Liquid-Cooled VFD Cabinet 75–1386 A
This liquid-cooled variable frequency drive (VFD) cabinet covers 75–1386 A on three-phase 380 V with V/f and vector control and IP21 / IP54 protection. It cools by direct liquid cooling or internal-external dual-loop heat exchange, removing drive heat from the machine room without large air handlers.

Product Description
In noise-sensitive or space-constrained plants, moving drive heat by air means big ducts and big fans. This cabinet takes the heat out by liquid instead: direct liquid cooling, or an internal-external dual-loop heat-exchange design that needs an external liquid source but keeps the electronics sealed. Ratings span 75 A to 1386 A at 380 V, with a 75–1000 kW water-cooled configuration also available.
V/f and vector control drive asynchronous and synchronous motors, IP21 / IP54 options match the mounting environment, and AFE active front-end or APF active-filter modules handle harmonic requirements. The result is a drive room that is quieter, tighter and easier to cool than an air-cooled equivalent.

FAQ about Liquid-cooled VFD
Why choose liquid cooling for a VFD room?
Liquid cooling removes heat at the source, so the room needs far less ventilation air. That cuts air-conditioning load, lowers noise, and lets the drives sit closer to the machines they run — useful on ships, in basements and in retrofit machine rooms.
Does the dual-loop version need a chiller?
The internal-external dual-loop design requires an external liquid source for the outer loop; the direct-liquid version connects to the plant's cooling circuit. Tell us which liquid source is available and we propose the matching configuration within 24 hours.
