GILBERT GILKES & GORDON LIMITED  

Gilkes are the original designers of the Turgo Impulse Turbine. Designed in 1919 by the Grandfather of Gilkes current Chairman, the Turgo concept was a side entry impulse turbine which would run, typically, at twice the speed of a Pelton turbine when operating on the same head.  With a power output of up to 10MW and a head range of 100-300 Mtrs the Turgo is available as horizontal, single and twin jet designs.

In todays market the Turgo is ideally suited to Run of River, Rural Electrification and Energy Recovery Porjects.

Gilkes manufacture Pelton turbines with a power output up to 20MW, with a head range of 100 - 1000 Mtrs.   Horizontal arrangement come in single and twin jet designs and vertical arrangements with p to 6 jets.

Pelton runners can be offered fully machined from a single forged block or as a casting solution.

Advantages of the Pelton 

• Minimum wear
• No cavitation damage 
• Limits Over-Pressure Effect over the penstock 
• Speed load control 
• High efficiency over wide flow range 

Gilkes Francis Turbines are available as either horizontal or vertical units, with a power output of up to 20MW and a head range or 30-400 Mtrs

Gilkes Francis model range includes 8 different specific speed designs. The Hydro team at Gilkes can advise on the best solution for your project. 

Advantages of the Francis 

• High efficiency 
• Suitable for a wide range of applications 
• Compact construction 
• Covers a wide head range 

Gilkes have a great deal of experience from single part replacement or upgrade to fully rehabilitating whole hydro installations back to their optimum working levels.

Modernization can improve the overall efficiency of your scheme. Increased generation and reduced downtime can provide improved annual energy production due to higher reliability and lower operator dependence. 

Optimizing components with updated technology can help you meet changing compliance regulations and offer plant safety improvement.

Gilkes has a range of turbines that can be optimized to a specific site to harness the potential energy of the water and turn it into electricity, utilizing either a reaction or impulse style of turbine. Where downstream pressure is required, or a turbine is fitted within a pressurized system, a Francis (reaction) turbine is the preferred choice. If the turbine can discharge to atmosphere, then a Gilkes Turgo or Pelton turbine can be installed. The Gilkes Turgo is ideally suited to and is often installed at the head of a water treatment facility where it can be utilized to control flow through the facility as well as generate power at the same time.

The electrical power that is produced by our turbines can be used in several different ways.

• The electricity can be used to power a water treatment/wastewater treatment facility to offset their annual energy consumption in a ‘behind the meter’ application
• The electricity can be sold directly in the grid with the means of a power purchase agreement
• If more power is produced than can be consumed, a combination of behind the meter and export to the grid can be achieved
• High Efficiency and Reliability
