Actuators as an OEM system solution

Actuators quite unlike the others

WE CAN CREATE YOUR PERFECT SOLUTIONDevelopment power meets standard product range

For us, your requirements are the yardstick we apply when developing an actuator specifically for you:

  • Your direct points of contact on the project are there to respond promptly and to come up with a swift solution to any problems.
  • Benefit from professional advice and responsive teams for customer-specific and flexible solutions.
  • We bring a lot of experience to bear and we deliver an optimum Return on Investment by adapting standards to suit your needs.

Do you wish us to develop something entirely new for you?

No problem: we provide the scope needed to create new technical solutions.

Regardless of which path you choose as our partner for OEM actuators – we can provide you with the following benefits:

  • Our solutions can extend the range of applications for your products.
  • You can reduce costs, for your own in-house production and for your customers.
  • You also boost operational reliability with our robust technology.

The ideal OEM system solutionYour actuator parameters are feasible

Standard products are no longer sufficient for doing justice to requirements relating to current planning and practice on construction sites. To save time and cost, components not only need to be tailored precisely to meet specific requirements, they also need to be easy to integrate in installation and connection terms. We implement this Plug & Play concept by integrating your OEM actuator into your system perfectly. With these comprehensive solutions, we can adapt our products perfectly to suit the requirements of your projects:

  • Your individual branding in the desired colour, including logo and other markings
  • Precise design of connectors and made-to-measure cable assembly
  • Prior definition of parameters in accordance with your specifications
  • Pre-assembled connection parts for air vents, valves and sensors

Intelligent production

Benefit from our absolute flexibility in the creation of bespoke solutions: to accomplish this, we use the very latest production technology which meets Industry 4.0 standards. And we remain in control at all times thanks to our unique level of vertical integration.

GrunerHVAC range

Gruner actuators for HVAC solutions assure uniform air distribution and great cooling power. Our most recently developed actuators are able to link multidimensional parameters such as static pressure, dynamic pressure and travel distance, delivering draught-free cooling through a controlled, constant discharge of air.

Gruner actuatorsfor the control of valves

We also know all about valves: whether liquid or gaseous – the reliable adjustment and closing of valves by actuator is very much a topic in our portfolio. We not only offer you actuator solutions for pretty much every conceivable variant of ball valve, we can also provide you with the right ball valves for whichever medium or media you need to control.
