Information
WITT Decomposition Blockers for reliable protection against decomposition of acetylene and flashbacks of fuel gases. Every Arrestor 100% tested.
The best Safety Devices in the world
- a large surface area flame arrestor of stainless steel construction:
- stops dangerous decomposition of acetylene independent from flow direction
- extinguishes any dangerous flashback entering the device in any direction - a temperature-sensitive cut-off valve extinguishes sustained flashbacks long before the internal temperature of the arrestor reaches a dangerous level
Operation / Usage:
- as a Decomposition Blocker for acetylene in medium-pressure pipelines for protection of cylinder equipment and bundles in accordance with DIN EN ISO 14114
- as a Decomposition Blocker to protect pipelines in supply systems
- FN40 for double flow capacity
- WITT Decomposition Blockers may be mounted in any position / orientation
- the maximum ambient / working temperature is 60 °C / 140 °F
Maintenance:
- it is recommended that an annual body leakage test is performed
- decomposition Blockers are only to be serviced by the manufacturer
