Verified technical answer

PSI 280 S / NG at a glance

PSI 280 S / NG is an industrial natural gas generator with 250,0 kVA / 200,0 kW PRP and 265,0 kVA / 212,0 kW ESP. Final selection requires the project load profile, operating mode and site conditions.

PRP output	250,0 kVA / 200,0 kW
ESP output	265,0 kVA / 212,0 kW
Voltage / frequency	400/230 V / 50 Hz
Fuel	Natural gas
Design	Soundproofed
Engine	PSI 13 L

What is the difference between PRP and ESP?

PRP is the prime power rating for the defined operating profile; ESP is the emergency standby rating. They must not be treated as interchangeable continuous ratings.

What is checked before selection?

Load profile, motor starting currents, voltage, frequency, operating mode, site conditions, noise requirements and transfer concept.
