Emission Requirements For Standby Generators

ย 

For most applications that utilise diesel generator sets, it does not have to comply with any emission requirements when:

  • Unlimited operation for emergency power supply on standby mode
  • Non-emergency operation of up to 100 hours per year
  • Major Power Source โ€“ The generator complies with emissions regulations. All major engine manufacturers publish individual emission charts. These charts reflect the EPA tier the engine is certified for.ย

What are Emissions?

The exhaust of a diesel engine contains by products from combustion. For environmental safety, the below emissions are monitored:

  • Nitrogen Oxide (NOx) โ€“ Occurs naturally as a result of bacterial process, biological growth, decay, lightning, forest fires and burning of fossil fuels. Colorless non-toxic gas (referred to as laughing gas).
  • Hydrocarbons (HC) โ€“ Organic chemical compounds that consist entirely of carbon and hydrogen. They range from simple molecules such as methane to polymers such as polystyrene.
  • Carbon Monoxide (CO) โ€“ Colorless, odorless, toxic gas produced from incomplete burning of fossil fuels.
  • Particulate Matter (PM) โ€“ The sum of all solid and liquid particles suspended in the air.
ย 

We have developed low emission diesel generators that can meet Tier 3, Tier 4 Final and EU stage V regulations. They are widely used in those places where it has strict requirements for pollution.
