Tubular air heater VPT-1200 and VPT -2000 are designed to heat the cyclic air after the compressor by the heat of combustion products after the power turbine of the gas pumping unit. They can be used both in the creation of new and in the modernization of existing gas compressor units to replace failed regular plate air heaters. VPT-1200 is used with the GT-750-6 unit, VPT-2000 is used with the GTK-10-4 unit.

Benefits of VPT:

  • Increased efficiency;
  • Reduced gas consumption;
  • Reduced operating costs;
  • The modular design allows for faster delivery and installation;
  • Maintenance ability in the conditions of a compressor station.

General arrangement

The gas air cooling unit is designed to cool gaseous media as part of oil and gas industry facilities within:

  • Working pressure, MPa (kgf/cm2)  - through 5,0 - 7,5 (through 50,0 - 75,0);
  • Working temperature, C(°С)   - through 323 - 348 (through 50,0 - 75,0).

The devices are manufactured in terms of design in two versions:

  • autonomous apparatus;
  • joining devices assembled into blocks of two or more devices.
