2019/05Plate cleaning and protection
Keeping the sheets clean is one of the important conditions for maintaining a high heat transfer coefficient. Between the plates, the medium moves along the narrow and meandering flow path. Even if a relatively thick scale laye...+ More

2019/05What are the characteristics of brazed plate heat exchangers
(1) small and efficient: because the heat transfer process is carried out in a 0.5mm thin plate, it has a high heat transfer efficiency, the heat transfer efficiency after the couplet is more than 90%. (2) Dust is difficult t...+ More

2019/05Analysis of common faults in the operation of brazed plate heat exchanger
1. Seepage leakage of plate heat exchanger Because the plate heat exchanger has a long sealing perimeter and a thinner plate, it may show a leaking appearance during the application process. Leakage appearance can be divided ...+ More

2019/05Brazed plate heat exchanger process requirements
1) pickling temperature: increasing the pickling temperature is conducive to improve the descaling effect, if the temperature is too high, it will aggravate the corrosion of the acid washing plate on the heat exchanger plate, t...+ More
