Nook Industries offers a highly configurable line of modular linear actuators specially developed for explosion-protection zones. These linear actuators are are commonly used in bottling technology for explosive substances such as:

  • Alcohol
  • Benzene
  • Gasoline
  • Flammable Chemical Liquids

Available in a variety of lengths and drive properties, these linear motion systems can be designed and built to the exact requirements of the application. These linear actuators are specially developed for the explosion-protection field meet the highest safety standards in accordance with the following guidelines:

  • ATEX-R2014/34/EU
  • II 2G Ex h IIB T4 Gb
  • II 3D Ex h IIIB T125°C Dc
  • ISO 80079-36:2016
  • ISO 80079-37:2016
  • Technical Rules for Hazardous Substances (TRGS) 727

Toothed belt driven linear actuators axes from the ELZex and ELFZex series are certified for use in explosion-protection areas. The linear systems conform with the new EN ISO 80079-36 and -37 norm for mechanical explosion protection. Furthermore, the axes are ATEX-approved and can therefore be used in Zone 2 for gas and dust.

With this approach, it is possible to easily meet the demands of many new applications. The modular linear actuator systems are designed as a complete package to also include accessories such as limit switches and couplings with ATEX approval.
