KITO G 23.1 N – Bidirectional In-Line Detonation Flame Arrester

The KITO® CFA-Det4-IIA-…/…-… is a bidirectional in-line detonation flame arrester designed for the protection of vessels and process equipment against stable detonation in piping systems conveying flammable gases or vapors of flammable liquids. The construction is suitable for both horizontal and vertical installation and operates bidirectionally with respect to flame transmission.

Operating Limits

  • Approval: Detonation flame arrester type 4
  • Explosion groups: IIA1 to IIA
  • MESG: > 0.9 mm
  • Max pressure: 2.5 bar abs. up to NG 300
  • Max pressure: 2.0 bar abs. from NG 400
  • Operating temperature: up to 60 °C

Thermal Monitoring and Condensate Management

Variants -T and -TT are equipped with one or two PT100 sensors for certification against short-term burning from one or both sides. With a single sensor, installation is on the side where fire risk is anticipated. The body includes two drain plugs for condensate removal.

Dimensions and Materials

Available from DN 50 to DN 400, with PN 16 connections up to DN 150 and PN 10 for larger sizes. Flanges comply with EN 1092-1 type B1 or optionally ASME B16.5 Class 150 RF.

Materials:

  • Body: carbon steel or stainless 1.4571
  • Gasket: HD 3822 or PTFE
  • KITO element: fully replaceable
  • Mesh: 1.4310 or 1.4571
  • Bolts/nuts: galvanized steel or A2

Application Selection

Selection is based on explosion group, MESG, DN, pressure, temperature, pressure drop, and PT100 requirement. Flow curves are based on air at 1.29 kg/m³ and 273 K; correction required for other gases.

Description

KITO® CFA-Det4-IIA-…/…-…

KITO® CFA-Det4-IIA-…/…-…-T (-TT)

  • For installation into pipes to the protection of vessels and components against stable detonation of flammable liquids and gases.
  • Tested and approved as detonation flame arrester type 4.
  • Approved for all substances of explosion groups IIA1 to IIA with a maximum experi-mental safe gap (MESG) > 0.9 mm.
  • Bi-directionally working in pipes, whereby an operating pressure of 2.5 bar abs. up to NG 300, pmax = 2.0 bar abs. from NG 400 and an operating temperature of 60 °C must not be exceeded.
  • The installation of the detonation flame arrester into horizontal and vertical pipes is permissible.
  • Provided with one or two temperature sensors (PT 100) the armature is certified against short time burning from one or both sides.
  • If only one thermal sensor is attached, it must be installed into that part of the body from which a fire is expected.
  • Equipped with two head pipes plugs for draining condensate.
