Plate heat exchanger "Ridan": technical specifications

The first plate heat exchangers appeared in the 6th century BC. E. From 2 to 12 century, these devices were single-plate, but to reduce their size it was decided to make aggregates multi-plate. Such devices are used to this day. However, they have been significantly improved. That is why they found their application in various industries and human activities, these devices are used where the heat exchange occurs from liquid to gaseous substance. However, before making a purchase it is important to understand the technical characteristics, which will be discussed below.

The plate heat exchanger "Ridan" is one of the most popular. It is able to work with a variety of fluids, including aggressive ones. 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

The plate heat exchangers of "Ridan" brand are presented for sale in a rather wide range of standard sizes. For example, model HH No. 04 has a plate area of 0.042 m ² , while the heat exchange area in this case is 3.696 m ² . The diameter is 32 mm. If we are talking about the HH model 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 offered for sale also in the model HH No. 65 O / S-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 demountable form. This production in Russia today is one of the largest. Before buying the equipment you need to study in addition, considering the technical specifications. In general, they differ only in the diameter and area of the plate, as well as heat transfer.

Additional technical characteristics of the plate model NN № 04

The plate heat exchanger "Ridan" should be considered by you before purchase. This will allow to decide whether its characteristics fit a certain system. For example, model НН №08 DN 32, which is used for the exchange of gases or liquids in heat supply systems, has some distinctive features, among them:

• Stability in work;
• reliability;
• High build quality;
• durability;
• Affordable cost.

The operating temperature range of this device varies from -30 to +200 ^о С. The following materials are based on the gasket:

• Nitrile.
• Silicone.
• EPDM.
• Viton.

As for the maximum operating pressure, it should not appear 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 serves 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 production enterprises and other organizations.

The main advantage of the heat exchanger is its ease of operation. Additional advantages can be considered simple installation and economy. It is important to allocate a rather high resistance to scale and deposits, which can form from the coolant.

Specifications and features of the heat exchanger brand NN No. 42 DN 150-10

The plate heat exchanger "Ridan" is offered for sale in a wide range. Among others, it is worth highlighting the model that was mentioned in the subheading. It is an 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 100 ° C, as for the heated medium, its temperature can be 85 ° C. At the inlet, the temperature of the medium can be equivalent to 160 ° C, as for the heated water, its temperature should be 70 ° C FROM.

The principle of operation of the plate heat exchanger brand "Ridan"

The plate heat exchanger "Ridan NN 04" operates according to a certain principle, which consists in transferring heat from the hot coolant to the heated medium. In this process corrugated steel plates are involved, located in the frame and tied together in a bag. The demountable plate heat exchanger "Ridan" surpasses the fluids, which move towards each other, while the countercurrent is provided.

In places where there is a possibility of overflow, there is a steel plate or rubber seal, it is this design feature that excludes the mixing of liquids. All plates are identical, but each is deployed in relation to the other at 180 ° C, so when the package is pulled together, channels are formed through which the liquid participating in the heat exchange flows. A similar arrangement of plates provides alternation of cold and hot channels.

The plate heat exchanger "Ridan", the characteristics of which were presented above, has plates, the shape of the corrugation and the number of which will depend on the operational requirements for the device.

Conclusion

A special kind of plate heat exchanger is a monoblock, it is used in conditions of 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 housing. If you compare this device with individual heat exchangers, then the candy bar is less expensive and compact.
