EPS 20kW Standby Generator

20 kW & 40 kW Emergency Stationary Generators

These generators are powered by an Emergency Stationary Reciprocating Internal Combustion Engine (RICE) as defined in 40 CFR § 63.6675 “to provide electrical power…during an emergency situation.” Therefore this generator may not be operated for maintenance and non-emergency situations in excess of the limits outlined in 40 CFR § 63.6640. 

These EPA regulations require the unit be installed permanently in a stationary location and, therefore, this unit may not be used in mobile applications under penalty of law as outlined in 40 CFR § 1068.101 (b)(3). When installing this unit, the user should also ensure compliance with all state and local ordinances pertaining to this type of equipment.

Mounting Requirements

Concrete Pad

Most local regulations will require the generator be mounted to a suitable concrete pad. Mounting holes are provided throughout the length of the generator for this purpose. Additionally, the installer should consider mounting the unit at least 12” above grade to permit adequate access to the oil drain when service is required.

Consider the Cooling Air Flow

It is very important to choose a mounting location that will provide adequate cooling airflow into the generator, while also allowing the warm air to be discharged. This is the most important part of the installation from a performance and longevity standpoint. A minimum of 24 inches of space around the entire genset enclosure is recommended.
