated inner tubes and shell, being completely modular. In addition, as the client was particularly concerned about the way of performing the maintenance tasks, SACOME decided to consider clamp-type connections on both sides (product as well as service side) to facilitate the disassembly and inspection of the equipment in the future.
In short, this is a good example of how the tubular heat exchanger can provide a number of advantages that, although it is not always initially foreseen, in the medium-long term it can help to achieve huge cost savings and to reduce maintenance times.
The importance of rheology in the design of any processing plant is crucial since the sizing of many of the elements composing it is very dependent on this “resistance”, also taking special relevance with food products: heat exchangers, pipes, valves, pumps, mixers, etc.
To design a heat exchanger it is necessary to have certain data, such as the process flow rate, the temperature and the physical properties of products.
Hairpin heat exchangers have a more efficient and economical design compared to a multiple pass heat exchanger when the process requires a temperature crossing between the cold and hot fluid.
