RGS Ex

RGS Ex rated cable and pipe transit are used in Ex hazardous maritime and offshore environments to minimize danger by preventing the spread of fire, water, gas chemicals and other hazards substances.

The system consists of a frame, rubber blocks and a compression unit.
The frame is welded to a 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.

Technical Specifications

RGS Ex is MCT Brattberg’s standard frame for marine applications.
It has a standard internal width of 120 mm (4.72”) and is 60 mm (2.36”) deep.
There are four sizes of RGS Ex , denoted by 2,4, 6 and 8 depending on their height. They may be used in both vertical and/or horizontal multiple frames.
The RGS Ex is welded into an accurately pre-cut hole in the deck or bulkhead. As with all our frames, RGS Ex is produced in steel, stainless steel, or aluminium.

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.
