FG Wilson is making its mark in India with a range of generator sets from 10 to 200 kVA, sourced and fully supported in India.

Choosing a generator set can be an important decision. FG Wilson, a UK-based brand has been in the business for more than 50 years, and is now making a mark in India with a range of generator sets from 10 to 200 kVA, sourced and fully supported in India, and all CPCB-II emissions compliant. As? Mithilesh Singh, Marketing Communications, FG Wilson ASIA Pacific, says, 'FG Wilson is a volume manufacturer, with 625,000 generator sets installed since 1990, which is as far back as our IT systems can look. And because we build for volume, we go to great lengths to ensure our products are as reliable as possible when they are working for their owners." That means a rigorous approach to testing before any FG Wilson products reach customers. 

Unmatched R&D
Singh says, "We have a modern Engineering Centre in the UK, built at $26 million, which houses our R&D facilities and also contains Europe's largest fully automated hemi-anechoic chamber, providing state-of-the-art acoustic research and test capabilities."

At the Centre, every new product design is tested for 500 hours on a resistive load bank and inspected throughout for design weaknesses which, if found, are then corrected before launch. This includes testing of full load power rating with testing of cold and hot load step to ensure the generator set can produce quoted performance.
Singh says this is important: "The 500 hour test determines the likely reliability of the generator set in a customer's environment, and the full load power rating allows us to validate the performance data of the engine. For us, the data from the engine manufacturer is a starting point and our test confirms the actual engine performance in the generator set when it is in action. It is not always the same as the standard engine data, and for us, it is important to make sure the performance data are exactly right for the customer's application."

Rigorous approach
Singh adds, "Designers of generator sets always face a constant battle to control noise and heat. It is a constant process of trade-off and design tweaks to get all three: Size, noise and cooling, where you want them. That means a designer needs a detailed understanding of airflow through enclosures and it is important in high ambient temperature environments. It is not difficult to put an enclosure around a generator set. It is more challenging to make it work in a high ambient temperature."

As part of product testing, noise pressure level is measured at 1 m and 7 m, and calculated from measurements on a hemisphere. This means that customers can be sure that the generator set has been properly tested and independently certified, and is within stated limits and not louder than expected.

At the same time, volumetric airflow is measured to ensure reliable performance at ambient conditions and to ensure that the generator set will not repeatedly shutdown due to high engine temperature.

The testing does not stop there either: It includes vibration analysis, alternator testing, water ingress testing, safety and serviceability audits and EMC testing to ensure generator sets do not interfere with other equipment. 

Once installed, FG Wilson generator sets are supported by a global parts operation that ships up to 3 million parts a year from a stocklist of 11,500 different parts.  
Singh avers, "Our formula is simple: Self-contained generator sets that are easy to install and operate, designed for a long and productive working life, supported by a wide and professional dealer network and which represent value for money."
