Summary
Use a 3-phase, 5-wire system (L1, L2, L3, N, G) for standard three-phase dehumidifiers.
No neutral available? We can build a dehumidifier that works without it.
Compatible with both 380V/50Hz and 460V/60Hz power systems.
In industrial and commercial settings, dehumidifiers often rely on three-phase power for efficient and stable operation. Three-phase systems are known for their ability to deliver more consistent power, lower current per phase, and reduced energy loss compared to single-phase alternatives. This makes them particularly suitable for heavy-duty equipment, including high-capacity dehumidifiers.
However, when it comes to powering a dehumidifier with three-phase electricity, there’s an important technical detail you need to be aware of.
The Advantage of Three-Phase Power in Dehumidifiers
Industrial dehumidifiers often feature three-phase compressors and fans, which run more efficiently and reliably when connected directly to a three-phase supply. Since these components don’t require a neutral wire, a three-phase connection without a neutral may seem sufficient. But that’s not the whole story.
Why Your Three-Phase Dehumidifier Still Needs a Neutral Wire
While the main motor components may operate without a neutral, the control circuits, protection systems, and electronic displays inside the dehumidifier typically require a single-phase supply. This is why we strongly recommend using a three-phase, five-wire system (L1, L2, L3, Neutral, and Ground) to ensure the unit operates safely and correctly.
We Can Customize a Solution for Your Needs
What if your facility only has a three-phase supply without a neutral? No problem. Just let us know in advance, and we can customize a three-phase dehumidifier that operates without a neutral connection.
Additionally, whether your power supply is 380V/50Hz or 460V/60Hz, our equipment can be designed to match your voltage and frequency requirements.
Choose reliability. Choose compatibility. Let us provide the right dehumidification solution for your industrial environment.
