When will my generator require maintenance?2020-02-26T08:17:45+05:30

Maintenance of a generator depends on site/environmental conditions, fuel type, sulphur content etc. which may be more or less than what is stated in the engine/generator user guide. We do recommend regular check-ups to enhance the machine life.

How do I know what is the maximum and minimum load that I can apply to my generator set?2020-02-26T08:17:05+05:30

In order to avoid over load, a generator must not exceed 80-85% of its capacity and to avoid under load, a generator set must not operate below 40-45% of its capacity.

Could my generator operate at high ambient temperature and harsh environment?2020-02-26T08:16:23+05:30

Our generators are designed to work on normal and extreme climatic conditions. When operated on high ambient temperature, an amount of de-ration should be considered from the normal rating. Our sales team can provide you with the required details.

What is the difference between Prime and Standby Generator?2020-02-26T08:15:52+05:30

Prime Rating generators are the one intended to run without any restriction of running hour. Output of these generators can be of varying load to a peak demand of 100% for an unlimited time. A 10% of overload capability is allowed for emergency use for a maximum of 1 hour in 12 hours.

Standby Rating generators are the ones for supplying emergency power for the duration of normal power interruption. No sustained overload capability is permitted for this rating.

What size of a generator do I need?2020-02-26T08:15:13+05:30

The size of a generator is related to load type (inductive, resistive, liner, non-linear etc.), loading steps or sequences, application (Prime, standby, continuous) and operation location ambient conditions. In case of any difficulty, please contact us and one of our sales or technical staff will be more than happy to assist you.
