Cat has introduced two new mobile diesel rental generator sets, formed by adding ACERT technology to its XQ45 and XQ60 units to meet new EPA emissions requirements without sacrificing performance. These sets are for prime or standby power support.

Designed specifically for the rental market, they feature NEMA 1 steel, sound-attenuated, weatherproof enclosures with an internally mounted exhaust silencer and corrosion-resistant, rugged construction, including Class H insulation with coastal insulation protection. Security is built in, with lockable access doors to the safety glass control panel viewing window, fuel fill and maintenance-free battery.

The large doors and access panels for the controls are located together on the same side. The XQ45 and XQ60 feature an analogue control panel with full function instrumentation and safety features. The control panel has gauges for oil pressure, engine temperature, voltage, current, frequency, fuel level and battery voltage. Indicators give an alert for low coolant level, low fuel level or fuel leak, low oil pressure, overspeed and emergency shutdown.

Through ‘advanced fuel delivery strategies, air management and highly developed electronic systems’, the turbocharged C4.4 engines are claimed now to meet EPA Tier 3 non-road mobile applications emissions regulations without increasing fuel consumption or weight.

The XQ45 is rated at 45 kW (standby)/41 kW (prime) at 60 Hz, while the XQ60 is rated at 60 kW (standby)/53 kW (prime) at 60 Hz. Both generator sets offer switchable voltage output: 480/277 V and 208/120 V at three-phase and 240/120 V at one-phase. The generator sets are permanent magnet excited.

Both models include an integrated single-wall fuel tank and allow for an optional UL-listed double-walled fuel tank base. The tanks hold a minimum of 24 hours’ worth of fuel.
