The Danfoss 134F9155 is a reliable and efficient AC variable frequency drive (VFD) designed for refrigeration, compressor, pump and fan applications. As part of the advanced Danfoss VLT® Refrigeration Drive FC 103 series, it is engineered to optimise energy use, improve motor control and extend the operating life of refrigeration system components.
This drive provides precise speed regulation for demanding refrigeration and HVAC environments. The FC 103 platform is specifically developed for refrigeration systems, offering application-focused functionality that supports stable operation, reduced mechanical stress and improved system efficiency across variable load conditions.
With a rated output power of 18.5 kW (25 HP) and a three-phase 380–480 V AC input supply, the Danfoss 134F9155 is ideal for compressors, condenser fans, evaporator fans, pumps and industrial refrigeration equipment. Its IP21 / Type 1 backplate enclosure is suitable for protected indoor cabinet or panel-mounted installations.
The Danfoss VLT® Refrigeration Drive FC 103 is designed to support efficient operation of refrigeration systems by matching motor speed to real cooling demand. This helps reduce energy consumption, improve temperature stability and lower mechanical stress on compressors, fans and pumps.
By using variable speed control instead of fixed-speed operation, the Danfoss 134F9155 helps refrigeration equipment operate more smoothly and efficiently. Its integrated filtering, IP21 backplate enclosure and graphical control interface make it a practical choice for professional refrigeration engineers and industrial maintenance teams.
