High Quality, Very competitive by design to:-
IEC 61439-1&2 (2009)
(BS EN 61439-1:2009 & BS EN 61439-2:2009)
For many years Rolla have been supplying the system/panel building industry with High Quality Motor Control Centres, many of which are an important part of the UK Water Companies Framework Agreements.
With cost savings firmly in mind we have drawn on our experience in this market sector and developed the new Utility Control Centre.
This highly competitive Motor Control Centre incorporates all the requirements of the water industry while maintaining the high quality of build that Rolla is renowned for.
