After nearly 23 years of unremitting creation and technical innovation, PKU Pioneer's VPSA & PSA oxygen generation technology has been updated multiple times and many improvements and optimizations have been achieved in the reliability, stability and automation degree of VPSA and PSA oxygen generation units.

1. One-Button Start-Up

Press the sequence button in the control room and synchronously start the motors and valves to start up the VPSA oxygen production equipment, thus reducing the start-up time and saving the operation cost of the oxygen system.

2. Turndown Ratio Regulation

Make the blower and vacuum pump stop and the valves enter a stagnant state during specific periods by modulating the time of the suspension step in the sequence to finally control the oxygen capacity and meanwhile, save a certain amount of power consumption to meet the user's flexible oxygen flow requirements.

3. Adsorber Switching

To automatically switch adsorber vessels instead of shutting down the whole set of VPSA oxygen systems during malfunctions. When a multi-tower VPSA oxygen unit is in operation, in case a certain blower or pump, and the corresponding valves fail, the oxygen unit will automatically switch to the two-tower operation to ensure only capacity reduction without shutting down, therefore, customers will have sufficient reaction and treatment time for troubleshooting and the operation reliability of the oxygen unit is improved.

4. Automatic Regulation to Reduce Effect of Temperature Variations

Due to the fact that large ambient temperature differences between day and night in some VPSA oxygen production projects will lead to large fluctuations in the oxygen flow rate and purity, PKU Pioneer proposed an automatic adjustment solution for capacity and purity regulation, which has been realized by the PLC control program. The automatic solution minimizes the fluctuation ranges to significantly reduce the influence of temperature changes on the capacity and purity of VPSA oxygen generation, thus promoting stable oxygen production and supplying steady oxygen for the downstream processes to save great operation and maintenance costs for customers.

5. Factory Ventilation

Automatically control the fan switches in the workshop based on the workshop temperature and oxygen intensity to ensure the reasonable supply of feed air and suitable temperature inside the factory for the stable operation of VPSA oxygen equipment.

6. Pioneer Cloud System

Through intelligent data collection device, PKU Pioneer achieved real-time collection and recording of the project site data, based on which PKU Pioneer provides customers with regular diagnoses, advanced predictions and online support services. Oxygen plant managers are able to monitor the operation of the VPSA-O2 equipment by viewing the data in real time on mobile phones or computers, and PKU Pioneer technicians can assist users in analyzing and solving problems after sharing the information.

PKU Pioneer will continue to make innovations in oxygen plant automation upgrading and make continuous efforts to realize the bright vision of intelligent and independent VPSA & PSA oxygen factory with automatic operation, smart indicator optimization, automatic fault diagnosis and intelligent emergency treatment. People won't need to participate in the routine monitoring and operation, and only regular report inspection, periodic maintenance and typical emergency handling are needed. We'll strive to transform to intelligent manufacturing industry and promote the green, high-quality and sustainable development of the social economy.

For nearly 23 years, PKU Pioneer has been committing to providing customers with VPSA oxygen generation equipment with advanced technical capabilities, high safety and reliability, high energy efficiency, and higher automation degree. Outstanding technical advantages and comprehensive competitiveness have been developed in the field of VPSA and PSA oxygen generation. Up to now, PKU Pioneer has built 300+ sets of VPSA O2 units around the world. With the total oxygen capacity exceeding 1,500,000Nm3/h and the total flow rate of the extra-large VPSA oxygen unit in a single iron & steel mill reaching 87,500Nm3/h, PKU Pioneer is the hidden champion in PSA & VPSA industry.
