NENUTEC spring return damper actuators are
especially designed and produced for applications in
the HVAC systems.
■
Our wide range of NENUTEC spring return damper
actuators has been developed to operate and position
air dampers of different sizes that perform safety
functions. Angular positioning of modulating actuators
can be controlled by the NPG-1 positioner.

OEM Customised Version on Request
TELIMA offers you NENUTEC actuators in customised versions, e.g. with your own brand name, with colour-coordinated applications
and with your particular demand. Please contact us for further information.
Important Remark
Consult NENUTEC representatives for specific requirements and material selections for your intended application.
This actuator includes electrical and electronic components and may not be disposed as household garbage. Please consider the local valid legislation.
AC / DC 24 V: Connect via safety isolating transformer.
AC 230 V:
To isolate from the main power supply, the system must incorporate a device which disconnects the phase conductor (with at least a 3 mm contact gap).
