NEW GAS-SMALL-SCALE CRYOGENIC ASU EXPERT

Professional EPC Contractor for Air Separation Units
NUZHUO offers more than just equipment.
We provide a comprehensive Turn-key Solution for oxygen production,covering the entire lifecycle of your project.
Custom Engineering: Tailored system design based on your altitude, humidity, and purity requirements.
Manufacturing & Testing: Strict quality control and factory acceptance testing (FAT) before shipment.
Logistics & Installation: International shipping coordination and on-site expert installation.
Staff Training: Technical workshops for your engineers to ensure seamless operation.
Lifetime Support: 24/7 remote technical assistance and rapid spare parts global delivery.
This entire set of oxygen production equipment has optimized the stability and balance of the distillation tower.
The intelligent control system conducts real-time monitoring of the operation status of the entire production line, including factors such as the pressure of the upper and lower towers, the liquid level of liquid oxygen, and the reflux ratio.
When the system is unstable in operation, it will give a warning and make adjustments. In case of a failure, it will try to maintain the purity of the gas as much as possible. The probability of failure is relatively low, such as liquid overflow and other types of failures.

High Efficiency & Low Energy: Optimized distillation column design ensures the lowest power consumption per unit of oxygen produced.
Stable Operation: Designed for 8,000+ hours of continuous annual operation with minimal maintenance.
Smart Control: Equipped with a fully automated PLC system, allowing for one-button start/stop and remote data monitoring.
Modular Design: Fast on-site assembly thanks to our skid-mounted and modular sub-system approach.
FAQ
01
Q1: What does the "Turn-key" service specifically include?
A: Our turn-key service means you only provide the site and power. Nuzhuo handles everything from air compressor selection, purification system design, cold box manufacturing, to the final commissioning and operator training. We deliver a ready-to-run oxygen factory.
02
Q2: How do I choose between PSA and Cryogenic oxygen production lines?
A: Generally, PSA is ideal for smaller scale (under 500 Nm³/h) and 93% purity needs. For large-scale industrial requirements or when 99.6% high-purity liquid oxygen is needed, our Cryogenic ASU production lines are the most cost-effective and reliable choice for long-term ROI.
03
Q3: Can Nuzhuo customize the production line for high-altitude regions?
A: Yes. We have extensive experience in adjusting air compressor ratios and cooling systems for high-altitude or extreme temperature environments to ensure the rated oxygen output is maintained.
