    Basic information

    A balanced solution for medium and large flow rates, combining a proven design with increased productivity.

    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 C (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.
