Turboexpander-compressor ADKG-10For low and medium flow rates
Up to 5 MM m³/h
Up to -170°С
Up to 13.5 MPa
Magnetic suspension
Basic information
The benchmark solution in its segment with proven performance and reliability for low and medium flow rates. It is the quintessence of our years of experience.
It is an essential element of technological designs and can be used to cool natural gas in low temperature separation cycles, fractional condensation separation, cyclo-ORC, dehydrogenation, liquefaction and other gas-bearing chemical processes.
It can be installed indoors at room temperatures of +5 .. +45 oC (UHL4 as per GOST 15150-69) and is designed as a monoblock with a horizontal shell connector. A single-stage centrifugal compressor and an axial turbine, usually single-stage with an inlet guide nozzle, are installed on the rotor of the replaceable flow part.
