Westech Flame Arrester – Series 57

Series 57 “Fire Chief”

Westech Series 57 In-Line Detonation Arrestors are Tested in Excess of Existing Standards, complete testing through the “Flame Profile Curve”.  All Westech arresters are tested for actual field conditions not mandated by existing standards, including momentum impulse (long-run stable detonation), thermal failure and reignition of downstream unburned gases providing maximum protection against all modes of flame propagation.  The Series 57 in-line Detonation arrester is constructed with Fabricated Carbon Steel body, 304SS Elements.  The elements are designed with expanded metal 304SS sheets that when complete resemble a cartridge filter.  The expanded metal elements are designed to prevent flame transmission but allow maximum free vapour flow.  The Cylindrical Element Design providing a large Element Surface Area.  Designed up to 30 times the surface area of conventional arresters minimizing pressure drop and fouling effects decreasing downtime for maintenance.  The element design provides the LOWEST pressure drop and fouling rate of any conventional arrester, reduces costs associated with piping systems and components. The Series 57 is available for NEC Group “D” or IEC Group IIA vapours.
