Freezer price, how to screen quality to control cost performance?

1. When purchasing the freezer, the customer can ask the site to try it first. The boot trial is not to test whether the freezer is operating normally, but in the process of listening to the operation of the refrigerator as a whole and whether the sound produced is large, based on whether it can be heard within 10 cm. 2, buy reliable quality freezer, first measure the performance of the necessary raw materials and components of the freezer. It's okay to consider more from the technical level and the use of raw materials. The selection of parts, especially key parts, has a great influence on the service life of the freezer. High-quality freezer uses pure copper tube, imported coated steel plate and other high-quality components to ensure the service life of the refrigeration system and the rust resistance of the commercial freezer. Check whether the side wall, compressor, joint and other small parts of the freezer are completely free of problems. 3. As an important production and operation tool, the freezer is not only time-consuming and laborious, but also causes economic losses if it is often repaired. In particular, the quality of the core compressor of the freezer must be excellent enough. 4. Refrigerator price insulation effect: the thermal insulation performance of thermal insulation layer in the production process of commercial refrigerator is not only an important quality index of refrigerator, but also an important factor in the use economy of refrigerator. 5. Selection of refrigerator body plate: whether the quality is excellent and the service life is long, selection of plate is the key factor. The skeleton part of the cabinet mainly depends on whether the welding points are firm and fine; The thickness of the cabinet plate should be paid attention to. If the plate is in the load-bearing part, the load-bearing capacity of the plate should be paid attention. The thermal insulation material is foamed with polyurethane under high pressure.
