Flame Arrestors

Low speed, low pressure solution

A SUPERIOR SOLUTION

Working in the petrochemical industry for over 35 years, Prism is a leading manufacturer of flame arrestors. While all flame arrestors operate on the same principle, they are not all created equal. Critical for safe operation, we deliver patented technologies for maximized flame propagation prevention with choices all in-line or end-of-line applications.

What's the Difference? know your cells

detonation arrestor

Grid Cell

Alternating stacks of flat bar and crimped ribbon form a consistent/solid surface that allow full flow through of gas without allowing any of the insulation beads to migrate.

Flame Arrestor

Spiral Cell

Ribbon is welded to a core and wrapped around itself. This creates narrow channels that lazy flames can’t pass through. Not compatible with all flame fronts/configurations.

CRFA (Crimped Ribbon Flame Arrestor)

Maximum SCFH. Gas molecular weight calculated as air. Call for exact sizing.

Why Flame Arrestors?

Flame arrestors are a critical safety device and a component in the safe operation of vapor control systems. They are a device fitted to the opening of an enclosure or to the connecting pipe work of a system of enclosures and whose intended function is to allow flow but prevent the transmission of flame propagating at supersonic velocity. Flame arrestors are passive devices with no moving parts. They prevent the propagation of flame from the exposed side of the enclosed flare system to the protected side using metal matrix creating a tortuous path called a flame cell or element.

Prism Flame Arrestors

Patented, state-of-the-art technology working for you!

Offering a wide array of flame arrestor technology, Prism has a choice for every configuration. The selection of the appropriate arrester depends on the flammable properties of the vapor/air mixture, operating conditions as well as how and where the arrester is installed with respect to the potential ignition source. The user must be assured that the arrester selected has been tested for conditions that match or exceed the intended application.
