1) the evaporator coils are staggered and formed by mechanical expansion, and the copper tubes and fins are closely combined with high heat transfer efficiency

2) The adopted fan is damp-proof, low temperature resistant, large in air volume, low in noise and stable and reliable in operation

3) An electric defrosting system composed of stainless steel pipes is adopted, and the electric heating pipes are directly inserted into the coil, so that the defrosting time is short and the effect is good

4) The shell adopts high-quality steel plate and plastic spraying technology, which has high strength, corrosion resistance, flat appearance and elegant appearance
