The specially treated temperature sensor has the same corrosion resistance as PTFE material. So, it can be directly immersed into the acid to measure the real temperature of the acid liquid instead of the heater. As a result, accurate temperature control ensures that the acid liquid maintains sub-boiling temperatures during the purification process.

Too high a temperature causes the decrease of the purity dramatically. Too low a temperature causes the unbearable low production.

Thanks to RTC technique and the state-of-the art structure design, AP300 is able to control the temperature accurately and reasonably and get the best balance between efficiency and effect.

AP300 uses the Peltier cooling technique to efficiently condense acid vapor. Compared with air cooling and water cooling, Peltier cooling has several advantages, such as excellent temperature stability, accurate temperature control (±1℃), water saving and no bacteria breeding.

Three non-contact liquid level sensors monitor the level of raw acid and purified acid in real time. Once the level of raw acid is too low, or the level of purified acid is too high, the system will be immediately stopped in order to avoid the dry running or the acid overflowing. The third sensor will stop the pump from adding too much acid into the purifier.

Automatic acid refill, removal and cleaning with the programmable pumps.

Despite the cost, the system incorporates two distinct flowpaths, each equipped with its own pump for filling and draining, respectively. This design completely prevents the contamination of the clean acid flowpath by the waste acid.
