Bitzer offers digital support for using its Varipack frequency inverters

Bitzer has published a video explaining how to design, configure and commission its Varipack frequency inverters, the company said through a Press communiqué. The video can be found on the YouTube video platform and offers valuable assistance when it comes to using the external frequency inverters.

The video shows Bitzer employees designing a Varipack frequency inverter for the requirements of a refrigeration system with Bitzer compressor. There are two versions to choose from, with the required steps explained in English or German. Users also require the Bitzer software, BEST (Bitzer Electronics Service Tool) and a BEST interface converter or an Ethernet cable. The two software tools are available free of charge on the Bitzer website, the company said. Once the Varipack has been installed and wired as recommended, it can be commissioned and configured, the company added.

According to Bitzer, in combination with its reciprocating compressor, the Varipack frequency inverters belong to its IQ product range and offer an intuitive commissioning process that doesn’t require any specific knowledge about frequency inverters. Its advantage is that it adjusts to ideally suit the system’s current cooling demand, reducing both energy consumption and running costs, the company said. The precise coordination of compressor and frequency inverter saves additional energy and thus increases compressor efficiency in full and part-load, the company added. The external Varipack frequency inverters are also designed for modern motor concepts, including the permanent-magnet motors of the Bitzer Ecoline+ reciprocating compressors and other motors modified specifically for frequency inverters, the company further added.
