The correct type of flame arrester must be carefully selected:-
•Deflagration or detonation arrester dependent upon its position relative to the
anticipated end of line
• Inline type (unless it can be guaranteed to be at the end of line during maintenance
or after a vehicle collision)
•End of line types will need to be suitable for use with burning alcohol
•Arrester must be suitable for the correct Gas Group:-
- Ethanol blends 60% to 90% require Gas Group IIA Arresters
- Ethanol blends >90% require Gas Group IIB1 Arresters
•Arrester must be manufactured from materials suitable for use with ethanol and
bio-ethanol blended fuels
Tokheim offer two kits for use with Quantium dispensers to fullfil these
requirements, both kits using the inline deflagration flame arrester certified for
use with Gas Group IIB1 thus suitable for all percentage ethanol blends. The
kit must be installed in close proximity to the underside of the dispenser in
accordance with the drawings in this section.
•The standard kit includes an intentionally weak section above the arrester to
ensure that the device remains on the underground vapour pipe following a
vehicle collision
•The alternative kit includes a certified shear valve (with poppets) above the
arrester which additionally ensures that the line back to the tank is closed
following a vehicle collision
