In most cases, the condensate contains oil and solid particulate impurities. If the compressed air condensate is not discharged out of the conveying and application equipment in time, these impurities will diffuse into the whole compressed air system, resulting in problems in operation, increasing production costs and damaging production equipment and products. The important responsibility of the post-treatment equipment is to remove pollutants and water from the compressed air. Leakage and inadequate control are the main reasons for the waste of energy consumption in the post-treatment system.

我们以往在使用定时器控制排放电磁阀时，同样也会出现压缩空气损失。因为定时器电磁排污阀采用死板僵化的定时工作方式，而不能根据冷凝液积存的实际数量控制排放的间隔时间和每次开闭阀门的精 准时机进行有用排放。当每次排污阀过多频次或过长时间打开时，很多昂贵且未经使用的压缩空气就立即被白白的泄漏到环境中去，特别在寒冷干燥的季节，这种情况造成的能耗浪费尤为严重。

In the past, when we used the timer to control the discharge solenoid valve, there will also be compressed air loss. Because the timer electromagnetic blowdown valve adopts a rigid timing working mode, it can not control the discharge interval and the accurate timing of opening and closing the valve for useful discharge according to the actual amount of condensate accumulated. When the blowdown valve is opened too often or for too long, a lot of expensive and unused compressed air will immediately leak into the environment, especially in the cold and dry season.

因为，冷凝液并不是有规律地产生和积聚。而是随着气候，季节，环境温度和湿度，每天的工作时段以及压缩机的加卸载转换与满载率等因素而随时发生着变化。只有准确实时地对冷凝液进行排放才能避免不必要的能耗浪费和损害。采用电子液位控制的高品质的零气耗自动冷凝液排水器正是通过电容式液位传感器实现了这个目的。智能液位电子控制系统有用的避免了压缩空气的损失，做到冷凝液的及时排放，并保证了小化输入电能的需求。

Because the condensate is not generated and accumulated regularly. However, it changes at any time with climate, season, ambient temperature and humidity, daily working hours, loading and unloading conversion and full load rate of the compressor. Only when the condensate is discharged accurately and in real time can unnecessary energy consumption waste and damage be avoided. The high-quality zero gas consumption automatic condensate drain with electronic liquid level control realizes this purpose through capacitive liquid level sensor. The intelligent liquid level electronic control system can effectively avoid the loss of compressed air, discharge the condensate in time, and reduce the demand for input electric energy.
