VLT® AQUA Drives up to 315 kW can operate in ambient temperatures from -25 to 50 °C without derating.

The deragging functionality performs impeller washing cycles to extend manual maintenance intervals, maintain pump efficiency, and increase pump lifetime.

VLT® AQUA Drives 90 kW and larger come with 3C3 PCB coating as standard for long lifetime in harsh environments.

The central AAF solution can encompass up to 50 drives, keeping harmonic noise under 3% on all AC drives in the system.

The VLT® AQUA Drive supports cable lengths up to 150 m screened and 300 m unscreened.

VLT® AQUA Drives are available in a range of enclosures with protection ratings from IP00 to IP66.

VLT® Low Harmonic Drives provide a total harmonic current distortion (THDi) of a maximum of 5%.

Hot Swap technology combined with back-up master functionality ensures reliable, stable, and easy operation for cascade pump control, helping to avoid downtime.

The back-channel cooling system uses a unique heatsink design and heat pipes to conduct heat efficiently, exploiting heat differentials to cool electronics with minimal energy.

The integrated Smart Logic Controller functionality, a micro PLC, saves the need for investing in an external PLC and IO module.

Danfoss products are used across several key industries including HVAC, Food and Beverage, Packaging, Water and Wastewater, Refrigeration, and Marine applications. Their drives and automation solutions serve a wide range of applications such as pumps, fans, compressors, conveyors, process and material treatment equipment, mills, drums, kilns, winding/unwinding systems, drilling equipment, propulsion systems, winches, and power conversion for generation and smart grids. Danfoss has particular expertise in marine applications with over 40 years of experience, providing solutions for ship owner-operators, shipyards, system integrators, and OEMs.

Key features of Danfoss products include integrated design elements (harmonics, EMC design, DC choke, and EMC filter) that save installation time and panel space while improving reliability. Installation and setup features include removable terminals, USB ports for easy PC connection, application setup wizards, and optional memory modules for convenient parameter transfer. Safety and control features encompass integrated Safe Torque Off (STO) dual channel functionality, control algorithms that run both induction and PM motors, and integrated brake choppers for drives up to 22 kW. Additional operational benefits include side-by-side mounting without derating, operation up to 45°C without derating, and robust construction designed for maximum uptime and efficiency across various industrial applications.

Danfoss products offer various environmental protection ratings to meet different application requirements. Their VLT drive series are available in IP00 (Chassis), IP20 (Protected chassis), IP21 (NEMA Type 1), IP54 (NEMA Type 12), IP55, and IP66 (NEMA 4X) ratings. These ratings provide protection ranging from basic chassis protection to dust-tight and water-resistant enclosures suitable for both indoor and outdoor applications, with NEMA 4X/IP66 offering the highest level of protection against windblown dust, rain, splashing water, and external ice formation.

Danfoss offers an extensive range of accessories for their VLT® drive products, organized into several categories: Fieldbus options (including PROFIBUS, DeviceNet, CANopen, PROFINET, Ethernet/IP, and Modbus TCP communication cards), I/O and feedback options (such as general purpose I/O, encoder input, relay cards, and sensor input modules), safety options (including Safe PLC I/O and PTC thermistor cards), motion control options (position controllers and synchronizing controllers), power options (brake resistors and various filters), and other accessories like mounting kits, USB cables, and IP rating conversion kits. These accessories are designed to be installed in specific option slots (A, B, C, and D) on the drives to add extra features and tailor the drive to specific application needs.

Danfoss offers several main product lines including: Danfoss Drives (featuring VLT® and VACON® variable frequency drives, plus iC7 and iC2-Micro series), Industrial Automation solutions (sensors, switches, and fluid controls), Danfoss Semco firefighting systems, Sondex® Heat Exchangers, Hydronic Balancing and Control valves, Power Solutions (hydraulic components and PLUS+1® controllers), High Pressure Pumps for seawater applications, Industrial Refrigeration components, and Danfoss IXA emission gas measurement sensors.
