Upland Sites (Hillstreams)

 

SUMMARY

This page covers the product group consisting of vertical shaft square cased impulse turbines. The full range of heads (15 metres to 300 metres) and power outputs (1kW to over 1MW) are covered by ‘belt drive’ units. The use of direct drive or overhung designs will depend on the exact site conditions to obtain a synchronous speed. Each turbine can be built with different numbers of jets and a variety of runner sizes and types. The jets may be plain or controlled with a spear valve, and deflectors may be added to provide automatic shutdown.

In this ‘Product Gallery’ I am showing a selection of turbines that we have designed and built over the last 35 years. Most of the designs have been improved and up-rated and include enhanced features such as cast stainless steel runners, brushless alternators and our electronic control and governing systems. All have a 10 year guarantee and many have been operating continuously for over 30 years.

The prices given are for guidance only, because for any one turbine size there may be a range of alternators and control systems to match the required electrical output. This is why I give a BBS (basic bare-shaft price). To this price is added the drive, alternator and control system, together with any of the enhanced options such as spear-valves, actuators and deflectors. A basic system can be fully functional and as efficient as a more sophisticated unit, it is simply less convenient. Being modular, many of the enhanced options can be added at a later date if required.
