Purchasing Guide
Therefore, if you need a set of air separation plant, maybe you can probably tell us your specific requirements and environmental parameters so that we can make professional quotations accordingly.
Please advise:
1. First of all, altitude, temperatures (highest temperature in summer and lowest temperature in winter) and humidity, earthquake intensity and wind speed;
2. Moreover, voltage including high voltage and low voltage;
3. In addition, your requirements on the output and purity of liquid oxygen or oxygen gas that are as indicated below:
| Item | Product Output, Nm3/h | Purity Requirements | OSBL of Cold Box |
| Gaseous Oxygen (GOX) | | = | | % | barg |
| Gaseous Nitrogen (GAN) | | ≤ | | ppm O2 | barg |
| Liquid Oxygen (LOX) | | = | | % | barg |
| Liquid Nitrogen (LIN) | | ≤ | | ppm O2 | barg |
| Gaseous Argon (GAr) | | ≤
≤ | | ppm N2
ppm O2 | barg |
| Liquid Argon (LAr) | | ≤
≤ | | ppm N2

Packaging & Shipping
The transportation of large equipment, such as the air separation unit, LNG plant, and the CO2 recovery plant, has always been a concern of overseas customers. The unloading and lifting must be careful. How to reduce extra handling fees is also one of the issues to be taken into consideration.
We can provide you with a worry free delivery!
1. We maintain long-term cooperation with some partner forwarders. So we can,
a. Tell the accurate shipping date and quote the best shipping rates.
b. Book appropriate cargo space and choose the best shipping method, such as, container, roll-on-roll-off ship, open top container or bulk carrier.
c. Make appointment for commodity inspection, arrange shipment, and prepare necessary documents for customs clearance.
3. We are quite experienced in loading and fixing containers, protecting the cargo from any possible damage on the way. The cargos will be in perfect condition upon the arrival at the destination.
4. The bulk ship and roll-on-roll-off ship are for the delivery of large and bulky cargos. The destination port may not be equipped with large cranes, and at somewhere the lifting charges are quite expensive. Taking these factors into consideration, we will choose ships equipped with cranes to reduce costs for customers. Our forwarder will arrange appropriate crane lifting and attach the cargo to the deck or cabin.
5. We will track the delivery until you receive the cargo.
6. The vast majority of customers receive cargos intact, but there is still likeliness of slight painting scratches. In this occasion, we suggest customers to fix the paint on their own if necessary. In addition, customers may purchase transport insurance to further reduce the risk of cargo damage.
