The first plate heat exchangers appeared in the 6th century BC. e. From the 2nd to the 12th centuries, these devices were single-plate, but to reduce their size, it was decided to make the units multi-plate. Such devices are used to this day. However, they have been greatly improved. That is why they found their application in various industries and human activities, these devices are used where heat is exchanged from liquid to gaseous matter. However, before making a purchase, it is important to understand the technical specifications, which will be discussed below.
The plate heat exchanger "Ridan" is one of the most popular. It is able to work with various liquids, including aggressive ones. The gaskets of these devices are made of reliable and high-quality materials, which allowed to extend the life of the devices.
Technical characteristics of plate heat exchangers in terms of plate area and heat transfer
Ridan plate heat exchangers are offered for sale in a fairly wide range of sizes. For example, model № 04 has a plate area that is equal to 0.042 m 2 , while the heat exchange area in this case is 3.666 m 2 . The diameter is 32 mm. If we are talking about model NN No. 21, in this case the first parameter is 0.24 m 2 and the second is 56.16 m 2 , while the diameter is 100 mm. The plate heat exchanger "Ridan" is also offered for sale in the model № 65 / -10. In this case, the first of the above parameters is 0.68 m 2 , the second 472.6 m 2 , while the diameter reaches 200 mm.
The heat exchanger with one of the most impressive areas of the plate is HH No. 210. The first parameter is 2205 m 2 , the second parameter is 2037.42 m 2 , while the diameter is 400 mm. The plate heat exchanger "Ridan" is manufactured in a collapsible form. This production in Russia today is one of the largest. Before buying equipment, you need to study additionally, having considered the technical specifications. In general, they differ only in diameter and plate area, as well as heat transfer.
Additional technical characteristics of the plate model № 04
The Ridan Plate Heat Exchanger must be reviewed by you before purchasing. This will decide whether its characteristics are suitable for a particular system. For example, model №08 32, which is used for the exchange of gases or liquids in heat supply systems, has some distinctive features, among which are:
- stability in work;
- reliability;
- high build quality;
- durability;
- affordable cost.
The operating temperature range of this device varies from -30 to +200 . The gasket is based on the following materials:
- Nitrile.
- Silicone
- EPDM
- Viton.
As for the maximum working pressure, it should not seem above 25 bar. The permissible number of plates in the equipment varies from 5 to 90 pieces.
Additional advantages of the model
If you are interested in the plate heat exchanger "Ridan", then you should know that the plate acts as its main element. Due to this, the equipment has the ability to provide a highly efficient heat exchange to the heated gas or liquid from the coolant. The equipment described above is rather widely used in the conditions of large factories, small industrial enterprises and other organizations.
The main advantage of the heat exchanger is ease of use. Additional advantages include ease of installation and cost-effectiveness. It is important to highlight a rather high resistance to scale and deposits that can form from the coolant.
Technical characteristics and features of the heat exchanger brand NN № 42 150-10
The plate heat exchanger "Ridan" is offered for sale in a wide range. Among others, the model that was mentioned in the subtitle should be highlighted. It is equipment that can have a number of plates ranging from 11 to 686 pieces. The design uses tie rods, the number of which is 8.
The role of the distilled medium is water. A sufficiently important parameter for the calculation is power, in the case of the described model, this parameter is 4,000,000 kcal / h. The temperature of the medium at the outlet can be equal to 100 ° C, as for the heated medium, then its temperature can be equal to 85 ° C. At the entrance, the temperature of the medium can be equivalent to 160 ° C, as for the heated water, its temperature should be equal to 70 ° FROM.
The principle of operation of the plate heat exchanger brand "Ridan"
The plate heat exchanger "Ridan NN 04" works according to a certain principle, which consists in the transfer of heat from a hot heat carrier to a heated medium. Corrugated steel plates that are located in the frame and pulled together in a bag are involved in this process. The collapsible plate heat exchanger "Ridan" distills liquids that move towards each other, while a counterflow is provided.
In places where overflow is possible, there is a steel plate or rubber seal, it is this design feature that eliminates the mixing of liquids. All plates are the same, but each plate is rotated 180 ° relative to the other; therefore, when the packet is pulled together, channels are formed through which the fluid participating in the heat exchange flows. A similar arrangement of plates provides an alternation of cold and hot channels.
The plate heat exchanger "Ridan", the characteristics of which were presented above, has plates, the type of corrugation and the amount of which will depend on the operational requirements for the device.
Conclusion
A monoblock acts as a special type of plate heat exchanger; it is used in a two-stage hot water supply system. Such a plate heat exchanger "Ridan", the characteristics of which were mentioned above, has six ports, as well as two stages, which are enclosed in one case. If we compare such a device with individual heat exchangers, then the monoblock is less expensive and compact.
