The TNCN range comprises many standard sizes of enclosures manufactured in stainless steel 316L for maximum environmental protection. The main body is manufactured from minimum 1,5 mm sheet (depending on the box size). Cable entries can be made in all sides or optionally in gland plates. Entries may also be made in the rear face of the enclosures. Several boxes of different sizes can be flanged together as a compact unit.

If you should have a particular requirement, BARTEC AS also offer tailor made boxes. Sales staff will be pleased to advise on this.


The TNCN range of stainless steel 316L enclosures are designed for use in any environment where an explosive atmosphere may be present, and are especially recommended for chemical agent environments, seawater corrosion and extremes of low and high temperature.
