Otech Pivot Irrigation Systems – ST Range
Drawing on Otech’s 25 years of experience, performance, innovation, quality and standardisation, the Otech ST Range uses only first class components for reliability and longevity.
The range includes the ST Central Unit, ST Bibeam Tower and ST Tower. Structure is realised in high resistance steel S275 with a high carbon content and suited to a uniform galvanization.
Steel pipe is available in 3 or 4mm thicknesses.
Galvanized steel S275 overhang pipe is available in 6, 12, 18 and 24m lengths: a modular system allows a 12m pipe length to be substituted by two identical 6 m lengths for easy transportation.
Nozzles are computer calculated to ensure maximum distribution and uniformity.
