With one of the best power/size ratios, VACON® NXP Liquid Cooled drives are ideal for applications where space is at a premium or air cooling is difficult. Heavy industries with harsh operating conditions, such as in marine, offshore and mining environments benefit from the drive’s compact design and robust reliability.
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 drives maximize the utilization of space while minimizing overall lifecycle costs.
As a high degree of protection (IP54 or higher) can easily be achieved with these drives, they 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.
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.
Enclosure sizes CH3 and CH4 have reached the Limited phase of their lifecycle and were discontinued in 2021. In this phase, Danfoss offers assistance using services such as DrivePro® Spare Parts, DrivePro® Retrofit, and in some cases, DrivePro® Preventive Maintenance.
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 large cooling fans are not needed
Compressors, wind turbines, extruders, pumps, fans, conveyors, crushers, thrusters, and propulsion, test-bench, crane, winch and power-conversion systems.
By controlling industrial pumps with a Danfoss AC drive you can help optimize processes and significantly reduce energy and maintenance costs.
Draw upon expertise from Danfoss to optimize energy storage solutions using drives for power conversion both on board vessels, and in shore power supply for quieter and cleaner harbors.
For more efficient operation and greater freedom in ship design, consider an electric-based main propulsion with engineering from Danfoss.
For reliable operation, reduced emissions, and long life of marine pumps and separators, draw upon engineering knowhow from Danfoss.
Variable speed control of screw, reciprocating and scroll compressors gives you typically 15% reduction in energy consumption, and higher COP at part loads.
By running winches and cranes on an electric motor you can achieve energy savings, low noise operation and no risk of hydraulic oil overheating or leaks.
