Kee buys six Flender gearboxes for Welsh project

Kee Process has bought six of the largest Flender gearboxes it has ever ordered, from Siemens Automation and Drives, for a project in Wales.

The company supplied six Kee Process rotating biological contactors (RBCs), modular treatment plants for medium and large-scale applications, to Crynant, a small village in the Neath Valley.

The contactors will form part of a GBP3.3m investment by Dand#373;r Cymru Welsh Water to upgrade its treatment processes.

The 4.5M, six-bank RBCs are Kee's largest UK application and have been performing well since their switch-on in December 2007.

Imtech Process installed the Kee units, which incorporated Flender FZG gear units (size H3DH11), Motox units (size KAF108K4-1LA9) and Siemens eff1 motors (size 113-4KA).

This combination drive design achieves high ratios for low speed operation (around 1 rpm output speed, with 4kw power and 63,500Nm gearbox rating).

Alastair McInnes, contracts engineer for Kee Process, said: 'Due to 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.' Dand#373;r Cymru Welsh Water is investing GBP1.2bn in its water and sewerage network between 2005 and 2010.
