2 turbodetander dt tur 1

Turbo expanders are used as a special expansion machines for systems that implement a refrigeration cycle is used in air separation plants for the production of "cold".

Consist mainly of: turbines, control Cabinet, lubrication system, control devices and regulation.

The process of expansion of the gas occurs in a centripetal turbine mounted on pillars with a circulating lubrication.

Gamma turbo-expander aggregates of low, medium and high pressure block design:

  • increased willingness to use the acquisition units of the unified stations of the lubricant;
  • one hundred percent factory-assembled - installation of equipment on a common frame.

Start with the workstation remotely.

Control system based on programmable controller S7-200 (SIEMENS).

Display the monitored parameters on the display of the workstation and control Cabinet.

Comprehensive testing in the manufacturing process of all the components on the stands.

Acceptance tests in the accredited testing laboratory for turbines and components.
