How to choose when buying a cooler

  Air coolers rely on water to evaporate for cooling and cooling. Nowadays, the market volume is very large, and a large number of air coolers are used in workshops, factories, restaurants and other industrial and commercial places. As a consumer who doesn't know much about equipment, how do you choose to buy high-quality and low-cost products? Most non-professional consumers are dazzled, and the products on the market are mixed. We will sort out the main points of choosing products for everyone:

  1. The appearance of the product is neat and the workmanship is precise.

  2. The trademark is complete (do not have a three-no product without a trademark), not a labelled product.

  3. The nameplate parameter specification is detailed.

  4. There is factory address information and can be consistent with the product trademark (now the Internet is developed, you can directly search on the Internet).

  5. There is a 3C certification mark required by the country (a necessary certification for electrical products).

The above-mentioned content can be seen and understood by most consumers. The quality of products that can achieve the above items is generally not bad. Of course, the latter is to identify whether there is fraud and whether it is an official authorized sales channel. .
