The company has strong technological reserves and first-mover advantages in the field of gas separation membrane, and its researched and developed air separation membrane (oxygen-rich membrane, nitrogen-rich membrane) products reach international advanced levels. 

The company’s membrane separation environmental control system has such functional characteristics as active fire prevention (disruptive technology; changing passive fire fighting after the event to active fire prevention before the event; the fire cannot be ignited in the environmental control area, which completely walls up the fire risk from the source), habitability (Shanghai Institute for Physiology, Chinese Academy of Sciences, has conducted harmless experiments on human health), moisture-proof (water molecules are partially dissolved and separated through the membrane, and the humidity can be controlled to about 45%RH), dust and mold prevention (being able to filter PM0.01 microparticles, microorganisms, bacteria, viruses and other harmful substances; the clean gas can replace the fresh air function; and the nitrogen-rich and oxygen-poor environment at atmospheric pressure can effectively suppress the reproduction and growth of molds), anti-oxidation (the nitrogen-rich and oxygen-poor environment at atmospheric pressure can greatly delay the oxidation and aging of the protected items), and moth-proof (the oxygen concentration can be adjusted to below 6% regularly, the unlivable low oxygen environment, to disinfect insect, without residue or dropping liquid), etc. It is widely used in relatively closed places such as museums, archives, tobacco, traditional Chinese medicine, grain, data rooms, power transformation and distribution rooms, energy storage, hypoxia training, fruit and vegetable storage and preservation, coal mining, and other important material warehouses, etc.
