The MACROblaze flame trap is designed specifically to absorb the direct blast of an explosion and has build into the inlet side, an automatic shut-off valve which will close when a fusible plus in the outlet of the flame trap reaches an unsafe temperature.  These two features are standard equipment and form part of every MACROblaze flame trap.

 The standard MACROblaze flame traps have cast iron bodies and stainless steel heat-sinks and auto shut valves.  No brass is used in the flame trap thus making it completely suitable for use with sulphur containing gasses such as sewage sludge gas.

 For special applications non-standard valves made from other materials such as Aluminium or special stainless steels are available.

 All of the flame traps described so far are of the in-line type suitable for gas supply lines to combustion equipment etc.  Other flame traps include vent type traps for installation in the vent of large oil and combustible material storage tanks.
