Vent Combination Arresters, CNC550

Additional Protection for End-of-Line Applications

These arresters are not suitable for preventing a flame from within the pipe or system igniting the surrounding area. The combination arrester provides additional protection because the flame arrester element of the system is only actively required during the short periods when the breather valve element of the system is venting.

Suitable for pipe sizes from 2″ (50mm) up to 12” (300mm).

MTP flame arresters and breather valves are certified compliant with European ATEX and PED directives where applicable.

MTP Flame Arrester and Vent Combinations work in exactly the same way as an end-of-line unit. They are designed to prevent an unconfined deflagration in the surrounding atmosphere from entering the pipe or system.

APPLICATION

These Vent Combination units are designed to be used in conjunction with a PVRV unit and installed at the end of a pipeline or exit vent on a vessel. They allow for an unrestricted flow of gases into the atmosphere and clean air into the tank/pipe therefore preventing any possible atmospheric deflagration from entering the system.

PRINCIPLE OF OPERATION

A ‘Vent Combination’ unit is designed to be mounted with a PVRV and prevent an unconfined deflagration in the surrounding atmosphere from entering the pipe or system and is not suitable for preventing a flame from within the pipe or system igniting the surrounding area.
