Precautions for shutting down industrial chillers in winter

Thank you very much for choosing our products. With the coming of winter, some chillers will be stopped. In order to ensure the normal operation of your chiller, please take the following protection after shutdown:

Dear customers of Lechang Refrigeration:

1. Turn off the water source of the chiller, and blow dry the water inside the unit components and pipes to prevent residual water from corroding the unit components after shutdown, or freezing and heaving at low temperatures; in addition, unscrew the drain nut under the water pump to drain the remaining water in the water pump to avoid freezing of the cooling water due to low ambient temperature, causing the evaporator to burst, causing refrigerant leakage, damage to the water pump impeller, and other failures.

2. Turn off the power and check the wear of vulnerable parts. If the wear is serious, record it and replace it with new ones before using it again.

3. Clean the fan of the air-cooled chiller and keep it in a clean state.

4. For the water tank of the water tank coil evaporator, check whether there is scale and other impurities and dirt. If there is any impurity and dirt, it should be treated with physical and chemical cleaning methods.

5. Understand the usage of lubricating oil through data recording, and replace the lubricating oil regularly according to the frequency of use, equipment operating status, etc. to ensure the good operation of the compressor.
6. Check the insulation effect of the chilled water pipes of the chiller and whether the insulation cotton is aged and damaged. The chilled water of the chiller needs good insulation to reduce the loss of cooling capacity. It can also avoid the formation of condensation on the outer wall of the pipe and reduce the impact of external temperatures at different temperatures.

7. Clean the surface of the chiller. After the equipment is shut down, use cleaning tools (cloth strips, neutral detergent, etc.) to clean the surface of the unit. After it is dry, cover it with a cloth cover, film, etc. This can effectively prevent dust from adhering to the unit and facilitate its use in the coming year. On the other hand, good equipment cleaning will help extend the service life of the equipment and make it more stable and safer to use.
