Cleaning of brazed heat exchanger (plate)
Application: Common applications of BPHE are heating, cooling and condensing.
Brazed Plate Heat Exchanger is mainly used in heating, cooling and condensing systems.

1. Effectively use diaphragm pump with sufficient pulsation capacity as circulation pump.
2. The circulating detergent temperature range is generally 20~50℃, the higher the temperature, the faster the dissolution.
3. The cleaning agent should be selected appropriately according to the attached scale (deposit).
4. The concentration and amount of detergent used should be adjusted according to the amount of scale attached.
▷ The plates are connected with copper alloy, and if they come into contact with free acids such as hydrochloric acid, nitric acid, or sulfuric acid, the joint area will dissolve and the liquid will pass through each other, causing the heat exchanger function to be inactive. lost. Therefore, it is necessary to use appropriate cleaning agents and effective cleaning methods. In particular, stainless steel is very susceptible to chlorine ions (Cl-).
Cham Clean provides scale removers that do not cause damage to the base material.

▷ Gentle cleaning scheme
Clean by temporarily connecting the circulation hose to the In and Out heat exchangers.
Various radishes and organic materials adhere to the plate-shaped plates
Before cleaning, samples are collected and dissolution tests are performed.
