Deflagration Flame Arrester, endurance burning proof, End-of-Line

  • endurance burning protection for alcohols and hydrocarbons up to explosion group IIB
  • specially developed for sea going vessels but also useful for inland navigation vessels and on shore systems
  • weather hood protects against environmental impact (i.e. weather, bird nests, etc.)
  • weather hood opens and signals the impact of a flame
  • fusible link is resistant against
  • modular design allows replacement of single FLAMEFILTER®
  • protection against atmospheric deflagration and endurance burning
  • modular design results in low spare part cost

Função e descrição

The PROTEGO® BE/HR-E-IIB consists of a housing (1), a weather hood (2) and the PROTEGO® flame arrester unit (3). During normal operation, the metal weather hood is in a closed position. If a flame burns on the flame arrester element surface, the fusible link (5), located in a center position, will melt and let the spring loaded weather hood move into the open position. The PROTEGO® flame arrester unit consists of two FLAMEFILTER® discs (4), which are installed in a FLAMEFILTER® casing. The PROTEGO® BE/HR-E end-of-line deflagration flame arrester is available for hydrocarbons for explosion group IIB (MESG ≥ 0,5 mm) and alcohols.

The standard design can be used for operating temperatures up to +60°C / 140°F.

Type-approved in accordance with ATEX Directive and EN ISO 16852 as well as other international standards. Approved according to IMO MSC/Circular 677 as well as IMO MSC.1/Circular 1324 and 1325.

Diagrama de vazão

Este diagrama de vazão foi determinado em uma bancada de medição de vazão calibrada e certificada pela TÜV. A vazão V em m³/h se refere ao estado técnico padrão de ar, conforme ISO 6358 (20°C, 1bar). Para conversão em outras densidades e temperaturas, veja o cap. 1: Bases técnicas.
