Air temperature regulating system is made up of a water cooler and an electric heater. The temperature of air compressed by fan is around 70 deg. Cent , passing the water cooler, its temperature is reduced to meet the requirements of process operation. Then it is sent into the adsorption towers. In winter, the temperature of air is to be increased by the electric heater and reaches the requirements of process operation.

Compared with three-tower process, oxygen generator with two towers can not produce consecutive oxygen, therefore, a buffer tank with large volume is needed for stable oxygen output.

* System process is achieved by DOS control system. In this system, valves switches are independently controlled by PLC (Programmable Logic Controller). Analog signals of test sensors communicate with the main control system through specific communication protocols. Relevant data of specific unit can be sent to main control system and remote control signals of main control system can be accepted by specific unit.
* In order to ensure safe oxygen supply, functions of interlink, protection, alarm, print, record etc can be provided.
* The output variation of oxygen supply can be adjusted by DCS control system. System operating parameters can be adjusted to save energy.
* The main control system adopts industry computer, provided with specific software and convenient human-machine touching screen, Start/stop and operating parameter collection can be realized on control panel. Remote monitor and print of running status record can be easily achieved.

* Quick and convenient start and stop
* Low investment and energy consumption
* High automation
* Simple operation and maintenance
* Short installation period and small ground treatment workload
