Frequently Asked Questions
|
What emissions standard does the KDE72SS3 meet, and why is Stage V important?
|
| It fully complies with EU Stage V (Regulation 2016/1628), the strictest emissions rules for non-road diesel engines in Europe. This dramatically reduces NOx and particulate matter, enabling legal operation in regulated urban zones and across the EU without restrictions. |
|
How quiet is the KDE72SS3 in real-world use?
|
| Sound pressure level is 68–70 dB(A) at 7 meters – similar to normal conversation or a quiet office. High-density canopy, optimized air ducts, and premium residential-grade muffler make it suitable for hospitals, schools, residential areas, events, and other noise-sensitive locations. |
|
What is the actual fuel consumption and runtime?
|
| Fuel consumption is ≤ 235 g/kW·h (approximately 14.5 L/hour at full prime load of 52 kW; lower at partial loads). The standard 150L tank provides around 10 hours of autonomy at full load – perfect for overnight backup, construction sites, or extended rental use. Optional larger tanks extend runtime further. |
|
Can the KDE72SS3 be used with an ATS for automatic standby power?
|
| Yes – it integrates perfectly with an Automatic Transfer Switch (ATS). The built-in SmartGen 6120CAN AMF controller supports auto start/stop on mains failure and seamless power transfer for offices, shops, small data centres, or critical loads. RS-485/USB ports enable remote monitoring and ATS communication. |
