Gilkes have supplied a number of Francis turbines to the Unilever tea estate near Kericho in Kenya. The oldest turbines date back to 1929 and the most recent was supplied in 2009. The oldest turbines were supplied with mechanical governors. Over time the condition of these has degraded and spare parts have become difficult to obtain. Electricity generated from these turbines is critical for the processing of tea grown on the estate and security of supply is important.
With this in mind Gilkes were approached in 2014 to upgrade five of the turbines in 3 separate power houses on the tea estate. Detailed design & engineering was required for each turbine and in early 2016 a full upgrade to digital governors with new control panels and hydraulic control modules was carried out.
