User-friendliness, distributed intelligence and reduced power consumption are all key in fan applications. The VLT® HVAC Drive FC 131 delivers on all of these parameters and is able to control a wide range of functions. These functions have been developed in close cooperation with OEMs, contractors and manufacturers around the world to tailor them to your exact needs.
In the event of fire in a building, the Fire Emergency Mode safety feature prevents the drive from stopping to protect itself. Instead, it will continue vital fan operation to secure optimal smoke extraction or over-pressure in the stairwell to ensure occupants can more safely evacuate buildings via staircases.
The VLT® HVAC Drive also features a Multi-zone Fire-mode function that allows for adjustable speed controls depending on the zone(s) where the fire is active. Utilizing the logic within the drive allows for a less complex and more reliable smoke extraction system that can respond to multiple zones according to need.
The VLT® HVAC Drive FC 131 is a compact and competitive drive for essential HVAC applications. Read our Fact Sheet to learn more.

EC+ concept is based on high-efficiency PM motors combined with drives running the VVC+ control algorithm for optimal system efficiency.
An EC+ concept system normally offers higher efficiency, since axial fans consume much less energy, and generate a higher air throughput than EC fans. Furthermore, the design of these PM motors is based on the IEC standard for motor mechanical construction – making it easier to upgrade an existing system.
