3 major hazards of plate heat exchanger without cleaning

Because of long-term use, the plate heat exchanger will produce certain scale in the case of long-term heat exchange. If it is not cleaned, the heat exchange efficiency of the heat exchanger will be reduced. YOJO is committed to the production of heat exchange equipment For many years, what are the hazards of not cleaning the plate heat exchanger?

1. The scale plug for a long time leads to the deterioration of the heat exchange working conditions. The heat transfer surface of the heat exchanger exceeds the rated temperature or is locally overheated, which may cause cracks and cracks in the heat exchanger, causing accidents. The accumulation of fouling threatens the safe operation of the heat exchanger, and shortens the service life of the heat exchanger, so that the heat exchanger faces equipment shutdown and maintenance, and a new heat exchanger needs to be replaced in serious cases.
2. During the use of the plate heat exchanger, due to improper operation of the water treatment equipment and the water quality control is not up to standard, the unqualified demineralized water is injected into the heating system to decompose the calcium, magnesium and carbonate in the water into heat The precipitates of calcium carbonate and magnesium hydroxide adhere to the heated surface of the heat exchanger, forming a hard scale. Due to the poor thermal conductivity of scale, the heat exchange efficiency of the heat exchanger is reduced and the heat energy is wasted
3. The heat exchanger was not cleaned in time, and the scale filtration in the water was incomplete, resulting in the water from the water outlet not being completely filtered, and directly supplied to the user. General domestic hot water units are basically used for bathing. Long-term contact with the skin without fully filtered water will produce bad results for the human body and affect the health of the person.

YOJO is a heat exchanger manufacturer that produces various types of heat exchange equipment of YOJO brand. Among them, YOJO Fusion-Bonded Brazed Plate Heat Exchanger is made of 100% stainless steel material and has not been brazed with copper or nickel foil (similar to AlfaNova) .
