Optimize comfort and energy consumption in building ventilation
With user-friendly interfaces, distributed intelligence and reduced power consumption, Danfoss AC drives optimize the performance of fans.
The VLT® HVAC Drive and VLT® Refrigeration Drive convert velocity pressure sensor values into flow values, enabling setup based on fixed flow or fixed differential flow. This optimizes both comfort and energy consumption. To improve comfort levels even further, drives connected to fans can be set to avoid the frequency bands which create resonance and damage in the ventilation system.
Extended building management system capacity
When integrated into a building management system network, to extend the capacity of the controller, all HVAC drive I/O points are available as remote I/Os. For example, room temperature sensors (Pt1000/Ni1000) can be directly connected to the system.
Improved air-handling performance
The VLT HVAC Drive and VLT Refrigeration Drive are fitted with a built-in Smart Logic Controller and four auto-tune PID controllers to control air-handling functions with fans, valves and dampers. The direct digital controllers of the building management system are released and valuable data points are saved lowering air-handling costs.
The VLT HVAC Drive handles logical rules and input from sensors, real-time functionality, and time-related actions. This enables the AC drive to better control a wide range of functions:
Reliable harmonic mitigation
While AC drives increase precision, save energy and extend application lifetime, they also introduce harmonic currents to the grid. If not kept under control, harmonic currents can affect the performance and reliability of generators and other equipment.

EC+ Concept
When building an HVAC system, to get the highest performance and system efficiency, the individual components – motor, drive and fan – need to be flexible and broadly compatible with each other. For instance, if you specify a high-efficiency motor that is only compatible with lower efficiency fans, the overall system efficiency would suffer and would not reflect the high performance – and investment – in the individual components.
Danfoss Drives’ EC+ concept allows ventilation system designers to combine a VLT® HVAC Drive with the most efficient fan and high-efficiency permanent-magnet or synchronous reluctance motor.
Advantages of the EC+ concept
FC 103 is dedicated to controlling compressors, pumps and fans for significant energy savings in refrigeration plants.
This tough and savvy FC102 drive enhances pump and fan applications in building management systems, and runs outdoors in most climates.

Airports globally have evolved from just being docking stations for the flights to becoming an avenue that houses the best experiences a traveler can get. From retail stores to restaurants, from lounges to culture showcase centers, every new airport today is pushing the standard on experiences. But, delivering these uber experiences alongside a thermal comfort inside the airport expends a lot of energy. With close to 100 million passengers travelling through domestic routes every day in India[1] and with the number exponentially increasing, curating a comfortable experience for the guests can be a challenge.
