A comprehensive selection of flame arresters for an ever increasing range of critical applications.

Uni-directional in-line deflagration flame arrester, short-time burning proof

KITO® RV/N-…/…-IIA

Application:

Intermediate armature, mainly installed as in-line deflagration flame arrester in pipes to thermal incineration plants for vapour/air and air/gas mixtures. Unilaterally working in pipes, whereby an operating pressure of 1.2 bar abs. and an operating temperature of 60°C must not be exceeded. Approved for all substances of the explosion group IIA with a MESG > 0.9 mm. The maximum length of the pipe from the KITO® flame arrester to the ignition source is limited (L/D tube length/tube diameter). It is only allowed to install the device in pipes with nominal widths ≤ than the nominal width of the armature (DN). The thermal sensor serves to trigger an emergency function, e.g. shutting off or inerting the gas flow if a stabilized burning occurs at the KITO® flame arrester.
