OJ-DC SeriesOJ-DC is a series of Frequency Converters dedicated for Compressors

This new series of drives is dedicated to compressor systems comprising 5 output variants (from 4 to 15kW) fitted in 2 different enclosures to match scroll compressors for chillers and AHUs.

Robust and built to last
With a durable aluminium enclosure, the DC series can continuously operate in almost any environment from -40°C to +50°C / -40°F to +122°F.

Energy efficient
The OJ DC drives save energy while providing reliable, highly efficient power for the compressor. With OJ DC, there will be efficiency of up to 97%.
