ASU Sold to Linde Group (China)

We are much honored to share you that we successfully deliver two sets ASU (KDN-2200(100Y) & KD0NAr-3000Y/1300Y (4400)/100Y) to Linde Group (China) in 2014. Both start their first operation and had reached productivity as the design expected. After years of effort, we become the strategic partner like linde, messer, praxair, air product etc. We would like to be one of your strategic partners too.

ASU Sold to Qingtuo for Indonesia project

We are much honored to share you that we signed a contract of 12500 Nm3/h O2 air separation plant with Qingtuo Industry Group in 2015. This project will be built in Indonesia.

ASU Sold to Cryoinfra (Mexico)

We are much honored to share you that we successfully deliver another set ASU to Cryoinfra (Mexico) recently. SASPG shook hands with Cryoinfra for the supply of 2nd ASU (Capacity: 1042TPD) in Dec 2012. It was the 2nd ASU that SASPG worked together with Cryoinfra, who is one of the biggest gas supply company in Mexico and a joint venture of AP. Now this 2nd ASU is successfully built and start running.


Q: What products I can order from your company?

A: We specialize in producing Cryogenic Air Separation Plant, LNG plant, CO2 Recovery Plant, Cryogenic Liquid Storage Tank (LO2, LN2, LAr, LCO2 and LNG), Semi-trailer Tanker, Vaporizer, VPSA/PSA Oxygen/Nitrogen Generator, Cryogenic Liquid Pump, Gas filling Station, Compressor and dry ice making/cleaning machines etc. Any interests you can feel to contact us for details. Thanks.

Q: What is your production standard? Can you manufacture your products under ASME standard?

A: Our company has obtained the A2 and C2, C3 Pressure Vessel Fabrication Certificates, Grade GC1 Pressure Pipe& Vessel Construction Certificates, ISO9001 Quality Certificate, ASME Certificate and U Stamp. So, if you ask for ASME stamp, we are able to manufacture your products under ASME standard.

Q: Have you supplied tanks to any renowned companies?

A: Our group company is a regular strategic partner of some big gas companies. We have supplied many storage tanks for them with different sizes. The biggest size we ever provided is 3000m3 ordinary pressure storage tank. We also made high pressure storage vessels for them, such as 100m3 LCO2 tanks, 10m3 (20m3, 30m3)LO2 (LN2, LAR) tanks.
As a giant cryogenic equipment company with more than 40 years history, we are a top two manufacturer producing air separation plants in China. The biggest air separation plant we have ever made is 60,000Nm3/h, famous for its advanced technology and reliable performance.

Q: What about warranty?

A: Equipment warranty is 12 months from the date on which the equipment is applied successfully into operation, or 14 months from the date on which the equipment has been delivered, whichever comes first.
Generally speaking, our cryogenic storage tanks can work normally for 15-20 years if it is maintained properly. As a leading brand in China with over 40 years history, reliability and stability of our tanks is much better than small young companies.
