DANFOSS VLT FC100 HVAC Drive

• Optimising energy consumption in commercial and industrial building HVAC systems.
• Controlling the speed and torque of pumps in heating and cooling circuits.
• Managing fan speeds in air handling units and ventilation systems.
• Regulating compressors in chiller and refrigeration plants.
• Integrating with building management systems (BMS) for centralised control.

Typical power range

For this class of equipment, units commonly range from 1.1 kW to 400 kW, with specific models extending beyond this.

Power supply

Typically available in 3-phase configurations, commonly 380-480V, though single-phase options may exist for lower power ratings.

Motor control principle

Units of this type commonly employ VVC+ (Voltage Vector Control) or U/f (Volts per Hertz) control for efficient motor operation.

Enclosure rating

Commonly available with IP20 (panel mount) or IP54 (wall mount) ratings, offering varying levels of protection against dust and moisture.

Communication protocols

Typically supports standard industrial protocols such as Modbus RTU, BACnet, or LonWorks for integration into control networks.

Operating temperature

Units are generally designed for ambient temperatures ranging from -10°C to +50°C, with potential derating at higher temperatures.

• What is a VLT FC100 HVAC Drive?

  The VLT FC100 HVAC Drive is a variable frequency drive (VFD) specifically engineered for controlling motors in heating, ventilation, and air conditioning applications. It optimises motor speed to match demand, leading to energy savings.

• What are the main benefits of using an HVAC drive?

• Can this drive be integrated with existing building management systems (BMS)?

• Is specialist knowledge required for commissioning?

• What maintenance is typically required for an HVAC drive?

HVAC drives and controllers are valued for reliable temperature and humidity regulation in controlled laboratory environments. Buyers typically prioritise units with precise calibration history and minimal downtime records. When purchasing used equipment, inspecting control boards, sensor functionality and documentation of maintenance schedules proves essential. These systems gain strong reputation for durability when properly serviced, though older models may lack advanced digital interfaces. Compatibility with existing facility infrastructure remains a common purchasing consideration.
