450 Flame Trap Assembly

The Varec Biogas 450 Series Flame Trap Assembly was designed for use on lines to flares and fired process units to safely prevent a flame flashback. The extensive range of sizes allows its use in many applications encountered in the typical tank farm, liquid storage facility, landfill or waste water treatment system.

The 450 Series has been designed for use on gases and should be installed no more than 15 feet from the end of the pipe nearest a possible source of ignition.

The Flame Arrester on the Varec Biogas 450 Series Flame Trap Assembly is uniquely designed with corrugated bank sheets contained within an extensible frame. The housing design allows for the removal of the entire bank assembly without the need for jack screws or other such methods which may cause stress on the piping system. The sheets can be easily inspected and cleaned.

Flow curves are provided to assist you in selecting the proper size unit for your application requirements. In addition, Varec Biogas’s applications engineering staff and factory trained representatives are always available to assist you.
