Reliable Single Phase Diesel Generator

This single-phase diesel generator from Hyundai produces 22.5kVA of standby and backup power, powered by a water-cooled 4 cylinder HY490 diesel engine.

It's also a generator which is designed to provide years of reliable service, with low maintenance requirements and a user-friendly design. The slow running 1500rpm engine is stressed significantly less than faster engines during use, which makes it ideal for daily use

Diesel Power You Can Rely On

Hyundai is renowned for its high-quality generators and the DHY18KSEm provides exceptionally low running costs, thanks partly to the fact it can be powered by red diesel

It's built within a sound attenuated canopy, which lowers the noise produced to just 65dB at 7 metres. This canopy also provides the generator with protection from the elements.

It's also equipped with a digital control panel that makes it easy to monitor the performance of the generator, including the run time, voltage and frequency. 

Don't Rely On The National Grid

Sensitive electronic appliances, such as TVs, laptops, PCs and more can be powered safely by this generator, as it is equipped with an AVR alternator that produces a clean power output.

It's equipped with 3x 230V / 32A sockets and a busbar.

It can also be configured to work with an Automatic Transfer Switch (ATS), which will detect a loss of power from the mains, turn the generator on, and then turn it off again when power from the mains returns. ATS system sold separately.

Kerbside delivery included - please note - forklift required for unloading

All of our single phase generators have a kVA rating that is higher than the kW. This is because we have assumed the appliances you are going to power have a load factor/power factor of 0.8 - therefore the 'assumed' kVA rating of the load would be higher. This is industry standard and it is usually best to scope the right unit based on the kW.
