A new direction in the work of our company is
upgrading and repair of compressors to provide the productivity not lower than in project and
increasing of the efficiency (1-1,5%) while reducing energy costs, increasing of number of
maintenance intervals and reliability. 
Modernization
of equipment is carrying out on a production basis NE "Energomash" Co. Ltd., repairs - at the
customers. This scope of work is recommended to perform for compressors with significant
operating time. Upgrade provides the improvement of parameters of a compressor, and its stable
maintenance, and includes: changing the design of the rotor, replacement of diffusers and
diaphragms, constructive change of tubes in tube bundles of the terminal and intermediate
coolers, changing the gear ratio of the gear pairs to change the speed of the compressor, the
replacement of bearing shells.
Modernization of the turbo compressor units of K-250 type.

Modernization of the compressor and auxiliary equipment includes:
- Changing the design of the rotor and the compressor housing;
- Replacement of diffusers stage I;
- Constructive change of tubes in the tube bundles of the terminal and intermediate coolers;
- Changing of the transmission ratio of gear pairs to change the speed of compressor (11230/77500 rpm);
- Replacement of liners and bearings.
Rotor compressors K-250/500 which are in use at the customer must be upgraded. The company has exchange fund.

Before performing this type of work, a technical audit of the condition of compressors carries out, to determine the complete list of works at a customer.
Installation supervision, commissioning, technical guidance and participation in acceptance testing of the supplied equipment are carrying out by supervisory personnel of NE "Energomash" Co. Ltd While normal operation of the compressor, there is no need for medium and major overhauls in the next 3-5 years.
