A pleasant atmosphere makes everyday-life more convenient and is natural to Lenze. Our know-how and our products for building automation, HVAC and environmental technology take care of this. The Global Drive 8200 vector frequency inverter mounted into the control cabinet or the 8200 motec mounted on the drive permit continuous speed control of fans and pumps. They are quiet, can be easily connected to host and fieldbus systems and offer a variety of monitoring options. The success is obvious: An optimum indoor atmosphere is achieved with only the actually required energy being consumed. As a result, energy consumption and operating costs can be clearly reduced.
