The Technodinamika holding company, an affiliate of Rostec State Corporation, develops equipment to be used by the services of the Ministry of Emergency Situations of Russia and explorers during expeditions to the Arctic shelf areas. One of such items is AVM-21 Morzh diving apparatus being developed by Respirator scientific production enterprisem, a member of the holding company.

Diving into cold waters often poses a risk. The air exhaled by the diver is 100% humid at low temperatures. This could lead to frosting of the breathing apparatus and shut-off of the breathing mixture supply or switchback to continuous supply.

Advanced technical solutions allow Morzh to effectively solve this problem. New LAM-21 breathing apparatus and VR-172 regulator are designed for operation at water temperatures up to -4 degrees Celsius.

To make Morzh more reliable, it is equipped with breathing conduits that can be connected to the apparatus tanks independently of each other.

The apparatus has been developed primarily for underwater operations at low temperatures. Maximum operating depth of the apparatus is 60 meters. As envisioned by the developers, Morzh can be used by the services of the Ministry of Emergency Situations of Russia or for works at the Arctic shelf, and can also be installed on icebreaking fleet and platforms. It should also be noted that the apparatus allows to carry out underwater works under conditions of serious contamination, including oil spills.

The regulator of the diving apparatus has already been used in Arctic and Antarctic expeditions of the Russian Geographical Society. It also helped breaking the world diving depth records.
