The established range of ISO 9001:2000 and ISO 14001 Super 66, 78 and 90 flashback arrestors from Witt, the gas safety, control, mixing and analysis equipment supplier, have now been tested and approved for use with ethylene.

Successfully tested, the products have been approved to EN 730 standard for use with ethylene.

Ethylene C2H4 is an odourless, colourless flammable gas produced in the natural state by certain plants in their tissues, as well as being created by man made sources from natural gas and petroleum.

It is produced in the petrochemical industry by integration, where gaseous or light liquid hydrocarbons are briefly heated to 750–950°C, inducing numerous free radical reactions.

Ethylene is often used as an anaesthetic agent for accelerating the ripening of bananas and maturing the colour of citrus fruits, as well as its use in oxy-ethylene welding and cutting of metals, the manufacture of ethylene oxide, ethylene alcohol, polyethylene and other plastics and as an anaesthetic.

WITT flashback arrestors for use with ethylene, provide reliable protection of single cylinders, outlet points (hoses and any equipment) or pipelines against dangerous gas back feeding and flashbacks meeting BAM and TÜV certification. Pressure control systems, points of use and complete energy supply systems (MECS) incorporate these devices.

Witt Flashback arrestors can be mounted in any position or orientation with one flashback arrestor connected to protect each individual piece of equipment.
