What is SmartSOFT?

Denyo SmartSOFT (Soft Starter) enables a smaller generator capacity to kick start a big motor load and offers uncompromising performance to meet your heavy-duty application needs. This unprecedented integration across two devices aims to provide a higher degree of versatility with the same reliability of our Denyo Generator.

How does it work?

Traditionally, starting a motor load with a direct start method requires at least three times the motor capacity when selecting the proper size generator. If an undersized generator is used, the high inrush profile contributed by the motor may prevent the generator from starting successfully.

A big capacity generator consumes more diesel for the same running load than a smaller generator. Continuous running of big generators supporting smaller loads (low loading) over a long period can cause unburnt carbon, resulting in sparks to be seen at the exhaust outle.

To solve the mentioned problems, the Denyo SmartSOFT system intuitively chooses almost an equivalent size with consideration for the average load factor. For example, a 37kW motor does not require a 125kVA generator, and only a 50kVA Denyo SmartSOFT is needed for the generator to start and work perfectly.

By selecting a matching size generator, low loading issues can now be fixed. On top of that, you will get to enjoy huge fuel savings – saving you cost and space in the long run.
