H 42 N Bi-directional in-line deflagration flame arrester, short-time burning proof

KITO® RG-Def-IIB3-…-1.2
KITO® RG-Def-IIB3-…-1.2-T (-TT)

  • For installation into pipes to the protection of vessels and components against deflagration of flammable liquids and gases.
  • Approved for all substances of explosion groups IIA1 to IIB3 with a maximum experimental safe gap (MESG) ≥ 0.65 mm.
  • Bi-directionally working in pipes, whereby an operating pressure of 1.2 bar abs. and an operating temperature of 60 °C must not be exceeded.
  • The distance between a potential ignition source and the flame arrester must not exceed 50 times the inner pipe diameter.
  • All sizes are tested against “stabilized burning” and withstand this up to a max. burn time BT ≤ 6.0 min.
  • To detect a “stabilized burning” a thermocouple must be installed at each endangered side.
  • Mounting is acceptable in any position, in horizontal as well as in vertical pipes.
