The Lock EWA 52.3505, model number 12528.3505.32, is a high-performance electric drive designed for automated ventilation and shading systems in greenhouses. With a torque of 350 Nm and a precise speed of 4.4 rpm, it reliably and smoothly moves even heavy loads.

Its self-locking double worm gear ensures secure position holding without the need for additional braking mechanisms—ideal for applications with high safety requirements. The robust We66 mounting form allows for stable installation, even in large-scale constructions.

Thanks to its IP55 protection rating, the drive is well protected against dust and moisture, making it suitable for continuous operation in greenhouse environments. The S3–40% duty cycle makes it ideal for cyclic motion sequences, such as those found in automated ventilation systems.

Note: This model replaces the EWA 14.3505 (12214.3505.66).
