Description
Brazed Plate Heat Exchanger (BPHE) consists of several corrugated plates with a brazing material between each plate. The space between two adjacent plates forms the channel in which the fluids flow. During the vacuum-brazing process the brazing material forms the joint at every contact point between the plates.
-
The BPHE should be mounted in an upright position.
-
Use flexible hoses or vibration dampers to reduce pulsation to protect the heat exchanger against vibration, thermal and hydraulic induced stress.
-
All items should be supported independently.
The BPHE should be installed as per below instruction:
Cleaning
While fouling on the BPHE, it is possible to remove most of the soft debris that is blocking the inside circuit by back flushing. Weak acids with concentration less than 5%; for example: citric, acid oxalic acid add in a tank. Circulate the cleaning solution. Before restarting the system, flush the plate heat exchanger with large amounts of fresh water to purge any remaining acid solution. If the acidity is too high, the copper and stainless steel inside the BPHE may be etched or corroded.
