VLT® HVAC Drive FC 131 - competitive and compact

Essential fan and pump installations call for intelligent solutions

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.

Intelligence for fire & emergency operation

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.

Danfoss EC+ Concept

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.
