A drives programme dedicated to ventilation solutions

OJ Electronics have more than 50 years of experience in the HVAC business and have developed drives for the ventilation segment for more than 20 years. The combination of our high product quality and our extensive  ventilation application know-how have resulted in a dependable drive.

Our range of OJ DV drives comprises 13 output variants (from 0.5 to 15 kW) fitted inside five different housings to match any rooftop fan, plug fan, or AHU application.

NEWS: OJ Drives now available in single-phase power up to size 1.3 kW
Our OJ DV product range has been extended with a thirteenth  variant in the single-phase supply range.  The new OJ DV-1013 has a larger housing than the existing H1 variant. This enables placement outside the airflow, thereby making installation very flexible. The unit is self-cooling: its large cooling ribs ensure sufficient cooling without the need of airflow through the ribs, which means that  you get 1,300 W shaft power up to ambient temperatures of  +40˚C.  Read more about the latest addition here.



Continuous operation from -40° to    + 50°. In Fire Mode, the drives can run for one hour at 70°.



Knowledgeable dialogue and close cooperation is the shortest route to a perfect solution.



OJ Drives are designed to make complex operations become effortlessly simple.
