Compressors are designed for compression of nitrogen and nitrogen-hydrogen mixture as integrated part of process lines of big volume ammonia production with the capacity of 200 000 tpa, as well as for carbonic gas compression in carbamide production process lines . 

Compressors are accomplished as horizontal, reciprocating, with four, five, six stages on opposite bases 4M16 and 4M40.
Automatic monitoring, control and protection system ensures a remote programmed start up and shutdown of the compressor.
Synchronous electric motor is used as driver. Reciprocating mechanism lubrication is of circulation type. Cylinders and rod seals are forced lubricated with pressure being produced by plunger pump. The unit is cooled by water.
