Do not use a high-pressure water gun directly! The high-pressure water can instantly damage the fragile aluminum fins of the condenser, leading to a permanent decrease in cooling efficiency. We can only use a low-pressure air gun or a soft brush for surface cleaning.

We will provide a detailed logistics and insurance cost table from the port of origin to the destination port, but since we do not have access to the rapidly changing tariff dynamics of multiple countries, we cannot provide an absolute "Delivered Duty Paid (DDP)" calculation.

Demurrage is a penalty charged by the port or shipping company for not clearing and picking up goods on time after they arrive. To avoid it: send customs documents in advance and ensure the recipient is prepared with duties and import qualifications.
