Wide ambient temperature range

The robust OJ DV are capable of continuous operation from -40° to +50°. At higher temperatures, the drive will continue operation with lower performance.

In fire mode, the OJ DV overrides the drive’s self-protecting features and can run for one hour in temperatures up to +70° degrees. This means that the OJ DV can be used for smoke extraction; you will not need to install a separate system for that.

Energy efficiency

OJ Drives operate at up to 97% efficiency. Mount them inside the airflow to achieve full efficiency.
