IBEDA flashback arresters and
quick-action couplings fulfil the requirements of international standards, such as EN730, EN561, ISO5175 und ISO7289. All IBEDA safety devices and hose couplings are design-type tested, have met world-wide certification standards and are subject to production monitoring by neutral testing institutes. IBEDA flashback arresters and quick-action couplings are also submitted to a 100% function test. more...

IBEDA flashback arresters

Help prevent accidents and equipment damage

IBEDA flashback arresters help prevent

The entry air or oxygen into the distribution line or single cylinders
Flashback which is the rapid propagation of flame down the hose
Further gas flow in the case of burnback

1. Security against the reverse flow of gas (EN730; 3.4)

The gas non-return valve prevents leakage or the sudden return of air or oxygen in the distribution line or single cylinders.

2. Stops Flashbacks (EN730; 3.1)

A sintered stainless steel flame arrester prevents flashback from the gas outlet side and cools the flame down to below the ignition temperatur, so that the gas cannot re-ignite on the inlet side.

3. Prevent Burnbacks (EN730; 3.6)

The temperature regulated thermal cut-off valve, which is held in the open position by a soldered element. In the case of excessive temperatures in the safety device due to flashbacks or burnbacks, the valve closes automatically and cuts off the gas flow and stopps burnback.
