Heat exchangers are generally used in a variety of different industrial processes. Basically, the main function of a heat exchanger is to transfer heat from one fluid to another. These exchangers are available in a variety of different designs and functions, and are generally made to order based on the specifications provided by the client. Welded heat exchangers are one of the most popular variants available in the market. If you are looking for an affordable heat exchanger that will last you for a long period of time, welded heat exchangers are the ideal choice. Here are some of the most important things that you should know about this type of exchanger.
How It Works
The functionality of this exchanger is very similar to an ordinary tubular exchanger. Welded plate heat exchangers, however, are generally much more efficient when compared to their tubular counterparts. The plates are welded together using a high-intensity laser, thus creating a plate pack. This plate pack is then mounted inside a standard cylindrical shell. However, apart from the fact that they are much more efficient, these exchangers also offer a number of other benefits.
Since there are no gaskets installed within these heat exchangers, you do not need to worry about any untimely blow-ups. This also means that the operation of the exchanger is relatively safe, with little to no risk of leakage. On top of that, this also allows the exchanger to work in very high temperatures. These exchangers can operate in temperatures up to 250 degrees Celsius. Apart from that, the working pressure is also much greater, as these exchangers can operate in conditions up to 25 bar. They offer higher K-values, have a relatively small liquid hold-up volume, and their space requirement is also relatively small, which means you can easily store them in various places. Perhaps the best reason why so many people prefer using these heat exchangers in different industries is because they are extremely easy to service. The ease of servicing them means that the exchangers will last for a much longer period of time, and you will not need to worry about taking each and every component apart for servicing.
Here are some of the main applications in which heat exchangers are generally used:
- Thermal oil heating
- District heating
- Evaporation for refrigerants
- Steam heating
- Condenser for refrigerants
Ordering the Exchanger
These heat exchangers are available in numerous different sizes. It is important that you choose the right size based on its application and your own requirements. Most companies that manufacture heat exchangers usually take custom orders. When you first contact the company, they will ask about your requirements and will give you a few suggestions about which type of exchanger is best for you. You can also visit the company’s office in order to inspect the various exchangers in person. This will give you a better idea of how they function and will allow you to see the salient features of each type of exchanger before placing an order.
