Get even more drive in your HVAC – with rock-bottom lifecycle costs in any climate

More than ever, the extreme climates, inaccessible machine rooms and isolated outposts of our planet need the best process control there is for their HVAC installations. Your everyday critical functions and costly systems need it too, as they face ever-increasing competition and efficiency demands. Always with high performance in mind, the enhanced VLT® HVAC Drive gives you more room to maneuver. It confronts the issues and gives you rock-solid reliability. With rock-bottom lifecycle costs too.

The AHRI Certified™ VLT® HVAC Drive is designed to bring optimized process control to all heating, ventilation and air conditioning (HVAC) applications. Easy to use and with built-in intelligence, the drive is fast and cost-effective to commission. It features a wide range of functions specifically developed for use with pumps, fans, and compressors to save energy, meet environmental regulations and reduce costs in modern buildings.

The compact design of the VLT® HVAC Drive and its efficient heat management system mean it is ideal for applications where drive space is restricted.  A selection of safety features, such as Safe Torque Off and Safe Maximum Speed, protect both applications and their operators.

Maximum uptime is ensured as this robust drive offers problem-free operation in harsh environments. Enclosures are available up to IP 66 (depending on the model). And a special coating is available as an option to provide extra protection for circuit boards. Integrated DC chokes and RFI filters safeguard installations by minimizing harmonic distortion and electromagnetic interference.

Features and benefits

  • Slim down your total cost of ownership (TCO) with optimal energy control and usage, low maintenance costs, and minimum 10 year designed operational lifetime with no component replacements 

  • Intelligence built-in with pre-programmed HVAC control and monitoring features 

  • Maximize uptime. Integrated condition-based monitoring (CBM) detects system changes early to enable preventive action, such as operational corrections to avoid cavitation in pumps. 

  • Cybersecurity is integrated, with user role restrictions to access important information. Complies with Cyber Resilience Act IEC 62344-4-1 and -2, level SL1. TÜV-certified in Germany 

  • Simple installation in outdoor conditions. Reliable performance in extreme climates and ambient temperature -25ºC to +55ºC. Ruggedized enclosure 

  • Wide power range and extensive enclosure program, to match any application and installation need 

  • Easy to use with familiar user interface in 27 languages. Fast commissioning thanks to the SmartStart program 

Avoid unplanned downtime with condition based monitoring

Unplanned downtime of HVAC systems can be catastrophic for essential infrastructure and those who depend on it today. Danfoss technologies empower frontline operators - both on site and remote - to predict unforeseen early failures thereby better planning for maintenance and maximizing uptime. Explore how intelligent VLT® drives solve potentially critical problems in HVAC applications.
