EAS-1 Mobile Unit

In 2008 the unit was converted to dual-fuel and has since received the following new modernisations:

  • Switchable intake ductwork
  • Manifolds and burners to permit use of diesel fuel and natural gas
  • Woodward Atlas II dual-fuel controller that switches online from one fuel to the other
  • Beckwith protective relays for the generator and transformer
  • Gas Filter and valve skid
  • Diesel fuel pumps
  • Gearbox for operation at 50Hz (original 60Hz available as spare)
  • New blades in the Hot Section
  • Air filtration equipment
  • Fuel control/metering valves
  • Citech HMI
  • Woodward digital generator AVR (Exciter)
  • Lube oil cooler
  • Fuel filter/pumping skid
