We have a switchboard construction section which is able to fabricate to order, or design and manufacture, high quality industrial switchboards at reasonable cost. This means we are able to fulfill a wide range of needs in process and motor control switchboards, using VF Drives and Soft Starters.
The use of PLC's, computer control and sensing of liquid levels, flow, temperature and pressure, enables us to contruct to order large current supply,distribution switchboards and high volume pump station switchboards.
