Freely configurable and virtually silent: at up to 1800 N, the LD Series opens and closes even the heaviest louvre windows quietly and reliably. In addition to this standard version, the LDx-1-PLP is also available in an “fail-safe version”.

Max. force of pressure and tensile force of 1400 N and 1800 N
Holding force of 5000 N for very large louvre windows
Louvre window drive can be adapted for all common louvre manufacturers (such as EuroLam, Fieger, HAHN, NACO, Schneider + Nölke)
Centrally supported driver position
Developed based on DIN EN 12101-2
D+H LDx-1-PLP can be used for openings for smoke exhaust and for daily ventilation
With motor electronics controlled via microprocessor
With a sound pressure level of LpA ≤ 45 dB(A), the drive is among the quietest of its class
Corrosion‑protected drive components
Programmable drive functions and different drive parameters
Additional passive and active anti‑trap protection system for the main closing edges with reversing function
A fail-safe version of the LDx drive is available, which guarantees opening and closing in the event of a power cut, the function is secured by an energy storage (LDx-1-PLP-FS). The technical data and dimensions of the fail-safe version is different from the LDx-1-PLP version, for more information about the fail-safe product please contact us.
