Our Products


DuraSystems’ DuraBarrier is designed for easy installation and is fire, blast, moisture, and impact resistant. DuraBarrier is demountable for easy maintenance or replacement of transformer or equipment. In addition, the DuraBarrier is corrosion resistant, maintenance free, and cost competitive. The standard DuraBarrier is made of hot dipped galvanized, with stainless & specialty metals also available.
DuraSystems’ DuraBarrier helps protect life, property, and the environment.

 The DuraBarrier was selected by Energy Northwest in Washington State as a transformer separation.

If requirements for a DuraBarrier are not met by the above conditions, DuraSystems will provide a custom engineered solution to meet your needs. With the benefit of modular construction, the DuraBarrier offers quick and easy installations and allows for the future disassembly and reassembly for maintenance or replacement of the equipment protected. This benefit ensures downtime and interruptions are kept to an absolute minimum.

The above options should provide the selection and flexibility to meet virtually all possible transformer applications and its modular design and bolted on site connections make it quick and easy to install.

Transformer Isolation Barriers

DuraSystems` DuraBarrier is a barrier that will help protect people and property from the growing number of transformer failures. 
Electricity is taken for granted and it is only when the lights go out and life comes to a standstill that people suddenly become aware of their dependency on electrical equipment such as transformers.
Transformers are a fundamental component of electrical distribution and transmission networks.  Most people are not aware of the fact that transformers are subject to faults.  Transformers sometimes explode and/or catch fire without warning.  When a catastrophic fire or explosion occurs, the damage and costs can be immense.  Equipment replacement, cleanup and repair, and lost revenue can run into the 10’s of millions of dollars. 
Insurers and corporate risk managers consider transformers to be the most critical electrical components within facilities today.  This is due to the quantity of oil contained within the transformer, its contact with high voltage elements and the dangers involved with failure. Transformer continue to fail at an increasing rate year over year.
Two specific transformers statistics that deserve special attention are the current average age of transformers and the increased loads they are expected to supply.  The average age of transformers in North America is 35 years, which means that many, with an optimistic life span of 40-50 years are coming to the end of their usefulness.  There is also a problem with increased loads.  World energy consumption has grown from 1 trillion to 11 trillion kW/hr in the decades following World War II.  Transformers were not designed to handle such heavy loads.
These emerging risk factors have caused many insurance companies to demand protection of the transformers they insure. This is why the DuraBarrier was developed.  DuraSystems has designed and developed a barrier system that meets the requirements of FM Global Property Loss Data Sheet 5-4 for exterior transformers and most stringent fire protection requirements for fire exposure on both sides.   
DuraSystems recognized the need for transformer protection that could be installed in confined spaces and was quick and easy to erect unlike concrete barriers.  Due to its relatively low weight, the DuraBarrier requires simpler and smaller foundations than poured concrete or concrete block methods.  This can result in significant cost savings especially with retrofit applications where existing equipment is being upgraded/replaced or existing underground service foundations cannot be disturbed.
The DuraBarrier is a modular pre-engineered barrier system.  DuraBarrier pre-engineered systems are available to meet the following conditions:
  •   Tested to 6 hours of fire protection
  •   Interior and exterior installations
  •   Seismic Resistant
  •   Galvanized, stainless steel and epoxy finishes 
  •   Noise reduction
  •   Wind conditions up to and including category 5 hurricanes
  •   Pre-design barrier heights up to 35 feet 
  •   Barriers can be custom designed to any height required
  •   Barrier widths are unlimited
  •   Available with both 90 degree and T joint connections
  •   Available for both continuous and pier foundation methods
The DuraBarrier is also available to provide the following options: 
  • Acoustic Reduction & Absorption
  • Ballistic Ratings
  • Blast Resistance
  • Hydrocarbon Fire Resistance
    • H60
    • H120
  • Jet Fire Resistance


Ballistic Resistant Barriers

DuraSystems also offers DuraBarrier with ballistic resistance. Offering protection against complete penetration and passage of fragments, you can be asured that the stability and integrity of the occupants will not be compromised. Systems are designed in compliance with UL752 Ballistic Standards and/or National Institute of Justice (NIJ) ballistic resistance standards.

Fire & Blast Rated Duct


DuraDuct SD & HP are independently tested blast rated duct systems. Both SD & HP models can withstand a charge of 2 Bar (approx. 27psi) overpressure without developing any through openings.

This life safety benefit is unmatched by any other fire rated duct system and is the only tested blast rated system on the market.

DuraDuct SD & HP models are ideal for high risk installations or where added protection of the life safety system will be required.
