1. Suppress and ensure that there is no leakage in the heat exchange equipment.
2. Isolate the heat exchanger system and drain the water inside.
3. Use high-pressure water to clean the impurities such as sludge and algae left in the heat exchange equipment.
4. A bleed valve needs to be installed above the heat exchange equipment.
5. Connect the transfer pump and piping and start pumping the required Fostek detergent to the heat exchange equipment (the ratio can be adjusted according to the specific conditions). The cleaning agent is pumped from the bottom of the heat exchange device and flows out from the top.
