Generally speaking, the cleaning of plate heat exchanger shall be based on the scaling conditions. When the heat exchange effect cannot meet the process design requirements, it must be cleaned.From the point of view of energy saving and consumption reduction, if 0.2-2 mm scale is adhered to the heat transfer surface of plate heat exchanger, the heat transfer efficiency will be reduced by 10-40%, 0.3 mm silicon scale, and the heat transfer efficiency of the heat exchanger will be reduced by 90%. Prepler thermal equipment reminds you of the importance of timely cleaning of plate heat exchanger.Proper use of plate heat exchanger:

1. At the beginning of operation, if the pressure of the two media is different, slowly open the valve at the low pressure side, and then open the valve at the high pressure side.

2. During shutdown operation, the fluid on the high-pressure side shall be cut off slowly, and then the low-pressure fluid shall be cut off. Please note that this will greatly contribute to the service life of the equipment.

3. The equipment shall be operated under the specified operating temperature and pressure range of the product. Overtemperature and overpressure may damage the sealing performance and cause leakage. It is forbidden to impact violently during operation.
