The VLT® Refrigeration Drive FC 103 is designed to help significantly reduce the lifecycle costs of your refrigeration systems. It offers efficiency- and reliability-enhancing features, integrated process control functions and a commissioning environment specially designed to meet the needs of refrigeration applications. It also features a setup Wizard which uses common refrigeration terms. This makes installation and commissioning easy and safe for refrigeration technicians and installers.

The continuous variable speed control provided by the VLT Refrigeration Drive makes intelligent capacity control possible. By creating stability while balancing the capacity to the actual load, system-wide coefficient of performance improves providing significant energy savings in a wide range of applications.

The drive contains all modules necessary for compliance with EMC standards. The integrated, scalable RFI filter minimizes electromagnetic interference, and the integral DC link chokes reduce harmonic distortion in the mains network. As these features are built in to the drive in the factory, cabinet space can be reduced. Efficient EMC mitigation also enables the use of cables with small cross sections which reduces installation costs.
