Installation, use and maintenance of half volume heat exchanger
>>>
In order to prolong the service life of the heat exchanger, reduce the maintenance workload, save energy, and maintain efficient heat exchange, when the total hardness of the heated water is greater than or equal to 300mg/L (CaCO3), appropriate anti scaling measures should be taken to soften or stabilize the water quality, and the scale on the outer wall of the U-tube should be cleaned regularly.
Difference between positive displacement heat exchanger and semi positive displacement heat exchanger
>>>
The difference between the volumetric heat exchanger and the semi volumetric heat exchanger is that the semi volumetric heat exchanger tube bundle has a cylinder, while the volumetric heat exchanger does not.
How to clean corrugated tube volumetric heat exchanger
>>>
Add the configured descaling and cleaning agent into the circulating water of the cleaning tank in proportion for cleaning and descaling. Determine the cleaning cycle time and the amount of agent added according to the amount of scale in the corrugated tube positive displacement heat exchanger. After confirming that all the scales have been cleaned, move to the next cleaning procedure.
