1. Better materials: High-quality refrigerated display cabinets use imported stainless steel plates with a thickness of 0.5 or 0.8 millimeters. All evaporator tubes are made of high-quality copper coils and processed into wide, irregularly shaped tubes. The imported stainless steel plates have a smooth surface and uniform thickness. Using the appropriate thickness ensures a long service life and a flat and sturdy appearance for the refrigerated display cabinet. Copper tubes have better cooling efficiency and corrosion resistance than aluminum or composite tubes. High-quality copper coils have the advantages of high internal cleanliness and fewer pipe joints, effectively preventing leaks or blockages in the refrigeration system. Processing the round tubes into rectangular shapes changes the contact between the evaporator tubes and the inner liner from point contact to surface contact, increasing the heat transfer area and accelerating the cooling speed.
2. Commercial-grade high-power compressors: High-quality refrigerated display cabinets all use commercial-grade compressors. Commercial compressors have excellent starting performance and a wide range of cooling capacities, allowing for different configurations to meet different product requirements. Only commercial compressors can withstand the harsh operating environment, frequent starts, and long operating times characteristic of commercial refrigerated display cabinets, thus ensuring product quality. Although commercial compressors are more expensive than household compressors, their failure rate is less than 0.2%.
