Compressed air system is the most important equipment is perhaps after cooler.

压缩空气系统中最重要的设备也许就是后冷却器。

After cooler work principle is that use of the cooling medium (such as water or air) and after cooler the exit of compressed air temperature difference.

后冷却器的工作原理在于利用了冷却介质(如水或空气)与后冷却器出口处压缩空气的温度差异。

After cooler out at the exit of compressed air temperature should be saturated steam, and air temperature should be pressure of compressed air condensation point.

后冷却器出来的压缩空气在其出口温度下应该是水蒸气饱和的，且气流温度应该是压缩空气的压力凝露点。

Oil filter can be placed in steam regenerative dryer, but the front after cooler can also reduce the amount of oil steam and prolong the service life of the molecule.

油蒸气过滤器可以安置在再生式干燥器的前端，但后冷却器也能减少油蒸气的量，从而延长干燥剂的使用寿命。

For example, water-cooled after cooler water temperature of 200 f, import export temperature of 600 f, compressed air after after cooler temperature dropped to 80 ~ after 200 f.

例如，水冷式后冷却器的进口水温200f，出口温度600f，压缩空气经过后冷却器后温度下降至80 ~ 200f。
