Superior performance for maximum results

Energy saving heat management

Energy saving heat management

A unique back-channel cooling concept transfers up to 90% of heat away from the room, using a fan-less design that exploits heat differentials in materials and air temperature and the latest developments in heat piping technology.

Our back-channel cooling system offers up to 90% reduction in your investment for air cooling systems to remove heat from the drives.

Integrated condition-based monitoring (CBM)

Integrated condition-based monitoring

Take motor and pump supervision to new levels with the intelligent VLT® AQUA drive.

Integrated condition-based monitoring lets you react quickly to critical situations like clogging, leaks, motor winding failure, vibration wear, mechanical misalignments and  wear-out.

Cloud-free artificial intelligence embedded in the drive automatically defines operating baseline parameters corresponding to specific applications, at all speeds and real-life operating cycles. Reduced installation time and predictive maintenance lower operating costs and boost uptime.

    Breaking the Pump Clog Cycle with Danfoss VFDs and Built-in Deragging

    The Grand Strand Water and Sewer Authority in Myrtle Beach, South Carolina was struggling to keep up with demand at one of its main sewage pressure reducing stations. Myrtle Beach, a popular tourist destination, uses approximately 15 million gallons of water per day (MGD) or 5.5 billion gallons of water per year. The South Regional Pressure Reducing Station handles approximately 3 MGD and is controlled by suction pressure and a PID (proportional-integral-derivative) loop.  Its purpose is to reduce pressure on the south side of the sewer district to enable the other stations to pump more.

    Keeping the Water Flowing with the VLT® AQUA Drive FC 202

    In early 2023, the Warren County Utility District (WCUD) in middle Tennessee was faced with a dilemma. The water tank in their Short Mountain (SM) pressure zone required cleaning and repairs as part of federal compliance regulations, but with only one tank in the pressure zone, as is the case with many rural municipalities, they had few options to maintain water service to customers while the tank was out of service during the washout process and while repairs were completed. WCUD maintains a 4.0 MGD Water Treatment Plant, six storage tanks, four remote pump stations, into four pressure zones with approximately 650 miles of mains to serve 9,000 customers in rural portions of Warren and five adjacent counties.

    Hospital selects DrivePro® programs to keep costs down, maintain efficiency

    As the largest regional medical center in San Joaquin County, St. Joseph’s Medical Center in Stockton, Calif., has 359-beds, employs over 400 physicians and more than 2,400 employees. Operating the HVAC mechanical equipment for a facility this large is a huge energy-conservation challenge. That's why St. Joseph’s made the decision to use variable frequency drives (VFDs) on HVAC pump and fan motors —a decision that continues to pay off today, thanks to an innovative upgrade plan using Danfoss VLT® Drives.
