VFD Repair in Rayong, Thailand

Thailand repair centre

Regional and multinational plants can send a VFD to the Rayong repair centre. The centre inspects the unit, then confirms the work scope.

We do not repair every model or brand. We only take on work we can do well. Brand and model names are used only to identify equipment and do not imply any agency or manufacturer certification.

• —Send the brand and the complete model number from the nameplate before dispatch.
• —A model that has not been assessed is not accepted from the name alone.
• —Price and lead time are given after inspection of the actual unit.

What to prepare before sending a unit

1. 01A clear nameplate photograph showing the brand and the complete model number.
2. 02Photographs of the display and the fault code exactly as shown.
3. 03A description of the symptoms and when they occur, such as during startup, under load, or after a power dip.
4. 04External photographs and any known repair or component-replacement history.

Remove unrelated customer information from photographs before sending them.

How send-in repair works

1. 01Contact the centre by phone or email with the information above. The primary phone is +66 88 660 6999.
2. 02The information supports an initial assessment.
3. 03After the unit arrives, the centre opens it and inspects its actual condition.
4. 04The work scope, price and lead time are confirmed after that inspection.

The repair centre has a high-power back-to-back motor test setup. Test scope depends on the model and the condition of each unit.

Published Indonesia nickel-project record

A published Indonesia nickel-project record remains on the case studies page. Two DUCHENG engineers calibrated parameters, ran performance tests and inspected operating risk so that first ignition could proceed on schedule.

That record is commissioning support at the project site. It is not a diagnosis of any other unit, and it is not a guarantee of the result for a unit sent to Rayong.
