The Stelvio-S 22.5 kVA (18 kW) Three-Phase Gasoline Generator is a high-power, robust, and reliable piece of equipment, specially developed for intensive professional, industrial, or energy-intensive construction applications.
Designed to supply three-phase current (400V) with a maximum power of 22.5 kVA and a nominal power of 21 kVA, this generator guarantees stable and continuous power to supply large machines, power tools, industrial equipment, or emergency systems.
This model is equipped with a GENERGY SG1000 PRO, gasoline-powered, with a 999cc V-twin engine, air-cooled, and electric start. It complies with the EURO V emissions standard, ensuring energy efficiency and a lower environmental impact. Electronic engine management ensures quick starting, reliability in all conditions and precise power regulation. Includes three-phase copper alternator, SVR voltage regulator for stable current, overload protection, oil sensor with automatic shutdown and high-sensitivity differential protection (30mA). The reinforced steel structure, the full control panel with multifunction digital display, and the transport kit with wheels make this generator easy to maneuver, even in demanding environments.
2. LONG AUTONOMY - Large capacity tank for greater autonomy without the need for frequent refueling.
3. MULTIFUNCTION SCREEN - Digitally displays voltage, frequency and operating hours (partial and accumulated). In addition, it alerts the user when maintenance work is required.
4. S VERSIONS (RENTAL – PUBLIC WORKS) - Equipped with a 30mA differential, IP67 sockets, and an emergency stop button, according to our customers' requirements.
5. COPPER-WOUND ALTERNATOR - Alternators with high-quality copper winding and optimized cooling. Greater resistance to corrosion and overheating,prolonging the equipment's lifespan.
6. SVR – INTELLIGENT VOLTAGE REGULATOR - Greater motor starting capacity compared to older AVRs. For example, it allows starting single-phase motors up to 2.2kW (3HP) on 3kW generators. This technology also offers greater overload protection.
