VPSA Oxygen Generation Automatic Control Solution

Listing Short Intro

Full turnkey on-site oxygen plant solution with KYN28A-12 high-voltage cabinet, LV distribution panels, PLC & DCS centralized control, cutting your liquid oxygen procurement cost by 30%~45%.

The problem we need to solve

High recurring cost of bulk liquid oxygen delivery, unstable oxygen supply affected by logistics, manual onsite adjustment leading to low equipment efficiency and high power waste, lack of unified monitoring for full oxygen production line.

How Our System Solve Problems Step by Step？

1.Power Distribution Layout

We configure KYN28A-12 12kV high voltage switchgear for incoming high-voltage power of air compressors and large blowers; equip GGD fixed low-voltage cabinets, MNS/GCS draw-out distribution cabinets and reactive power compensation cabinets for auxiliary equipment power supply. The reactive compensation panel automatically tracks load fluctuation to improve power factor and cut invalid power consumption caused by frequent compressor startup/shutdown.

2.Drive Control Configuration

Heavy-load air compressors adopt our high voltage soft starter cabinet for smooth motor startup to eliminate huge inrush current impacting factory grid; variable-load blowers are fitted with HV VFD high voltage frequency conversion cabinet to adjust rotating speed in real time based on actual oxygen output demand.

3.Automatic Control Logic (PLC+DCS Core)

PLC collects real-time data of adsorption tower pressure, temperature, air intake flow and oxygen purity, automatically switching valve groups for adsorption & desorption cycles without manual intervention; DCS system centralizes all operating data on the central control room screen, realizing real-time parameter modification, abnormal fault alert and historical data storage.

4.Whole-cycle Project Service

Our team finishes electrical scheme design, cabinet pre-assembly & factory testing, overseas site wiring guidance, full system commissioning and after-sale remote troubleshooting.

Application & Benefits

Application: Metallurgy, ozone wastewater treatment, glass production, aquaculture, chemical industry, waste incineration.

Benefits: Self-sufficient continuous oxygen supply, cancel expensive liquid oxygen transport & tank storage, lower overall power cost, 24h unattended stable operation.
