Use guide and maintenance of tube-in-tube heat exchanger
Cautions in the process of using tube-in-tube:
1. The thread specification for inlet and outlet water pipe is G1-1/4.
2. To avoid foreign body into the system impacting performance and even leading to the
corrosion of the double-pipe heat exchanger, must connect water filter unit in the feed line
attachment, recommend mesh is 40 mesh per inch. And please according to the situation of
water quality, regular cleaning filter.
3. Should be used water pipe in accordance with local and national laws and regulations, water
pipe size is not less than double-pipe heat exchanger interface size (DN32).
4. In winter, if you don’t use for long time, be sure to discharge all the water in the system to
prevent frost crack system and close the power supply.
5. The water inside the double-pipe heat exchanger can be discharged through drain valve near
inlet water of the double-pipe heat exchanger.
6. According to the different tube heat exchanger and pipe scaling of water system, regular
clean the heat exchanger and water system to remove scale.
Suggestion: the water system set isolation valves in the appropriate position; it is convenient
to connect cleaning system.
