Three points of attention for the use of plate heat exchangers

Whether in industrial production or domestic water, plate heat exchangers can play a good role in heat exchange, high heat exchange efficiency and small heat loss, is an energy-saving and environmentally friendly equipment, but we must pay attention to this Three questions.
1. Pay attention to prevent the plate heat exchanger from freezing:
In winter, when the temperature is lower than zero degrees Celsius, the water inside and outside the heat exchanger will freeze, and the volume will increase after freezing, which will cause the problem of bursting. Therefore, the installation of plate heat exchangers must be equipped with drainage equipment, so that the equipment can drain the water when it is idle to prevent freezing.2. Dirt treatment in water:
Solid dirt: solids that are not melted in water, it is easy to block pipes and warm AC, and needs to be cleaned in time. It is recommended to install a filter to regularly protect and remove dirt.
Scale: Calcium and magnesium ions in water will form gutter scale under the action of high temperature, which will affect the heat exchange rate of the plate heat exchanger and reduce its performance.
Dirt disposal: In actual use, the dirt in the recirculating water will continue to decrease, so the heat exchanger does not need too much dirt treatment after a period of use.
3. Anti-corrosion:
Stainless steel has corrosion resistance to a large number of chemicals, but it is relatively insensitive to chloride ions. Therefore, the lightness must be restricted to 280ppm or more (below 55 ° C). And the PH value of water must adhere to a certain range.
Pay attention to these three issues in the use of plate heat exchangers, so that not only can ensure the stability of operation, but also can effectively extend its service life. YOJO brazed plate heat exchanger is the main product launched by YOJO. It is only made of 100% stainless steel without copper foil or nickel foil brazing treatment. The members of YOJO have accumulated rich experience in the field of heat transfer in the past 5 years, and have the most advanced technology of plate heat exchanger.
