Extra protection for use in marine and heavy industries

VACON® NXP Liquid Cooled drives are integrated in a sturdy enclosure making them ideal for a wide range of industries with harsh operating conditions.

Liquid-cooled AC drives can be used in many combinations, from a single dedicated frequency converter to large-scale common DC bus systems. Packed with features, these fully standardized enclosed drives maximize the utilization of space while minimizing overall lifecycle costs.

Thanks to the high degree of protection (IP54), these drives can be installed almost anywhere in a plant or on a vessel. This eliminates the load on air-conditioning systems in electrical rooms reducing costs and installation time, and makes them ideal for retrofitting.

Servicing is fast and easy. Features such as safe torque off (STO) and safe stop 1 (SS1) improve safety, and conformal coated circuit boards enhance reliability.

NXA, NXN, NXB and NXI configurations
Active Front-end (NXA), Non-regenerative Front-end (NXN), Brake Chopper (NXB) and Inverter (NXI) configurations are available.
For more information about these configurations please refer to the VACON® NXP Common DC Bus selection guide.

Power range

3 x 400-500 V...700-1100 kW
3 x 525-690 V...800-1550 kW

Features and benefits

Drive lifetime and reliability are enhanced due to sturdy cabinet protection

Floor space requirements and infrastructure needs are reduced as the compact design needs no air ducts

Investment savings as no large air-conditioning systems are needed due to minimal dissipation of heat loss to the air

Fulfills all relevant international standards and global requirements including marine, safety, EMC and harmonics approvals

Virtually silent operation as no large cooling fans are needed
