YGK Generator Products Introduction (presentation for collaborating companies)

Cases of social problems

Excerpt from infrastructure related news covering the 2011 Tohoku earthquake

  • People suffering from disaster experienced difficulties in requesting help due to failed communication systems
  • Information retrieval through the data communication network is important for the affected people to retreat safely and for the stability of life during evacuation
  • Communication network is important for residents in the disaster-stricken areas to collaborate
  • Due to the deterioration of light oil, many emergency generators did not work
  • Rescue of people affected by disasters may take several days
  • When the petroleum delivery infrastructure was damaged, electrical vehicles which could be charged using local energy were useful means of transportation
  • Need arose to depend on the water tank trucks of the self defense force when the water pipelines were damaged
  • When the water pipelines were damaged, dish-washing and the use of bathrooms were restricted
  • The use of heating equipment during cold weather was restricted when heating oil was limited
  • Large scale electricity supply restriction stagnated industrial production of affected areas
  • High capacity electricity supply is needed continuously in evacuation sites including hospitals and nursing homes

Solutions to social problems and YGK product areas

Small sized emergency generator 3kVA

Timing for installation

  • Based on the national resilience plan by the government, LPG emergency generator to be set newly or as replacement of diesel generator for traffic light system , designated refuge shelter and road message sign etc.
  • When the stores are newly opened or renovated
  • Early installation timing is recommended to reduce greenhouse gas emission

Superiority and technology of YGK 3kVA generator system

  • Use LP gas as fuel which is easy to get or stored for emergency
  • Reliable start by four-point ignition system
  • Automatic start within 20 seconds upon power failure and automatic stop when recovered
  • Enjoy stable power supported by the inverter control device
  • Continuous operation for more than 72 hours by the high efficiency power generation
  • Settable in narrow space or on the roof due to small size and light weight
  • Settable in the residential area due to high noise reduction and low vibration
  • Low CO₂ emissions, few NOx and SOx emissions
  • Resistant to disaster and easy maintenance due to the non-deteriorated fuel
