The contact point of each plate of the brazed heat exchanger is also the welding point, so as to bear the pressure of the medium. Brazed plate heat exchanger is an evolution of the detachable heat exchanger. Fluid flows through channels between plates through carefully arranged corner interfaces. Refrigerant and heat medium always flow in opposite directions in adjacent channels for heat transfer.The sealing material is changed from copper or nickel. All the plates are bonded together by copper or nickel solder.
Pocedure of Maitence for cleaning
With hot water dissolve TNNB safe efficient cleaner, using circulating pump from the bottom of the water injection, From the top outlet back (secondary water), cycle cleaning until testing qualified.
Because TNNB scale remover only reacts with scale and does not react with metal and other substances, nor does it corrode, the Ph value is constantly detected during the cycle cleaning, and the scale sample is used to test the cycle cleaning solution.
If the scale sample has a reaction, it means that the water has a drug effect, while there is no reaction in the system (no gas escape), it means that the scale in the board has been cleaned, otherwise, there is still 1% scale in the system, as long as the water has a drug effect, it will continue to react.
