I believe everyone has heard about plate heat exchangers. We can tell from the name that the plate heat exchanger needs to be added with water. So the question is how do we prevent the plate heat exchanger from freezing in winter?

1. For the water meter installed in the outdoor water meter well, clean the accumulated water in the well to ensure that it is dry, and fill with sand, saw foam, etc. to the edge of the red copper of the water meter.

2. Insulation materials can be used to wrap tightly. The water supply facilities in the shade should be thickened and tied. For the roof water tank, the top cover of the water tank should be covered, and the upper and lower inlet pipes and valves of the water tank should be wrapped tightly with insulation materials.

3. For water pipes installed outdoors, use warm items to wrap the water pipes and valves. The protective material should be kept dry, not wet with water, and wrapped tightly and compactly, and then wrap it with a plastic bag or wrap it with a plastic tape. .

4. Carry out multi-system overhaul and maintenance of the secondary pressurized water supply equipment, and wrap the parts that are easy to freeze with insulation materials. Cover, prepare cold-proof and anti-freeze materials to resist the influence of various bad weather and ensure that the pump unit is always in good operating condition.

5. For frozen water pipes, it is advisable to turn on the faucet first, wrap the faucet with a hot towel, then pour warm water, and slowly pour warm water along the faucet to the water pipe to thaw the water pipe. Do not twist it or open it forcibly with a tool. If there is no water flowing out to the water meter, it means that the water meter is also frozen. At this time, wrap a hot towel on the water meter and sprinkle it with warm water to thaw the water meter. Do not bake it with fire to prevent damage to the water meter.
