22.5kVA Diesel Generator

Hyundai 22.5kVA Diesel Generator – Silent Single-Phase Backup Power

22.5kVA Diesel Generator

The Hyundai 22.5kVA Diesel Generator (DHY18KSEm) is a powerful and efficient single-phase generator designed to provide reliable electricity for homes, offices, farms, retail stores, and small industrial applications. Delivering stable backup or prime power, this generator is ideal where dependable single-phase electricity is essential.

Reliable Single-Phase Performance

The DHY18KSEm delivers:

• 20kVA / 16kW Prime Power
• 22.5kVA / 18kW Standby Power
• Single-phase 230V output
• 50Hz frequency with unity power factor

This makes it suitable for powering household appliances, office systems, refrigeration units, security equipment, and light-duty machinery.

Powerful Hyundai HY490 Diesel Engine

At the core of this generator is the Hyundai HY490 4-cylinder water-cooled diesel engine, designed for long operating life and dependable performance.

Engine highlights include:

• 1500rpm low-speed operation
• 2.5L engine displacement
• Mechanical governor for stable output
• Fuel consumption approx. 6.2L/hour at full load
• 77.5L fuel tank with up to 12.5 hours runtime

The slower 1500rpm operation reduces engine stress and improves durability compared to high-speed generators.

Clean Power with AVR Alternator

The brushless alternator with Automatic Voltage Regulation (AVR) ensures clean and stable power output, making the generator safe for sensitive electronics such as:

• TVs and entertainment systems
• Computers and networking equipment
• Security systems
• Office equipment
• Refrigeration appliances

Silent Weatherproof Canopy

The generator is enclosed in a sound-attenuated, weatherproof canopy, producing approximately 65dB at 7 metres, making it suitable for residential areas and commercial environments where low noise levels are important.

Hyundai’s canopy also features electrophoretic anti-corrosion coating, ensuring long-term protection against environmental conditions.

Intelligent Control Panel with ATS Compatibility

Equipped with a ComAp MRS10 control panel, the DHY18KSEm allows easy monitoring of generator performance and safety parameters through a clear digital interface.

Monitoring features include:

• Engine temperature
• Oil pressure
• Battery charging status
• Voltage output
• Operating hours

The generator is fully ATS compatible, allowing automatic startup during power outages and shutdown when mains power returns—ideal for installations requiring uninterrupted electricity.

Built for Long-Term Operation

Operating at 1500rpm, this generator is ideal for:

• Daily prime power applications
• Standby backup installations
• Residential and commercial environments

Diesel fuel also offers better storage stability compared to petrol and allows operation using cost-effective red diesel where permitted.
