Acvatix Series

The large rotary and
linear actuators SAL and SAX
Linear actuator with
cooling bracket and
quick connector
The tidy
layer with a
plug-in module
Simple, free from play and safe
mounting with the quick connector
Identifying the operating status
from a distance explicitly,
regardless of the mounting sense

The Acvatix actuators were custom tailored to planners' and installers' needs.

All rotary and linear actuators have — for cost efficiency — a uniform platform core, in addition to standardized mounting, operation and maintenance. The housing construction and cable guide improve accessibility and safety. The actuator is easily adjusted — for installation, service or in case of emergency — by means of a handwheel. No tools required.

Analysis of involved parties with their needs and interrelations. Users, influencers, decision makers.
