Save energy and extend the lifetime of refrigeration applications

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.

Supply voltages and power range

3 x 200-240 V…1.1-45 kW
3 x 380-480 V…1.1-560 kW
3 x 525-600 V…1.1-7.5 kW
3 x 525-690 V…75-800 kW

Features and benefits

Energy consumption and maintenance requirements are reduced thanks to a range of pump features such as the pump cascade controller and flow compensation
Optimum system efficiency is achieved by taking advantage of the drive’s software features
Challenging environments are no problem due to the drive’s coated electronics
The need for external cooling or oversizing is avoided as the drive operates efficiently in a maximum ambient temperature of 50°C without derating
There are no EMC concerns as a result of integrated DC link harmonic and EMC filters

Features and benefits	– Assets are protected thanks to specially designed software that prevents, for example, water hammering – Energy efficiency is maximized as a result of the drives control algorithms and design which focus on reducing heat loss – High energy savings related to air conditioning are ensured due to the unique back-channel-cooling concept that transfers 90% of heat away from the room – Electromagnetic interference and harmonic distortion are reduced thanks to the built-in, scalable RFI filter and integrated DC link chokes – Perfect system integration and adaptation to the application are possible due to freely programmable warnings and alerts 3–8% energy savings are achieved as a result of Automatic Energy Optimization
Applications	Centrifugal pumps and blowers, positive displacement blowers.
