(B.D.I.) Burst Disc Indicator

Continental Disc Corporation's Burst Disc Indicator (B.D.I.) Alarm System is designed specifically for use with C.D.C. Rupture Discs. Upon disc rupture, the Burst Disc Indicator strip is severed, disrupting the flow of electric current through the strip. An attached alarm monitor can then transmit a warning and/or activate appropriate equipment.

Heat Shield

Heat Shields are typically used to reduce the process temperature to which a rupture disc is exposed. Heat Shields are used where Teflon or other exotic material liners are required for corrosion resistance or as part of the rupture disc itself in combination with high process temperature.
