The size is short and the inch is long. Even if the application is convenient and wide, such as plate heat exchanger, there are some small problems that have to be said. It is suitable for most working conditions but there are some unsuitable working conditions. Your working condition will belong to that
A small part of the scene?
Are there any disadvantages to detachable plate heat exchangers?
Come and have a look!


Since it is not a closed container and the presence of heat exchange element rubber strips, the pressure bearing capacity and temperature resistance capacity of the detachable plate heat exchanger are slots:


Just like the barrel effect, the maximum pressure of a plate heat exchanger is determined by the pressure capacity of the weakest component-the gasket.


The pressure-bearing capacity of the rubber strips is advertised as 2.5MPA (25bar), but there are still differences between manufacturers; but they belong to the same category of plate heat exchangers. Plate and shell heat exchangers without rubber strips can be pressurized.
Reach 10MPA (100 bar).
In the same way, the temperature resistance of the rubber strip is also one of the shortcomings. The highest temperature resistance of fluorine rubber (FKM) is only about 200°C, so working conditions such as high temperature heat transfer oil are not suitable for removable
Type plate heat exchanger.


For the wide-channel plate heat exchanger, even if the groove is deep and the normal corrugation pitch is large, the runner will not be as wide as the tube heat exchanger. If it involves large-scale food projects, the entire system, in order to prevent frequent
If it is blocked, it may be necessary to install an additional filter system or a regenerative cooling system to prevent supersaturation and precipitation of particles.

But for media containing large particles, it is not completely impossible to use wide-channel plate heat exchangers. The high fouling rate and low heat transfer efficiency of shell and tube heat exchangers cannot be compared with the low fouling rate and heat transfer coefficient of plate heat exchangers.
High performance is the same.


After all, the working conditions are only similar, but not exactly the same. If you want to try new equipment, the most reliable way is to consult a professional engineer. RPT welcomes customers to call us!
