OJ-DVULHYour compact solution to harmonic distortion

The Ultra Low Harmonic drive comply with the strictest regulations and recommendations.

The drive you know. With distortion mitigation.
The tried-and-tested DV design has been adapted and enlarged to incorporate an active frontend. We’ve maintained the same connection and option module compartment, ensuring that your installation process is as easy as ever.

We’ve kept it very compact, too: compared to the standard DV drive, the Ultra Low Harmonic drive is just 8 cm longer and has slightly taller cooling ribs. All in all, its total size is just 25% larger in terms of volume (cm2) – while eliminating the need for separate filters.

Keeps sensitive equipment safe
OJ DV Ultra Low Harmonic is your ideal choice of drive for commercial HVAC applications with sensitive electronic equipment such as computers, telecommuni-cations networks and lighting. It fully meets the increasing demand for harmonic distortion protection at e.g. data centres, airports and hospitals – and of course, the unit complies with the strictest legal requirements. We created this to keep you, your business and your customers safe.
