Voltage is a specification, not an afterthought
A compressor ordered for the wrong supply is not a small problem. Motors run hot or slow, contactors chatter, controllers fault, and the fix usually means a new motor and control transformer in the field. The supply has to be confirmed before the build starts, not after the container lands.
| Configuration | Typical market |
|---|---|
| 380 V / 50 Hz / 3 phase | China, most of Europe, Middle East, Southeast Asia |
| 400 V / 50 Hz / 3 phase | Continental Europe |
| 415 V / 50 Hz / 3 phase | India, parts of the Middle East and Africa |
| 220 V / 60 Hz / 3 phase | Parts of Latin America |
| 380 V / 60 Hz / 3 phase | Brazil, parts of Latin America |
| 440 V / 60 Hz / 3 phase | North America industrial, export projects |
What we need from the buyer
- Site voltage, phase and frequency, taken from the actual supply, not from a catalogue description of the country.
- Whether the supply is stable, or backed by a generator whose frequency may drift.
- Ambient conditions at site, particularly where the compressor room exceeds 45 degrees C.
- Any local requirement on the control panel, marking or documentation.
Beyond voltage
Colour, panel design, logo and configuration are all customisable for OEM and distributor projects, including mixed orders where the same machine model ships in different voltages to different markets. That is normally handled as separate build batches rather than field conversion.
Why this matters for a catalogue programme
Export buyers comparing models across suppliers are often comparing machines that cannot be connected to their supply at all. Confirming voltage and frequency early removes the most common cause of a deal collapsing at the installation stage.
