The heat exchanger scale is serious, and processing method

You don't know what is the heat exchanger form, what material, if you know this, can be determined according to the scheme of heat exchanger type and scale formation.
If the scale is not large, long-term accumulation, you can find self cleaning or heat exchanger cleaning company cleaning.
If the recent scale particularly big, so to solve the problem of cleaning the scale, and then check the water problem, then the comprehensive solution is determined, if it is not up to the effect of heat transfer, the best for a not easy to scale heat exchanger, such as fluorine plastic heat exchanger.

Oh, OK, you know, thank you.
