Wastewater treatment solution provider KEE Process specified six large Flender gearboxes from Siemens Automation & Drives, for a prestigious project in Crynant, Wales.
Crynant is being supplied with six KEE Process rotating biological contactors (RBCs), which are modular treatment plants for medium and large-scale applications, part of a £3.3 million investment scheme by Welsh Water to upgrade treatment processes. The 4.5 metre, 6-bank RBCs are KEE’s largest UK application and have performed well since their switch-on.

Imtech Process carried out the installation, incorporating Flender FZG gear units combined with Motox units and Siemens eff1 motors. This design was selected to achieve high ratios for low speed operation (1 rpm output speed, 4kw power and 63,500Nm gearbox rating).
KEE Process’s contracts engineer Alastair McInnes said:
“Being driven by direct coupled geared motors, the units are virtually silent in operation. We selected the Flender-Siemens combination due to its reliability, low maintenance requirements, high torque and ongoing low power demands.”
