The LCX9000 Liquid Cooled Drive family continues Eaton's tradition of providing state-of-the-industry products, by taking advantage of liquid cooling technology in lieu of air-cooling techniques. The LCX9000 drives are liquid-cooled products that utilize potable water or a water-glycol mixture as a cooling medium.

Product Range

• 380 - 500V, 10 - 1800 Hp
• 525 - 690V, 200 - 2000 Hp

The liquid-cooled LCX9000 Drive is our most space-saving AC drive, well suited for locations where air-cooling would be difficult or expensive, or where the installation space is at a premium. As no air channels are required, the drives are extremely compact and suitable for ships and in the offshore industry, in mines or in the heavy industry. As almost all of the heat generated is removed in the coolant, a high degree of protection is easily achieved at all power ratings. The space savings compared to just the power module of a similarly rated air-cooled drive can be up to 70%. The liquid-cooled drives are built around the hardware and software modularity concept used through out the LCX9000 range. The liquid-cooled drives have a power section designed from the start for liquid cooling, contrasting with the more usual way of just replacing an air-cooledcooling element with a liquid cooled one. This design has allowed a great reduction in size.
