Danfoss Drives VLT® HVAC Drive FC 102 and VLT® HVAC Basic Drive FC 101 are designed to keep your HVAC systems operating reliably and efficiently, even in the middle of another blazing heatwave! Bag your Danfoss HVAC Drives from LED Controls today.

Why use Danfoss HVAC Drives?

Rather than continuously running a fan or pump motor at full speed, an HVAC Drive can adjust motor speed according to actual system demand. This reduces your system's energy consumption while maintaining the airflow, pressure or cooling required by the building. Danfoss HVAC Drives are suited for applications including:

  • Air handling units
  • Supply and extract fans
  • Fan walls
  • Pumps
  • Chillers and cooling systems
  • Rooftop units
  • Smoke extraction and ventilation systems

Danfoss VLT® HVAC Drive FC 102

The Danfoss FC102 is a dedicated HVAC drive combining efficient motor control with intelligent functions developed specifically for building services. It supports induction, permanent magnet and synchronous reluctance motors, giving you plenty of options when selecting high-efficiency motor technology.

For fan applications, the FC102 includes speed bypass to prevent operation at mechanical resonance frequencies, while broken-belt and no-load monitoring provide early warning of potential problems. The FC102 can also operate multiple induction motors in appropriately designed fan-wall applications.

A built-in Smart Logic Controller and four PID controllers can manage variables such as airflow, pressure and temperature, keeping need for additional control equipment to a minimum.

Monitor HVAC performance before problems develop

When outside temperatures are high, an unexpected HVAC failure can turn your facility into an oven. The FC102's integrated condition-based monitoring capabilities can keep an eye on your application and spot early indicators of anything going awry.

Unusual vibrations, abnormal motor conditions or changes in the application's load profile can trigger the CBM alert before an unexpected shutdown, meaning less reactive and more preventative maintenance.

Connect directly to your Building Management System

The Danfoss FC102's Industrial Communication Protocol options include BACnet, BACnet/IP, Modbus TCP, PROFINET, EtherNet/IP and PROFIBUS, allowing drive and application information to be integrated seamlessly into your wider Building Management System (BMS). For air handling units, the drive can also work directly with sensors, fans, dampers and valves, creating an intelligent and flexible HVAC control solution.

What about the Danfoss FC101?

The Danfoss VLT® HVAC Basic Drive FC 101 provides a more compact and economical solution for straightforward control of HVAC fans, pumps and compressors. The FC101 supports induction and permanent magnet motors and includes dedicated HVAC functionality and Danfoss Automatic Energy Optimisation technology.
