Latest Generator technology, why is this important? If you just need a generator to run once a year maybe not, but if you need a generator to really standby we recommend quality and the latest technology to be built into your generator!

First off all, fuel economy, like in the old days generator engine technology was less advanced before, and therefore not all the engines was fuel efficient, today we also have fuel emissions standards especially in Europe and Western Countries, today you save money on running costs because of fuel efficient and advanced design engines and components! Brushless Diesel Generators, no need to maintain the alternators, saves time and money. Digital AVR, for a reliable voltage band, and generator monitoring. Laser cut silent generator bodies and chassis; do you need a generator body part? We can supply any Generator parts for all our diesel Generators. Generator Controller Technology, programmable options to suit your needs. Generators synchronization options available. Generator technologies that work for you! Our diesel generators will deliver!

Key factors about diesel generators: first is its speed, you get 3000 rpm and 1500 rpm diesel generators, this determine the frequency at 50Hz. 60 Hz generators runs at 1800 rpm with a 4 pole alternator. We specialize in generators that use diesel fuel. The advantage of diesel is, the generator is more fuel efficient than petrol generators, and is easier to store. Diesel engines use a fuel injection system to get the fuel into the combustion chamber, where petrol generators mostly still use a carburettor, especially the cheaper models. You get petrol engines that is fuel injected, but it is on the more advanced engines, not common with small generators. Another factor is reliability, low speed generators is bigger and heavier than the 3000 rpm sets, but at this low speed ensures a longer life span, and much less noise that the high speed generators. We specialize in low speed silent diesel generators. Our generators is manufactured with the following in mind: reliability, silent, compact, easy to maintain, competitive price and after sales service. Contact Us today for the best diesel generator prices and quality service.

We have tested our complete range for durability and load, we only work with prime power as a basis and you can be assured that when we specify a generator on a specific Kva at prime rate, that machine will deliver that specified rate constantly. The alternator and engine has been tested on proto development and is certified. Our stainless steel fuel tanks is pressure tested and certification is available on request.
