IsoMod Modular Fire Barrier Walls

(Contact us to learn more information, or scroll below to receive a quote for consideration)

Modular Fire Barrier Walls are installed around electrical transformers to protect

adjacent property and equipment from fire, shrapnel debris, and other side effects resulting from transformer explosions.  We will be glad to install the walls for you, or work with an existing contractor.


Without Walls                                       With Walls


The consequences of a transformer explosion are extremely significant.  Here at SRE we have developed

a modular precast wall to fit your needs from both a cost and an installation standpoint.


IsoMod vs. Deluge System Option

Risky Deluge System Option:
Deluge systems are not always accountable.  Sediments collected in the pipes, frozen water and poor water pressure all contribute to deluge system failures.  Overall maintenance of deluge systems are a full time job in and of themselves.  In addition, as water from the deluge system and oil from the transformer overfill the drainage pit, the fire is likely  to flow beyond the limits of control.  Engineers are jointly coming to the conclusion that deluge systems may not be the most effective way to protect surrounding assets.

Secure IsoMod Barrier Wall Option:
In the unfortunate event of a fire, barrier walls have proven time and again to effectively contain fire spread and protect surrounding equipment from shrapnel debris.  Once installed, equipment owners can direct their focus to other crucial tasks as opposed to regularly maintaining the walls.
