The Navy's "500m saturation diving project" is a national key scientific and technological research project, representing the highest level in China's saturated diving field. In 2008, Hongyuan company cooperated with Shanghai Naval Medical Research Institute to overcome technical difficulties and successfully rebuilt the "500m saturation diving equipment". It passed the test and acceptance of relevant national departments, and was highly praised by Navy officers and soldiers and relevant experts!

       The equipment adopts the international advanced computer automatic environmental control technology to realize the synchronous automatic regulation and control of temperature, humidity and CO2 content in the cabin under different pressure environments; adopts advanced mixture gas supply and helium recovery technology to realize the automatic supply of different proportions of mixture gas and helium recovery and reuse under different pressure environments; and adopts advanced permanent magnet Coupled induction drive circulating air supply system realizes the circulation and replacement of air in the cabin under high pressure environment; it is equipped with advanced computer-controlled multi terminal, wireless transmission multi parameter vital signs monitoring system, wireless transmission audio and picture synchronous projection system which can be remotely controlled in the cabin, and the advanced saturated diving breathing equipment produced by Morgan company of the United States.

       The whole set of equipment has advanced design, exquisite technology, safety and reliability, reaching the international advanced level.
