Durable Aluminum Enclosure for Harsh Environments

The generator is protected by a heavy-duty aluminum enclosure generator housing designed for outdoor installations.

The enclosure provides several important benefits:

• Wind resistance up to 186 MPH

• Weather protection against rain and debris

• Reduced operating noise

• Corrosion resistance

For coastal regions or environments exposed to harsh weather conditions, aluminum enclosures offer superior durability compared to standard steel housings.

The sound-attenuated design also ensures that the generator operates quietly, making it suitable for commercial areas where noise regulations may apply.

Fuel Flexibility: Natural Gas or Propane

The propane standby generator configuration allows users to operate the KG80 with either natural gas or liquid propane.

Fuel consumption levels include:

Natural Gas:

• Full load: 1202 cubic feet per hour

• Half load: 803 cubic feet per hour

Propane:

• Full load: 14.7 gallons per hour

• Half load: 7.7 gallons per hour

Natural gas is often preferred for permanent installations connected to municipal gas lines. Propane offers flexibility for remote locations or backup fuel storage.

This dual-fuel capability increases reliability because facilities can select the most accessible fuel source.

---

Safety and Compliance Standards

The generator meets several major safety and performance certifications required for commercial power systems.

These include:

• UL-2200 listing

• NFPA 110 Level 1 capability (with accessories)

• US EPA stationary emissions certification

NFPA 110 Level 1 compliance is particularly important for facilities such as hospitals and emergency response centers, where standby generators must start automatically and supply power immediately during outages.
