STATIONARY ENGINES

Gas Generator Sets with Engines of 22/28 Series

Gas Generator Sets with Engines of 22/28 Series


  • Gas generator sets are electric power sources for industrial enterprises and settlements in regions remote (switched off) from centralized power systems and also are reserve power sources at enterprises with continuous production processes.
  • Gas generator sets could operate both autonomously or in common network in parallel with other similar sets and mains.
  • Gas generator sets are installed at stationary gas power plants in enclosed, heated and ventilated rooms on common underframe and concrete foundation. They could be installed on shock-absorbers.
  • Gas generator sets could be completed with automatic remote control system permitting to maintain engines in "hot standby" and to start engines, load generator sets, enter them in parallel operation with other sets, control rotation speed and loading value in automatic mode.
  • Gas generator sets reliably operate under conditions of continental, arctic and tropical climate and in high mountains.
  • General arrangement of gas generator sets provides easy access to components and assemblies demanding periodical visual inspection and maintenance as well as repair ability. Generator sets are delivered in completeness with tools and accessories necessary for quick and qualified disassembling, assembling and repair.
  • High efficiency of sets on fuel and oil as well as small cost of providing service and maintenance provide minimal cost of energy unit output.
