冷干机是对压缩空气进行后处理，因此选型规则根据空气压缩机提供的技术参数来选。主要的参数有以下几点:
Baoding cold drying machine, the cold dry machine is the compressed air after treatment, so the selection rules according to the technical parameters provided by the air compressor to choose. The main parameters are the following:
1.空气压力：冷干机主要处理空气净化部分于蒸发器中实现，蒸发器为三类压力容器。按工作压力分有低压型（0.3-0.6MPa）、普通型（0.6-0.95MPa）和中、高压型（≥1.0MPa）三类，且市场空压机压力从低到高种类非常繁多，冷干机压力选型和储气罐一样，按照空气压缩机产生的空气压力进行选择冷干机的压力类型。一般我公司正常生产都为1.0Mpa下机型，如果高于1.0Mpa上机型需特别定制。
1. air pressure: the cooling dry machine mainly deals with the air purification part in the evaporator, and the evaporator is the three type pressure vessel. According to the working pressure is low (0.3-0.6MPa), ordinary type (0.6-0.95MPa) and high pressure (more than 1.0MPa) three, and the market pressure of air compressor from low to high are very diverse species, cold and dry machine pressure type and gas tank, selection pressure type cold dry air pressure produced by machine air compressor. In general, the normal production of our company for the 1.0Mpa model, if higher than the 1.0Mpa model needs to be specially customized.
2.空气处理流量：压缩空气流量不可超过额定处理量的10%。一般选型时冷干机稍可选则大于空压机排气量，这样空气处理效果更加。我公司接受 0.5~500 M3/min 及更大气流量机型的定制。
2. air treatment flow: the compressed air flow can not exceed 10% of the rated capacity. In general, the cold dry machine is slightly larger than the air compressor, so that the effect of air treatment is more. Our company accepts the custom of 0.5~500 M3/min and the more air flow model.
