1. Isolate the equipment system and drain the water from the
Heat Exchanger.
2. High pressure water is used to clean the remaining silt, algae and other impurities in the pipeline, and the system is closed.
3. Install ball valves (not less than 1 inch =2.54 cm) between isolation valves and exchangers. both inlet and return outlets should be installed.
4. Connect the transfer pump and the connecting pipe so that the cleaning agent is pumped into the bottom of the heat exchanger and out of the top.
5. Start pumping the required Fustec cleaner into the condenser (the ratio can be adjusted according to actual conditions).
6. Repeat the cycle to the recommended cleaning time. With the progress of the circulation and the dissolution of the sediment, the gas generated during the reaction will also increase, and the excess air should be discharged through the vent valve at any time. With the discharge of air, the space in the heat exchanger will increase, and the appropriate water can be added. Do not inject a lot of water at the beginning, which may cause water overflow.
7. To check the validity of cleaning agents regularly in the cycle, you can use PH test paper. The cleaning agent remains effective if the solution is maintained at PH 2‐3. If the PH of the cleaning agent reaches 5‐6, an appropriate amount of the Forshitech cleaning agent should be added. The PH of the final solution remained unchanged for 30 minutes at 2‐3, proving that the cleaning effect was achieved. Note: Fostech cleaning agent can be recycled and reused, and discharges can be wasteful.
8. After reaching the cleaning time, recycle the cleaning solution. Rinse the exchanger repeatedly with water until it is clean and neutral. Use PH test paper to measure PH 6~7.
9. After cleaning, it can be turned on and run. You can also pressure test to see if there is leakage. If there is a leak, it can be repaired and protected by Mikka Wah polymer composite material, which can greatly extend the service life of the equipment.
10. After the equipment is stable, write down the current media flow, working pressure, heat exchange efficiency and other data.
