2026 | 05 Open slowly– close fast: SpeedLogic! SpeedLogic drives are suitable for situations where drive units close at up to three times normal speed on all kinds of ventilation and screening applications. The combination of EWA 50, 52, 56 power drive and SPL frequency inverter makes speeds of up to 15 revolutions per minute (rpm) possible – pre-configured in stages in a user-friendly manner. The frequency inverter makes it possible to dispense with the need for a reversing contactor control unit. Example: EWA 52 + SPL 60 Frank Lock // CEO “As a pioneer in the ventilation and screening sector, we are committed to the topic of innovation in all areas. The connection or interface between mechanical and electronic systems occupies a central position here. This is a great challenge because of the particular conditions governing animal shed and horticultural construction environments.” CHAPTER 04 – LOCKLOGIC® LockLogic® 3
