The Firetex Cable Tray Protection System is based upon the encapsulation of Thermal Ceramics
Firemaster Blanket, tested at Mobil's Paulsboro Research Laboratory in New Jersey and earlier by Amoco Research. The Firetex system, constructed of two 25mm thick foil-faced blankets, enclosed within a silicone coated glass cloth, has been independently tested at Warrington Fire Research Station and has been proven to provide 30 minutes cable integrity protection when exposed to a hydrocarbon fire hazard.
The system comprises two halves, the lower of which is banded to the cable rack or tray thus allowing open access to the cables therein when the top section is removed. On larger trays an open stainless steel mesh cover is supplied to carry the weight of the top cover and prevent it from laying onto the cables. The top cover is fitted by means of fire grade velcro overlaps which fold to the underside and allow the system to shed rain water, etc. Top and bottom sections are staggered by half when installed.
The body of the system is two layers of 25mm thick, foil faced, 128 kg/m3 density, Firemaster blanket.
In accordance with the overlap arrangement employed in the product testing, the sides of the top section are one layer in thickness which, when installed onto the bottom section, create a thickness of 75mm at the
The two components of the system are encapsulated within silicone coated glass cloth which provides protection from adverse environmental conditions. Mesh supports and bottom cover banding are stainless steel.
The very nature of typical cable rack/tray installations dictates that a site survey will normally be required prior to design and manufacture. Such visits will enable our engineers to design covers for transition sections, tees, bends, etc.
