Rebreathing systems designed by Technodinamika's Respirator Research and Development Enterprise (part of Rostec State Corporation) enabled the Alexei Leonov underwater research team of the Russian Geographical Society (RGS) to set the world record of the longest dive under ice. During the dive lasting over 10 hours the divers used VR-172 air pressure valves and LAM-17 lung-governed oxygen inlet valves.
The world record was set on January 30, 2019 in Kazan in Lake Izumrudnoye. The underwater research team of the Russian Geographical Society spent 10 hours 5 minutes under the ice. The divers went underwater to test the Russian equipment by simulating various emergency and abnormal situations.
'Today the key instruments to explore the Arctic are modern ice-breaker ships, mobile submarines and underwater vehicles. This means that developing and producing equipment for the use in the Arctic region is a key objective for Respirator RDE,' said the CEO of Technodinamika Igor Nasenkov.
At the moment, the holding produces pieces of equipment that have proven to be of great use in marine expeditions including those in the Arctic region. For instance, in March 2016 the members of the underwater research team of the RGS dived in the White Sea 102 m deep with the water temperature 1.5°С using VR-171S and VR-172 air pressure valves and LAM-17 lung-governed oxygen inlet valves.
RDE Respirator's design-engineering department has been developing rebreathing systems for divers since 2008. The VR-172 air pressure valve is designed to reduce the air pressure and letting it in the lung-governed oxygen inlet valve ensuring the rebreather's work at the depth up to 300 m. The LAM-17 lung-governed oxygen inlet valve is used in open-circuit scuba underwater breathing apparatus for air supply.
