Plate heat exchangerdue to its many advantages, is widely applied to various industries, but at the same time, there’re many problems in process of using, including gasket swelling, which is a problem many users and even heat exchanger manufacturers that met, so what’s that all about?Today let us tell you why.

As we all know, plate heat exchanger gasket looks like a small one, and he weight is also very light, but it’s role in PHE is essential - heat exchanger sealing. Small gasket plays a key role, so why swelling happens?

1, The reason of the medium. The medium of different temperature, different concentrations and different physical property must use different material gasket , such as heat conduction oil must use oil resistant NBR rubber gasket , water use EPDM gasket can be completely, if the heat conduction oil to use EPDM gasket , then gasket swelling that is inevitable happen, so must according to the different properties of medium to choose the appropriate gasket  material.

2, Raw materials. As everybody knows, gasket production began at the process of rubber mixing, rubber mixing elements also have a lot of kinds, content is also different, different raw materials and chemical reaction occurs between different medium, the generation of this kind of chemical reaction will cause deformation of gasket , so how to use the appropriate gasket , this test to the manufacturers of raw materials and chemical reactions occur between different media.

Once swelling occurs, the gasket will lose its original elasticity, aging, and the gasket  will lose its sealing function, the heat exchanger will inevitably leak.

Our technicians with senior industry experience, our standard production process and quality control system and the world famous Gislaved Gummi production manufacturer is consistent, can be very clear to tell you what kind of gasket plate heat exchanger is the most suitable working condition, you if you have demand of the heat exchanger, you are welcome to come to consult.
