Product Description

　　Product Features
　　Designed for preservation, freezing, and refrigeration;
　　The shell is made of high-quality steel plate, with a sprayed plastic surface, corrosion resistance, and beautiful appearance;
　　The coils are arranged in a staggered manner, using mechanical expansion to ensure a tight connection between the copper tube and the aluminum sheet, resulting in good heat exchange;
　　High-quality stainless steel electric heating tubes are evenly distributed in the coils, resulting in good defrosting effect; The electric heating tube defrosting uses an electric heating aluminum sleeve tightly attached to the fin holes, which is easy to dissipate heat and has a long lifespan;
　　The design width of the air cooler is reasonable, and the distance between the fan blades and the aluminum fins is greater than 1/3 of the fan blade diameter to ensure sufficient effective air volume;
　　Technical Parameters of High-Temperature Standard Ceiling-Type Air Cooler
　　*For applications where t库=-25℃, △t=10℃, the R134 energy needs to be multiplied by the correction factor f, QOR134a=QOR22Xf.*
