Description
The Protego LDA-WF(W) series of liquid detonation flame arresters was developed for storage container filling lines that are not continuously filled with product and sometimes contain a combustible mixture.
The integrated siphon protection with Protego flame arrester unit additionally prevents the liquid in which the lines are immersed from being siphoned off while the container is being drained.
Protego flame arrester consists of several FLAMEFILTER discs and spacers firmly held in a FLAMEFILTER cage. The number of FLAMEFILTER discs and their gap size depends on the arresters conditions of use.
Features- The device is easily accessible since it is mounted on the containers outside
- Siphon protection offers a high degree of safety
- Minimum risk of soiling
- Low pressure loss
- Provides protection from deflagrations and stable detonations
- Useful for nearly all flammable liquids
- Meets TRbF (Technical Regulations for Flammable Liquids) requirements
