Warning: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"? in /homepages/39/d83849026/htdocs/clickandbuilds/Joomla/website_neu/modules/mod_jf_mobilemenu/helper.php on line 79


The ALB-Box is the direct result of further development of our COM-Box with all features and benefits. The ex-proof (Ex e) box fits perfectly in the most demanding plant conditions and offers numerous technical benefits. The interior design allows installation of 2 separate switching networks. A convenient solution, which was only possible with 2 housings in the time before ALB-Box was created. Available with sensors of different designs and connections for solenoid valves, this new creation fits perfectly in different applications and diverse process plants.
