Special Solutions

We can realise your special requirements.

Special solutions


Customers' requirements, which cannot be met with our standard range are implemented as special solutions. These include, e.g. housings with radial air intakes or special ventilation applications..


On principle: we examine all customer's requirements with regard to feasibility and technical and economic aspects. The facility to produce our own prototypes ensures rapid implementation.

Accessories

Matched applications for your requirements.

Accessories


We offer tailor-made applications for our product in order to cater for the requirements of the installation location.

Whether you need a rain shield, an additional terminal box for connecting a brake and/or encoders, or wish to use the WISTRO connection system/plug system - our accessories provide the solution.

Services

Product development, prototype construction with DIN-compliant measuring.

Services


In addition to our range of products, we also provide a range of services with the following features:

  • Product development in close cooperation with customers
  • Prototype construction
  • Determination of product-specific data such as volume flow and noise levels by means of DIN-compliant measuring equipment

Terminal Box Plugs

Safe and secure, simple and efficient.

WISTRO Terminal Box Plugs


Advantages:


  • No need for special tools (e.g. crimping pliers), as mounting is carried out with screw terminals
  • The motor is wired to a standard terminal block (single phase and three-phase connection possible)
  • IP66 protection class guaranteed, even with lateral tension on the supply cable
  • Replacement possible without qualified personnel
  • Considerably lower costs and improved functionality
