MCT Ex - Marine & Offshore | RGSr Ex
At sea
Oil rigs
RGS Ex rated cable and pipe transits are used in Ex hazardous maritime and offshore environments to minimize danger by preventing the spread of fire, water, gas chemicals and other hazardous substances.
RGSr Ex
RGSR Ex is used in decks and bulkheads which are subjected to higher degrees of stress or heavier loading. The additional, rounded ends help prevent stress cracking. The RGSR Ex is welded into an accurately pre-cut hole in the deck or bulkhead.

- Available only as component.
Component:
Component is not intended to be used alone and requires additional consideration when incorporated into other equipment or systems for use in explosive atmospheres (refer to IEC 60079-0)
- Ex system combined with EMC has yellow marking on the front face (see EMC instructions)
Correct and safe installations
To achieve the highest standard of safety, a cable or pipe transit must be installed correctly. As there are many different types of frame – which may be either welded, bolted or glued into position – and insert block, it is essential that installers known when to use the most appropriate installation method.
For more information, please view following instructions, videos or download manuals as PDFs.

RGSR Ex is produced in steel, stainless steel, or aluminium.
RGSR Ex can be used in multiple frames.
For weight charts and installation details, singularly or in multiple frames, contact MCT Brattberg.
Standard frames come in eight sizes: 1, 2, 3, 4, 5, 6, 7, and 8.
The internal width can be 60.5 ± 1 (Size 1,3,5,7) or 120.5 ± 1 (2,4,6,8).
Note that there can be limitations in type-approvals & certificates, making certain sizes inapplicable.

General
The system consists of a frame, rubber blocks and a compression unit. The frame is welded or bolted to a Ex hazardous marine structure and packed with rubber blocks suited for each cable and pipe dimension. The compression unit is inserted to compress the rubber blocks against cables and pipes to establish a tight seal.
