The Danfoss 131B8138 is a compact and efficient HVAC variable frequency drive (VFD) designed for precise speed control of three-phase motors in heating, ventilation, air conditioning and refrigeration systems. As part of the trusted Danfoss VLT® HVAC Drive FC 102 series, it is engineered for HVAC applications requiring reliable motor control, energy efficiency and straightforward integration into building services systems.
This drive helps optimise HVAC performance by adjusting motor speed to match actual system demand, reducing unnecessary energy use while improving equipment reliability and service life. The FC 102 platform includes dedicated HVAC functionality, intelligent control features and practical commissioning tools for building services engineers, contractors and system integrators.
With a rated output power of 4.0 kW and a three-phase 380–480 V AC supply, the Danfoss 131B8138 is ideal for HVAC pumps, fans, air handling units and refrigeration equipment. Its IP20 / chassis enclosure and compact A2 frame make it suitable for installation inside electrical control panels and HVAC cabinets.
The Danfoss FC 102 HVAC Drive regulates motor speed by adjusting output voltage and frequency, allowing connected HVAC equipment to operate according to actual demand rather than at fixed speed. This helps reduce energy consumption, lower mechanical stress and improve the reliability of motors, fans, pumps and compressors.
Designed specifically for heating, ventilation and refrigeration applications, the FC 102 series provides dependable performance in commercial buildings, industrial facilities and plant rooms. Its integrated EMC filtering, Safe Stop function and graphical control panel make it a practical choice for modern HVAC installations requiring efficient motor control.
