"Degassing unit of MDU-180RV was put into operation at the mine «Bolshevik», on 20 September, 2010. The unit is equipped with Italian pumps RVS 60, Robuschi factory. The capacity of a single pump is 60 cubic meters of methane-air mixture per a minute. Today the operating mode is three pumps in operation, another one is in reserve. We were attracted by the technical parameters of the degassing unit MDU-180 RV, the most important of which is the ability to pump methane-air mixture with a methane concentration of from 0 to 100 percent.

We are satisfied with the unit operation and at the moment the contract for the supply of another similar unit is concluded"
